Remove all backup files in Linux using Shell script recursively

Question

How can I remove all backup files, i.e files ending with ~, recursively in a particular folder in Ubuntu?

A script in any programming language would do.

Answer 1

For one, you could use a simple find command:

find . -type f -name '*~' -delete

Answer 2

One way:

find folder -name '*~' -print0 | xargs -0 rm -f

Basically, look at "man find"

Answer 3

First off, what do you mean by recursively? Recursion is a convenient way to implement dome algorithms, but tends to be over-used - but some people also apply the term to searching a directory tree (which can be implemented by other means that recursion). If you simply want to delete all files matching a specific glob in a directory tree then....

find /base/directory/ -type f -iname '*~' -exec rm -f {}\;

(but you might want to experiment with find /base/directory/ -type f -iname '*~' -exec ls -l {}\; first).
