With zsh:
Code:
zsh 4.3.4% ls
file1_11 file2_11 file3_11
zsh 4.3.4% autoload -U zmv
zsh 4.3.4% zmv '*' '${f/_11/}'
zsh 4.3.4% ls
file1 file2 file3
If you have rename:
Code:
zsh 4.3.4% ls
file1_11 file2_11 file3_11
zsh 4.3.4% type rename
rename is /usr/bin/rename
zsh 4.3.4% rename 's/_11//' *_11
zsh 4.3.4% ls
file1 file2 file3
Otherwise:
Code:
$ ls
file1_11 file2_11 file3_11
$ for f in *_11;do mv "$f" "${f%_11}";done
$ ls
file1 file2 file3
