'\r': command not found - .bashrc / .bash_profile
I am using cygwin and Windows7, the trick was NOT to put the set -o igncr into your .bashrc but put the whole SHELLOPTS into you environment variables under Windows. (So nothing with unix / cygwin...) I think it does not work from .bashrc because "the drops is already sucked"
as we would say in german. ;-)
So my SHELLOPTS looks like this
braceexpand:emacs:hashall:histexpand:history:igncr:interactive-comments:monitor
When all else fails in Cygwin...
Try running the dos2unix command on the file in question.
It might help when you see error messages like this:
-bash: '\r': command not found
Windows style newline characters can cause issues in Cygwin.
The dos2unix command modifies newline characters so they are Unix / Cygwin compatible.
CAUTION: the dos2unix command modifies files in place, so take precaution if necessary.
If you need to keep the original file, you should back it up first.
Note for Mac users: The dos2unix command does not exist on Mac OS X.
Check out this answer for a variety of solutions using different tools.
There is also a unix2dos command that does the reverse:
It modifies Unix newline characters so they're compatible with Windows tools.
If you open a file with Notepad and all the lines run together, try unix2dos filename.
For those who don't have dos2unix installed (and don't want to install it):
Remove trailing \r character that causes this error:
sed -i 's/\r$//' filename
Explanation:
Option -i is for in-place editing, we delete the trailing \r directly in the input file. Thus be careful to type the pattern correctly.
For WINDOWS (shell) users with Notepad++ (checked with v6.8.3) you can correct the specific file using the option
- Edit -> EOL conversion -> Unix/OSX format
And save your file again.
Edit: still works in v7.5.1 (Aug 29 2017)
Edit: Jan 3, 2022. As VSCode is mentioned several times. Go to settings in VSCode and type files.eol in the search field and set to \n (Unix format). Note that this changes this for your user or workspace for all files and it may not be what you want. YMMV.
