In Rails sometimes I need to rename several directories and files, e.g.:


I've exhausted looking up solutions. Does anyone know of a simple command line tool that I can install? E.g. mvall . person user.

Look at the Related questions on the right column. There are lot of answers to this question. – alecail Oct 24 '12 at 20:10

I'm sure there are better ways to do it, but here's my implementation.

$ old=person; new=user; for i in $(find ./ -name "*$old*"); do mv $i $(echo $i | sed 's/'$old'/'$new'/g'); done

All the tools are in bash, so nothing needs to be installed.

You could also use find to execute your changes (rather than just locate the targets), It probably depends on whether you're more comfortable with find or bash. – Dominic Cronin Oct 24 '12 at 21:00
@Rusty: for i in $(find . …) will fail if there are filenames that contain spaces. And you don’t need to say “./”. – Scott Oct 24 '12 at 22:33
@Dominic: Is find guaranteed to behave sanely if you rename directories while it is traversing the directory tree? – Scott Oct 24 '12 at 22:33
@Scott - good question. Don't know the answer – Dominic Cronin Oct 24 '12 at 22:47
