Find (and delete) all files that do NOT contain certain patterns (PLURAL) in their name

Question

I'm looking for an easy way to find and delete all files in a directory and all its subdirectories that do NOT contain certain strings in their name.

I tried starting with the find command first:

find . -type f \! \( -name "TMP_TGL_2" -o -name "PRES_SFC_0" \)

But it doesn't seem to exclude the second string pattern. How can I accomplish this?

Answer 1

Try this:

find . -type f ! \( -name "*TMP_TGL_2*" -o -name "*PRES_SFC_0*" \)

The wildcards round the patterns will insure that they match files which contain those strings (otherwise they would only match files with names that are identical to the strings).
