Grep a number from a line in ksh - Shell Programming and Scripting

So close...

Code:

SIZE=`grep sizelimit myfile | sed 's/^.*sizelimit //' | awk '{print $1}'`

should work (NB. It allows for the arguments to be in a different order in the file).
There are other options that involve parsing the line (either in awk or shell), like:

Code:

SIZE=0
grep sizelimit myfile | while read s
do
  set -- $s
  while [ $# -gt 0 ]
  do
    case $1 in
      -sizelimit) SIZE=$2; break;;
      *) shift;;
    esac
  done
done
