Answer 1

I had to rename all folders inside a given folder. Each folder name had some text inside round braces. The following command removed the round braces from all folder names:

rename 's/(.+)//' *

Answer 2

I don't know whether it's just a typo when you typed it here, but that "rename" command should work if:

1. you leave off the "-n" and
2. you quote the substitution with regular single-quotes and not back-quotes

The "-n" tells it to not really do anything. The back-quotes are just wrong (they mean something but not what you want here).

Answer 3

for DIR in \#*/
do
     echo mv "$DIR" "${DIR/#\#/}"
done

Answer 4

Just use

$ rename 's/^#//' *

use -n just to check that what you think it would happen really happens. In you example you have the clue about the wrong quotes used (backticks) in the error message

 -bash: s/#//g: No such file or directory

bash is trying to execute a command named s/#//g.

No that using g (global) and not anchoring the regular expression you will replace any #, not just the one in the first position.

Answer 5

The problem is that you use backticks (`). You should use normal quotes:

rename -n 's/#//g' *
