Delete logs older than 60 days

i am using HP-UX OS......

delete logs older than 60 days

find  -mtime +60 |  grep -i '.*log' | xargs rm

-mtime is nt available in HP-UX, pls tell me other option ?

I very much doubt that. You are missing a pathname

find path-spec -mtime .....

-mtime is indeed available in HP-UX. By the way no need to use grep and pipe it to xargs rm, just do:-

find . -name '*.log' -mtime +60 -exec rm -f {} \;
