I need to use a script based upon xxd, but it's not installed on my Fedora 21:
$ xxd
bash: xxd: command not found
So I tried without success to search and install it:
$ yum install xxd
(fails)
$ yum search xxd
(fails)
$ yum search all xxd
(fails - detailed log below)
Loaded plugins: langpacks
================================================================= Matched: xxd ========
perl-Data-HexDump-XXD.noarch : Format hexadecimal dump like xxd
xxdiff.i686 : Graphical file and directories comparator and merge tool
xxdiff-tools.i686 : Tools for xxdiff
Do you know which package xxd is provided with? (I mean an official package to install with yum from the fedora repositories).
Thanks in advance for any help!
xxd is in the vim-common package.
You can find that by using yum whatprovides '*bin/xxd'.
Have you tried
yum install vim-common

I have just upgraded my Macbook Pro OS to El Capitan (v10.11.4).
My attempt to export a Markdown file (created using Sublime Text 2, v2.0.2, build 2221) to pdf using pandoc is now failing, and I receive the following error:
pandoc: xelatex not found. xelatex is needed for pdf output
My output command is as follows:
pandoc doc1.md -o doc1.pdf --toc -V geometry:margin=1in --variable fontsize=10pt --variable fontfamily=utopia --variable linkcolor=blue --latex-engine=xelatex -f markdown-implicit_figures -s
Above command worked like a charm prior to installing El Capitan.
FYI - in searching for questions here I have not found one that gives a suitable answer.
For my case, add one line into ~/.bashrc solved the error:
export PATH=/Library/TeX/texbin:$PATH
Of course, the environment variable should be activated in the current term:
$ . ~/.bashrc
then run: $ make
the error disappears.
El Capitan's security features disable and remove the old symlink /usr/texbin. If you have MacTeX 2015, they should've been installed in /Library/TeX/texbin as well. You'll have to update the PATH your using to launch pandoc to include that folder. If you have a pre-2015 distribution of MacTeX, there are instructions here.
Linux Ubuntu instructions:
Tested on Ubuntu 18.04:
If you see this error on Linux Ubuntu:
pandoc: xelatex not found. xelatex is needed for pdf output
Then you need to install the texlive-xetex package like this:
sudo apt update
sudo apt install texlive-xetex
That solves it! Source where I learned this: TEX: XeLatex under Ubuntu.
In my particular case, I was trying to run this make_book.sh script to generate book.pdf, so I needed to do all of the following:
sudo apt update
sudo apt install pandoc
pip3 install MarkdownPP
sudo apt install texlive-xetex
cd path/to/repo
cd systemd-by-example
./make_book.sh
# You'll now have "book.pdf" inside directory "systemd-by-example"!

I come from a python background and I'm hoping to do something semantically equivalent to pip install -r requirements.txt to install a list of Python packages at the right version.
Is this achievable with luarocks? If not, is there a way to hack this together on the command line?
The system in Lua is a little different. There is a rockspec manifest file associated with every package. You can list your package dependencies here in this file and you can install then using
"luarocks install name.rockspec".
For more details, visit Luarocks
More on Rockspec format here
Instruction for creating a package/rock here
In case you just want to install a list of dependencies from a file without worrying about Rockspec, you can also just use this three lines that read a file with the exact same format of a requirements.txt file for pip (package==version):
while read -r line ; do
luarocks install $(echo $line | awk -F '==' '{print $1, $2}')
done < lua_requirements.txt
Most (all?) information online is outdated since ECW (Hexagon Geospatial/Intergraph) has recently released new versions with breaking changes (5.0, 5.1 and 5.2).
Most instructions result in errors like:
checking for libNCSEcw.so or libecwj2... configure: error: not found in /usr/local/lib or /usr/local/bin
This works for GDAL 1.11.2, but it should work back to 1.10.0.
Download the latest version of the ECW library from here (currently 5.5):
https://download.hexagongeospatial.com
Instructions for v5.2.1, but should be similar for the latest version:
$ unzip erdas-ecwjp2sdk-v5.2.1-linux.zip
$ chmod +x ERDAS_ECWJP2_SDK-5.2.1.bin
$ ./ERDAS_ECWJP2_SDK-5.2.1.bin
Choose Desktop Read-Only and accept the license. A directory named hexagon is extracted. Copy that to /usr/local.
$ sudo cp -r hexagon/ERDAS-ECW_JPEG_2000_SDK-5.2.1/Desktop_Read-Only /usr/local/hexagon
Link the .so library for the correct architecture:
$ sudo ln -s /usr/local/hexagon/lib/(x64|x86)/release/libNCSEcw.so /usr/local/lib/libNCSEcw.so
Then configure GDAL with this command:
$ ./configure --with-ecw=/usr/local/hexagon
Before I could see ECW support in gdalinfo --formats | grep -i ecw
I also had to run sudo ldconfig.
That was in Ubuntu 14.04 Linux.
I've just installed RVM on a new machine and when switching into a directory containing a .rvmrc file (which I've accepted) I'm getting:
ERROR: Neither sha256sum nor shasum found in the PATH
I'm on OS X 10.5.8. — Probably missing something somewhere. Any ideas what's going on and how to fix this?
My OpenSSL happened to not have a sha256 enc function for some reason:
$ openssl sha256
openssl:Error: 'sha256' is an invalid command.
After some googling, I found that there is an equivalent called gsha256sum that comes with the homebrew recipe "coreutils". After installing that (brew install coreutils), I had a gsha256sum binary in /usr/local/bin, so it was just a matter of symlinking it:
$ sudo ln -s /usr/local/bin/gsha256sum /usr/local/bin/sha256sum
That fixed it for me.
ciastek's answer worked for me until I tried to run rvm within a $() in a bash script - rvm couldn't see the sha256sum function. So I created a file called sha256sum with the following contents:
openssl sha256 "$#" | awk '{print $2}'
put it in ~/bin, made it executable, and added that folder to my path (and removed the function from my .bashrc).
(Many thanks to my coworker Rob for helping me find that fix.)
Means you're missing the binary in /usr/bin or your path is somehow missing /usr/bin. Open a new shell and run echo $PATH | grep '/usr/bin' and see if its returned. Also, ls -alh /usr/bin/shasum and make sure the binary is there and executable. There is no sha256sum on OS X, just shasum.
On MacOS Sierra run
$ shasum -a 256 filename
Based on #vikas027 comment just add
alias sha256sum='shasum -a 256' to your ~/.zshrc
In my opinion Leopard just doesn't have /usr/bin/shasum.
Take a look at shasum manpage - this manpage is only for Snow Leopard. Other manpages, like ls manpage (can't link to it, not enough reputation), are for previous versions of MacOS X.
Workaround: Use OpenSSL to calculate sha256 checksums.
Leopards' OpenSSL (0.9.7) doesn't handle sha256. Upgrade OpenSSL. I've used MacPorts (can't link to it, not enough reputation). OpenSSL's dependecy zlib 1.2.5 required to upgrade XCode to 3.1. Can I get Xcode for Leopard still? is helpful.
Alias sha256sum to OpenSSL and correct the way it formats an output. I've put in my .bash_profile:
function sha256sum() { openssl sha256 "$#" | awk '{print $2}'; }
I'm on a relatively fresh install of Lion (OS X 10.7.4). In my /usr/bin/ folder I had these files:
-rw-rw-rw- 35 root wheel 807B /usr/bin/shasum
-rwxr-xr-x 1 root wheel 7.5K /usr/bin/shasum5.10
-rwxr-xr-x 1 root wheel 7.5K /usr/bin/shasum5.12
I had a shasum, it just wasn't marked as executable. A quick sudo chmod a+x /usr/bin/shasum solved the issue for me.
For mac os X 10.9.5 and you profile get /usr/bin path
date +%s | shasum | base64 | head -c 32 ; echo
And if you found yourself here in 2022 wondering what works on the latest Mac (Mac OS Big Sur). Do following.
sudo brew install coreutils
sudo ln -s /usr/bin/shasum<Version_for_your_installation> /usr/local/bin/sha256sum
I have tried in all ways to get wkhtmltopdf installed on our web server but unfortunately it is not getting installed. I cannot access user/bin folder as stated in a tutorial on installation.
On the server in public_html folder there is a sub folder _vti_bin, I copied the file wkhtmltopdf-i386 from wkhtmltopdf-0.9.1-static-i386, but I am not able to execute it.
How to install wkhtmltopdf on (shared hosting) web server and get it working?
I've managed to successfully install wkhtmltopdf-amd64 on my shared hosting account without root access.
Here's what i did:
Downloaded the relevant static binary v0.10.0 from here: http://code.google.com/p/wkhtmltopdf/downloads/list
EDIT: The above has moved to here
via ssh on my shared host typed the following:
$ wget {relavant url to binary from link above}
$ tar -xvf {filename of above wget'd file}
you'll then have the binary on your host and will be able to run it regardless of if its in the /usr/bin/ folder or not. (or at least i was able to)
To test:
$ ./wkhtmltopdf-amd64 http://www.example.com example.pdf
Note remember that if you're in the folder in which the executable is, you should probably preface it with ./ just to be sure.
Worked for me anyway
If you have sudo access...
Ubuntu 14.04 / 15.04 / 18.04:
sudo apt-get install wkhtmltopdf
# or
sudo apt install wkhtmltopdf
Others
Look at the other answers.
If its ubuntu then go ahead with this, already tested.:--
first, installing dependencies
sudo aptitude install openssl build-essential xorg libssl-dev
for 64bits OS
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-amd64.tar.bz2
tar xvjf wkhtmltopdf-0.9.9-static-amd64.tar.bz2
mv wkhtmltopdf-amd64 /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
for 32bits OS
wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.9.9-static-i386.tar.bz2
tar xvjf wkhtmltopdf-0.9.9-static-i386.tar.bz2
mv wkhtmltopdf-i386 /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
Debian 8 Jessie
This works
sudo apt-get install wkhtmltopdf
Chances are that without full access to this server (due to being a hosted account) you are going to have problems. I would go so far as to say that I think it is a fruitless endeavor--they have to lock servers down in hosted environments for good reason.
Call your hosting company and make the request to them to install it, but don't expect a good response--they typically won't install very custom items for single users unless there is a really good reason (bug fixes for example).
Lastly, depending on how familiar you are with server administration and what you are paying for server hosting now consider something like http://www.slicehost.com. $20 a month will get you a low grade web server (256 ram) and you can install anything you want. However, if you are running multiple sites or have heavy load the cost will go up as you need larger servers.
GL!
Latest update for CentOS:
sudo yum install -y libpng libjpeg openssl icu libX11 libXext libXrender xorg-x11-fonts-Type1 xorg-x11-fonts-75dpi
wget https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar -xvf wkhtmltox-0.12.4_linux-generic-amd64.tar
sudo mv wkhtmltox/bin/* /usr/local/bin/
check installation success: wkhtmltopdf -V
rm -rf wkhtmltox
rm -f wkhtmltox-0.12.4_linux-generic-amd64.tar
Place the wkhtmltopdf executable on the server and chmod it +x.
Create an executable shell script wrap.sh containing:
#!/bin/sh
export HOME="$PWD"
export LD_LIBRARY_PATH="$PWD/lib/"
exec $# 2>/dev/null
#exec $# 2>&1 # debug mode
Download needed shared objects for that architecture and place them an a folder named "lib":
lib/libfontconfig.so.1
lib/libfontconfig.so.1.3.0
lib/libfreetype.so.6
lib/libfreetype.so.6.3.18
lib/libX11.so.6 lib/libX11.so.6.2.0
lib/libXau.so.6 lib/libXau.so.6.0.0
lib/libxcb.so.1 lib/libxcb.so.1.0.0
lib/libxcb-xlib.so.0

lib/libXdmcp.so.6
lib/libXdmcp.so.6.0.0
lib/libXext.so.6 lib/libXext.so.6.4.0
(some of them are symlinks)
… and you're ready to go:
./wrap.sh ./wkhtmltopdf-amd64 --page-size A4 --disable-internal-links --disable-external-links "http://www.example.site/" out.pdf
If you experience font problems like squares for all the characters, define TrueType fonts explicitly:
#font-face {
font-family:Trebuchet MS;
font-style:normal;
font-weight:normal;
src:url("http://www.yourserver.tld/fonts/Trebuchet_MS.ttf");
format(TrueType);
}
List of stable versions wkhtmltopdf: http://wkhtmltopdf.org/downloads.html
Installing wkhtmltopdf on Debian 8.2 (jessie) x64:
sudo apt-get install xfonts-75dpi
sudo apt-get install xfonts-base
sudo wget http://download.gna.org/wkhtmltopdf/0.12/0.12.2.1/wkhtmltox-0.12.2.1_linux-jessie-amd64.deb
sudo dpkg -i wkhtmltox-0.12.2.1_linux-jessie-amd64.deb
Shared hosting no ssh or shell access?
Here is how i did it;
Visit https://wkhtmltopdf.org/downloads.html and download the appropriate stable release for Linux. For my case I chose 32-bit
which is wkhtmltox-0.12.4_linux-generic-i386.tar.xz
Unzip to a folder on your local drive.
Upload the folder to public_html (or whichever location fits your need) using an FTP program just like any other file(s)
Change the binary paths in snappy.php file to point the appropriate files in the folder you just uploaded.
Bingo! there you have it. You should be able to generate PDF files.
A few things have changed since the top answers were added. They used to work out for me, but not quite anymore, so I have been hacking around for a bit and came up with the following solution for Ubuntu 16.04. For Ubuntu 14.04, see the comment at the bottom of the answer. Apologies if this doesn't work for shared hosting, but it seems like this is the goto answer for wkhtmltopdf installation instructions in general.
# Install dependencies
apt-get install libfontconfig \
zlib1g \
libfreetype6 \
libxrender1 \
libxext6 \
libx11-6
# TEMPORARY FIX! SEE: https://github.com/wkhtmltopdf/wkhtmltopdf/issues/3001
apt-get install libssl1.0.0=1.0.2g-1ubuntu4.8
apt-get install libssl-dev=1.0.2g-1ubuntu4.8
# Download, extract and move binary in place
curl -L -o wkhtmltopdf.tar.xz https://github.com/wkhtmltopdf/wkhtmltopdf/releases/download/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar -xf wkhtmltopdf.tar.xz
mv wkhtmltox/bin/wkhtmltopdf /usr/local/bin/wkhtmltopdf
chmod +x /usr/local/bin/wkhtmltopdf
Test it out:
wkhtmltopdf http://www.google.com google.pdf
You should now have a file named google.pdf in the current working directory.
This approach downloads the binary from the website, meaning that you can use the latest version instead of relying on package managers to be updated.
Note that as of today, my solution includes a temporary fix to this bug. I realize that the solution is really not great, but hopefully it can be removed soon. Be sure to check the status of the linked GitHub issue to see if the fix is still necessary when you read this answer!
For Ubuntu 14.04, you will need to downgrade to a different version of libssl. You can find the versions here. Anyways, be sure to consider the implications of downgrading libssl before doing so on any production server.
I hope this helps someone!
After trying, below command work for me
cd ~
yum install -y xorg-x11-fonts-75dpi xorg-x11-fonts-Type1 openssl git-core fontconfig
wget https://downloads.wkhtmltopdf.org/0.12/0.12.4/wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
tar xvf wkhtmltox-0.12.4_linux-generic-amd64.tar.xz
mv wkhtmltox/bin/wkhtmlto* /usr/bin
Version 12.5 of wkhtmltopdf only lists DEB files on their download page now. Being a mac user and not knowing much linux or what DEB files were I couldn't use the solutions posted.
This page helped me get past the knew twist of downloading a DEB file: http://www.g-loaded.eu/2008/01/28/how-to-extract-rpm-or-deb-packages/
Basically what I did was:
Downloaded from https://wkhtmltopdf.org/downloads.html
Unzipped the DEB file.
Unzipped data.tar.xz
Uploaded the binary in the unzipped 'usr' folder from step 3 (usr/local/bin/wkhtmltopdf)
Then I found out that the 'exec' function was disabled on my host. So make sure you can specifically run 'exec' if you're using PHP to run this. "Can I run the wkhtmltopdf binary" isn't specific enough. My fault.
