I'm new to MSYS2 and have previously only used the Windows Command Prompt. Here I'm facing the problem, that a path copied from the Windows Explorer entered there with copy and paste can't be resolved. You must then manually replace all the \ with / which is very tedious. Is there a better solution that saves a lot of time?

I built a quite large PDF using LaTeX with the lualatex compiler (I need that one because of specific fonts) and now want to shrink the PDF with ps2pdf, following this instruction (the answer with the second-most votes, since gs is not recognized as a command line tool on my computer). My command looks like this:
ps2pdf -dPDFSETTINGS=/ebook -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -q -sOutputFile=output.pdf input.pdf
I get this error message:
MiKTeX GPL Ghostscript 9.25: Device 'pdfwrite' requires an output file but no file was specified.
**** Unable to open the initial device, quitting.
I definitely made sure that the file exists, I tried it using as *.ps file as input, gave the full path, once with and without double-quotes (Windows system), yet nothing worked. Strangely enough, just running ps2pdf ouput.pdf input.ps works, but produces an even larger PDF. What am I missing?
The file that can't be opened is the output file, so if it exists, that would be a potential problem. If 'something else' has the output file open then it won't be possible to write to it.
You appear to be running a non-standard version of Ghostscript, judging by the startup banner, if I were you I would install and use a standard version of Ghostscript, even if you have to build it yourself.
It's odd that 'ps2pdf' which is just a script to run Ghostscript would work, whereas a simple 'gs' would not. I personally would not use the script. Try and find the Ghostscript executable and run that directly.
I'd drop the -q (quiet) switch as well, at least while trying to solve a problem, suppressing messages could be hiding something useful.
Oh I see, you are actually using Windows. Well, the executable on Windows isn't called 'gs', it's called gswin followed by either 32 or 64 for the word size and then c if it's the command line (as opposed to windowed) version. So you want one of gswin32, gswin32c, gswin64 or gswin64c. Note that the Ghostscript installer doesn't add the installation directory to the $PATH environment variable so if you just open a Windows command shell and type 'gswin32c' it won't be found. You need to either add the isntall directory to the $PATH or supply a full path to the executable.
I'd personally use the vanilla Windows binary rather than a modified version supplied under MingW or whatever Linux shell you are using. It's also conceivable that this is causing your problem writing to the output file, if the directory is unavailable, or read-only, to the shell.
I recently installed WSL version 2 according to the instruction. Everything work greatly. But I notice that the folder /mnt/c is not available any more.
I understand the new WSL using vhdx as file system which gives us better FS performance, but I could not find a way to access files in Windows.
I also tried to check the wsl --help but I could not find anything helpful.
Any suggestions?
After read more, I notice that WSL 2 is actually an optimized VM on Windows 10, which means the running WSL 2 has no idea about where it self. Seems there should be a way to pass some Windows folders while launch it. Haven't figured out how.....
By default, the command prompt in WSL is located at C:\Users\username. WSL considers this /home/user but you can can reference any directory on your Windows machine by starting at the root directory with /../../.
Here is an example command: find "/../../mnt/c/anyFolder/subfolder" -name "test" -type d
I am trying to download a bunch of PDF's from the federal reserve archives but I have to click on a link and then view the PDF before I can download. Is there a way to automate this?
Example: https://fraser.stlouisfed.org/title/5170#521653 is a link to speeches and then you have to click the title, then view pdf, then the actual download button.
All of the remote .pdf files follow the path format:
https://fraser.stlouisfed.org/files/docs/historical/frbatl/speeches/guynn_xxxxxxxx.pdf
where each x is a placeholder for a digit.
So, yes, it's very easy to download a bunch of these PDFs in one go using the command-line in Terminal or whatever shell program you have access to.
If you're in a *nix-based operating system (including MacOS), that's good because your shell probably already has a command utility called curl installed. Windows may have it too, I'm not sure; I don't use Windows.
If you're using Windows, you'll have to make some tweaks to the code below, because the folder structures and file naming conventions are different, so the first couple of commands won't work.
But, if you're happy to proceed, open up a Terminal window, and type in this command to create a new directory in your Downloads folder, into which the .pdf files will be downloaded:
mkdir ~/Downloads/FRASER_PDFs; cd ~/Downloads/FRASER_PDFs
Hit Enter. Next, If there's no error, copy-n-paste this long command and then hit Enter:
curl --url \
"https://fraser.stlouisfed.org/files/docs/historical/frbatl/speeches/guynn_{"$(curl \
https://fraser.stlouisfed.org/title/5170#521653 --silent \
| egrep -io -e '/files/docs/historical/frbatl/speeches/guynn_\d+\.pdf' \
| egrep -o -e '\d+' | tr '\n' ',')"}.pdf" -O --remote-name-all
You can see this uses the URL you supplied in your question, from which that command retrieves all the .pdf links. If you need to do the same with other similar pages, provided they all use the same URL format, you can just substitute 5170#521653 with whatever page reference contains another list of .pdfs.
I'm trying to change the permissions of some files on windows to 'rw' only for owner user. As you can see it says that the files are changed to 'rw-------'. When I list the files again nothing is changed.
chmod is just emulated in Windows for Cygwin and MSys.
The best way to solve the issue is to use icacls to change permissions.
The command line could be found in official doc from Microsoft, like here
Note that the chmod status in Msys or Cygwin might not be correct. For example, this is what I get in Msys after removing all accesss to "toto.txt"
I am getting started with Meteorjs. I'm a windows user so I downloaded the windows installer package Release 0.7.0.1-win2. I use gitbash for my command line interface and can't get it to recognize meteor. I get the error "sh.exe": meteor: command not found". It works fine in windows command line but I prefer gitbash.
How do I get meteor to work with gitbash?
I have the perfect answer for you since I literally just solved the issue myself.
First of all make sure meteor works in the default windows command prompt. Next open git bash and check if the following command works:
cmd //c meteor
This runs the command meteor as if you were in the command prompt.
Next step is to set up an alias in git bash so you don't have to type that out each time.
Open git bash and enter the following:
vim ~/.bashrc
this will open/create the bashrc file in VIM, press i to insert and type the following:
alias meteor="cmd //c meteor"
Save and exit vim by first pressing the Esc key then press the ":" key. Now you should be able to enter commands in VIM. Type "wq" and press enter which will write into your .bashrc file and exit vim.
Almost there! Now that you are back in git bash, all you need to do is point to your .bashrc file by entering the following:
source ~/.bashrc
Now you will be able to run meteor commands straight from git bash! Hope that helped!
Here's the fix:
The problem is because of .bat files not being handled properly by
MinGW
Go to this directory - C:\Users[your username]\AppData\Local\.meteor
You should see a meteor.bat file there. Create a new file called "meteor" (without any extension and ""). Open it with notepad and paste the following:
#!/bin/sh
cmd //c "$0.bat" "$#"
save the file and now run git bash. You should be able to use meteor command in git bash.
Details
To run a *.bat command from MinGW's MSYS shell, you must redirect the execution to cmd.exe, thus:
cmd //c foo.bat [args ...]
The foo.bat command file must be in a directory within $PATH, (or you must specify the full path name ... using slashes, not backslashes unless you use two of them for each path name separator). Also, note the double slash to inform cmd.exe that you are using its /C option, (since it doesn't accept the -c form preferred by the MSYS shell.
If you'd like to make the foo.bat file directly executable from the MSYS shell, you may create a two line Bourne shell wrapper script called simply foo alongside it, (in the same directory as foo.bat), thus:
#!/bin/sh
cmd //c "$0.bat" "$#"
(so in your case, you'd create script file meteor alongside meteor.bat).
In fact, since this wrapper script is entirely generic, provided your file system supports hard file links, (as NTFS does for files on one single disk partition), you may create one wrapper script, and link it to as many command file names as you have *.bat files you'd like to invoke in this manner; (hint: use the MSYS ln command to link the files).

It shouldn't be too hard - you just need to make sure that the meteor.bat file is in your executable. Check with echo $PATH from the bash console if it is already there.
For me, the meteor 0.7.0.1-win installer appended meteor's folder to the path automatically. However, you can add it manually with:
export PATH=$PATH:/path/to/user/folder/AppData/Local/.meteor
(On CygWin my user folder is at /cygdrive/c/Users/adam - I'm not sure what the equivalent path would be on git bash).
If you like, append that line to your ~/.profile to make sure meteor gets added to the path when the console opens.
Finally, on Windows the executable file is meteor.bat. I made a symbolic link to the filename meteor, just so I wouldn't have to type the .bat:
cd /path/to/user/folder/AppData/Local/.meteor
ln -s meteor.bat meteor.
Please have a look at the issue https://github.com/sdarnell/meteor/issues/18
I would suggest maybe creating a trivial wrapper script or alias that invokes LaunchMeteor.exe with the original arguments.
After more research on google I see that there isn't an implemented way to do this yet. The guys at meteor are working on it and accepting pull requests if you have a solution. The conclusion I came to is to use Vagrant and virtualbox to set up a ubuntu vm for meteor development. You can find info at this site: http://win.meteor.com/ on how to install virtual machines and provision to work with meteor.
