How to open Gzipped text files (*.gz) in Gvim without unzipping them first ?
Solution mentioned in VimDocs as answered by therefromwhere
augroup gzip
autocmd!
autocmd BufReadPre,FileReadPre *.gz set bin
autocmd BufReadPost,FileReadPost *.gz '[,']!gunzip
autocmd BufReadPost,FileReadPost *.gz set nobin
autocmd BufReadPost,FileReadPost *.gz execute ":doautocmd BufReadPost " . expand("%:r")
autocmd BufWritePost,FileWritePost *.gz !mv <afile> <afile>:r
autocmd BufWritePost,FileWritePost *.gz !gzip <afile>:r
autocmd FileAppendPre *.gz !gunzip <afile>
autocmd FileAppendPre *.gz !mv <afile>:r <afile>
autocmd FileAppendPost *.gz !mv <afile> <afile>:r
autocmd FileAppendPost *.gz !gzip <afile>:r
augroup END
Vim should do this for you automatically. At least it does for me. There's also zless. I'll see if I can find a resource that talks about how vim does this.
There's a example in the vim docs how how to get this working: http://vimdoc.sourceforge.net/htmldoc/autocmd.html#gzip-example
For what it's worth I didn't need to do this on Ubuntu 10.04 (vim v7.2), it worked out of the box.
Opening them directly would just give you the raw binary compressed data. There's tools for everything, but they need to be used appropriately. Sledgehammers are not there to break eggs for breakfast, and text editors aren't there to unzip.

When I drag a PDF file in a VIM Tab I want to convert it to a TXT file using pdftotext. (I've installed pdftotext on my disk)
To do this I added this cmd in vimrc:
autocmd BufReadPost *.pdf silent %!pdftotext -layout -q -eol unix "%"
In vim 7.4 it worked fine. It opened the PDF file in TXT format.
Now in vim 8.1 it doesn't work as expected. It converts the PDF and creates the TXT file on my disk (in the same PDF directory) without opening it.
What I want is to create the TXT file always in the same directory "D:\temp", close the PDF file and open the TXT file.
I tried this but without success:
autocmd BufReadPost *.pdf silent %!pdftotext -layout -q -eol unix "%" | :let myfile = "D:\\temp\\".expand("%:r").".txt" | :bd | :exe "tabe ".myfile
Error: The filename, directory name, or volume label syntax is incorrect
How can I create the TXT file in "D:\temp", close the PDF and open the created TXT file in a new tab?
It makes more sense, IMO, simply to replace the buffer contents.
let g:Pdf2Txt = 'pdftotext -layout -q -eol unix %:p:S -'
augroup Pdf2Txt | au!
autocmd BufReadCmd *.pdf execute expandcmd('silent read ++edit !'..g:Pdf2Txt)
autocmd BufReadCmd *.pdf 1delete_
autocmd BufReadCmd *.pdf setfiletype text
autocmd BufReadCmd *.pdf setlocal buftype=nowrite
augroup end
It converts the PDF and creates the TXT file on my disk
It's not vim's fault, it's pdftotext's. For quite some time has been behaving this way. You need to force it to write to stdout by appending - which means "output file is stdout":
autocmd BufReadPost *.pdf silent %!pdftotext -layout -q -eol unix "%" -
How can I read the files contained in the directory d:\ with batchscript not one by one files like that. I have tried the following:
#echo off
"C:\Program Files\gs\gs9.25\bin\gswin32c.exe" -sDEVICE=pdfwrite -dCompatibilityLevel=1.3 -dPDFSETTINGS=/printer -dColorImageResolution=90 -dAutoRotatePages=/None -dBATCH -dNOPAUSE -sOutputFile=d:\d\koran.pdf *d:\a\01.pdf d:\a\02.pdf d:\a\03.pdf d:\a\04.pdf d:\a\05.pdf d:\a\06.pdf d:\a\07.pdf d:\a\08.pdf d:\a\09.pdf d:\a\10.pdf d:\a\11.pdf d:\a\12.pdf d:\a\13.pdf d:\a\14.pdf d:\a\15.pdf d:\a\16.pdf d:\a\17.pdf d:\a\18.pdf d:\a\19.pdf d:\a\20.pdf d:\a\21.pdf d:\a\22.pdf d:\a\23.pdf d:\a\24.pdf*
exit
Ghostscript doesn't 'merge' PDF files. It creates new PDF files by interpreting the contents of its input, this is not the same thing. You should read the documentation here
You haven't said what the problem is with the command you have tried, its going to be hard to help you if you don't do that.
The most likely problem is that you have put * characters at the start and end of the input filenames. Ghostscript itself doesn't match wildcards, it expects you to tell it each file you want to process individually. So in order to process a directory of files is to first get a list of all the files, and then tell Ghostscritp to use each of those files in turn.
You can use the Ghostscript #filename syntax (documented here)to tell Ghostscript to use the contents of a file as if it were the command line.
So all you need to do is come up with a shell script which will write the filenames from a folder into a file. That's not a Ghostscript question, and depends totally on the operating system you are using.
For Windows something like:
dir /B *.pdf >> files.txt
gswin32c -sDEVICE=pdfwrite -dBATCH -dNOPAUSE -sOutputFile=\temp\out.pdf #files.txt
del files.txt
might be sufficient for your needs.
I could not make it work using "files.txt" but I am using this and everything works just fine.
gswin64c -sDEVICE=pdfwrite -dBATCH -dNOPAUSE -sOutputFile="out.pdf" (Get-ChildItem -Path .\*.pdf)
You can execute like below:
gs -dBATCH -dNOPAUSE -q -sDEVICE=pdfwrite -sOutputFile=merged.pdf *.pdf

I have a folder which contains a lot of .gz files, each of them contains los as text.
It's too troublesome to unzip and look through them one by one. So I'm wondering is there any command to unzip content of mutiple .gz files to a same file?
Thanks
This is the command you want probably:
cat *.gz | gzip -dc - | grep los
First the cat *.gz sends all the zipped files to stdout.
Using gzip the -d switch decompresses and -c sends output to stdout. The "-" allows input to come from stdin rather than through files.
Then this output can be piped to whatever program you want.
If you want to know the specifically each file that has matches you can do this too:
for f in *.gz
do echo $f: ;
gzip -dc $f | grep los ;
done
I have many .sql files in subfolders. I am presently manually opening them up, and searching for OLDSERVERNAME, and replacing it with NEWSERVERNAME(I'm doing migration). There must be a faster way to do this. I tried using FART, but I guess I wasn't doing it right.
This is what I tried(in main folder):
fart -i -p -c *.sql OLDSERVERNAME NEWSERVERNAME
Can I perhaps use unix utilities for this purpose?
You can use sed for this. sed stands for S tream Ed itor
sed -i 's/OLDSERVERNAME/NEWSERVERNAME/g' *.sql
-i option will do in-file substitution.
g implies global substitution. So if there are more than one instances of OLDSERVERNAME in one line they will get replaced with NEWSERVERNAME
*.sql will pass all files ending with .sql extension.
Look up sed man page for more details.
On MacOS - I had to add a backup file extension
sed -i '.bak''s/OLDSERVERNAME/NEWSERVERNAME/g' *.sql
Trying to merge all pdfs in a directory using GhostScript 9.06 64bit in a .bat file
The following, makes merged.pdf, but it is 1 page and blank
call gswin64c -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=merged.pdf *.pdf
If I actually specify which PDFs to merge it works fine. What gives?
call gswin64c -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=merged.pdf 1.pdf 2.pdf 3.pdf
You can't specify wildcards on the Ghostscript command line, simple as that.
Since GS didn't find a file called '*.pdf' it didn't execute any marking operations, in this case you get a blank file.
Ghostscript cannot do wildcard expansions by itself.
If you call gs ... *.pdf from inside a shell which can do wildcard expansion, it will work nevertheless.
There is a difference with the site you linked to and the code you used above:
Your code is DOS batch and uses call gswin64c .... But as said, Ghostscript cannnot expand wildcards itself.
The code in the linked web page is Unix shell, which does the wildcard expansion before Ghostscript gets to see its own commandline. When Ghostscript gets to see it, the wildcard expansion has happened already.
You have to find a solution for your batch file where you first store your (expanded) *.pdf file names in a variable %mypdfs% and then do call gswin64c ... %mypdfs%.
you can't specify the wildcard from the command line, but you can make gswin32c run a command file.
as the 'command file' just requires switches to be separated by any amount of white space (space, tab, line break), and there is no limit on the size of the file, we can make a file that does what you need
echo -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=merged.pdf > files.gsx
dir *.pdf /b >> files.gsx
once this file files.gsx has been created, then you can make your file using
gswin32c #files.gsx
and all the files will be merged
I did the following to solve this:
1.) dir /B *.pdf > do.bat
2.) opened do.bat with notepad to replace \r\n with spaces
3.) inserted: c:\Programs\gs\gs9.07\bin\gswin64 -dNOPAUSE -sDEVICE=pdfwrite -sOutputFile=merged.pdf at the beginning
and then executed do.bat
Voilà
