/bin/bash^M: bad interpreter

Thu, 23 Nov 2023 00:00:00 -0500

Bash scripts are very sensitive to line endings which can cause some portability issues between windows and unix-like systems (depending on how the text editor encodes line breaks). If you would like to see the invisible characters that are making your life confusing simply type:

cat -v <FILE>

The easiest solution to this issue is a simple sed replace line:

sed -i -e 's/\r$//' <FILE>
