hi, i am a newbie in shell. i am using c shell.
If you want to write a script, don't use csh.
if i can chose, i'd use python. yes, ...maybe i can chose.
it works, thanks.
say convert a argument to int.
if it is not a int , some flag or message should be got.
how to do so in a neat way?
A simple test for a numeric argument, in a standard shell is:
case $n in
*[!0-9]*) printf "%s\n" "Not a number" ;;
esac
