gzip files 3 at a time

[Parttimer]

How do I --
Using a ksh script - Process a list of files and gzip or compress them. Say 15 files. And process 3 at a time (to limit CPU usage). Then process the next 3 until all done.

Try something like this:

typeset -i i=0
while read file; do
  gzip "$file" &
  i=$((i+1))
  [ $i -eq 3 ] && i=0 && wait
done <path/to/ListOfFiles
wait

Hope This Help
