How about just using /usr/bin/test and get rid of the expr. AFAIK, it should whine if the input is not numeric, eg:
[EMAIL PROTECTED]:~$ i=4; test "$i" -ge -20 -a "$i" -lt 10 2> /dev/null; echo $? 0 [EMAIL PROTECTED]:~$ i=abc; test "$i" -ge -20 -a "$i" -lt 10 2> /dev/null; echo $? 2 [EMAIL PROTECTED]:~$ i=42; test "$i" -ge -20 -a "$i" -lt 10 2> /dev/null; echo $? 1 Or am I missing something here? -- x11-common have an important debconf bug https://launchpad.net/bugs/68267 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
