how do i remove a word from multiple file names?


hey all lets say i have some files with names like these:

Quote:
file.WordiWantToRemove.part1.rar
file.WordiWantToRemove.part2.rar
file.WordiWantToRemove.part3.rar
how would i go about removing the 'word' in the file names (or replace it) this is what i have so far but the quotes are wrong... ???

Code:
for files in *.rar; do mv “$files” `echo $files | tr ‘oldword‘ ‘newword’`; done

no need to use external commands. with bash
Code:
for file in *.rar; do echo mv "$file" "${file/Word/NewWord}"; done

1) useless use of ls in the for loop. Also, it breaks on files with spaces. Use shell expansion instead.
2) using "|" and calling external commands creates extra overheads. The shell provides simple substitution, so try to use it whenever possible

I have always done this with sed, like ramram did above. Yet again, something new learned today! And another reason bash is good

Thanks Ghostdog,

You have many answers, so I just thought I'd point out that the primary problem with your original attempt is that tr only replaces single characters.
