How to delete recursevly in unix, specific filetypes?

Question

I want to delete only *.pdf files in multiple nested categories.

How can I do that?

Answer 1

one way is by using the find command with the -exec or -delete options.

read the find man page for details, but as an example to list pdfs in the /tmp/foo/ directory recursively, you would do:

find /tmp/foo/. -type f -name "*.pdf" -exec echo {} ';'

to delete them, simply change "echo" to "rm"

Answer 2

Use the "find" command eith the exec option
find . -name "*.pdf" -exec rm {}\;

Do a "man find" to check the syntax before you do.
