Shell Programming and Scripting

I have a directory that contains a number of history files for a process. Every file starts with the string "EVACK". FOr example

EVACK0101.000001
EVACK0102.095940
EVACKmmdd.hhmiss

I want to erase in the specific directory ONLY(no sub-directories) all EVACK files older then 90 days. I tested the find command using the following script.

find . -name "EVACK*" -ctime +90 -exec ls {} \;

and it found files in subdirectories that started with EVACK, which are older then 90 days and which I don't want deleted. Can anyone help me out with the correct command?

I looked in the Dummy answers and they all suggested find.

Check your version of the find command - see if it has a -prune option. That should work.

If you don't have that, then post your OS and version for more assistance or see this thread.

I think I got it.

find . \( ! -name . -prune \) -name "EVACK*" -type f -mtime +90 -exec ls {} \;
