I have a file containing paths to certain other files.
Now I want to read out this file line by line and call a function on each path specified.
#!/bin/bash
mkdir dest
while IFS='' read -r line || [[ -n "$line" ]]; do
mv "$line" dest/
done < input_file
and my input file looks like this:
./data/f1
./data/f2
./data/f3
But I get this error:
mv: cannot stat './data/f3'$'r': No such file or directory
mv: cannot stat './data/f3'$'r': No such file or directory
mv: cannot stat './data/f3'$'r': No such file or directory
I couldn't figure out what these special symbols in the end mean.

Also, if you fixinput_fileto be a proper POSIX text file, you can get rid of the|| [ -n "$line" ]]hack.
