Running a shell script through Cygwin on Windows

Solution 1:

Sure. On my (pretty vanilla) Cygwin setup, bash is in c:\cygwin\bin so I can run a bash script (say testit.sh) from a Windows batch file using a command like:

C:\cygwin\bin\bash testit.sh

... which can be included in a .bat file as easily as it can be typed at the command line, and with the same effect.

Solution 2:

One more thing - if You edited the shell script in some Windows text editor, which produces the \r\n line-endings, cygwin's bash wouldn't accept those \r. Just run dos2unix testit.sh before executing the script:

C:\cygwin\bin\dos2unix testit.sh
C:\cygwin\bin\bash testit.sh

Solution 3:

If you have access to the Notepad++ editor on Windows there is a feature that allows you to easily get around this problem:

1. Open the file that's giving the error in Notepad++.
2. Go under the "Edit" Menu and choose "EOL Conversion"
3. There is an option there for "UNIX/OSX Format." Choose that option.
4. Re-save the file.

I did this and it solved my problems.

Hope this helps!

Solution 4:

Just wanted to add that you can do this to apply dos2unix fix for all files under a directory, as it saved me heaps of time when we had to 'fix' a bunch of our scripts.

find . -type f -exec dos2unix.exe {} \;

I'd do it as a comment to Roman's answer, but I don't have access to commenting yet.
