'\r': command not found - .bashrc / .bash_profile [duplicate]
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.
