Have a look at this
Code:
$ cat mad.ksh #! /bin/ksh [[ -z "$1" ]] && echo "I cant work without an input" && exit 1 INPUT="$@" [[ "$INPUT" == ?(+|-)+([0-9]) ]] && echo "$INPUT is numeric" && exit 0 [[ "$INPUT" == +([a-zA-Z]) ]] && echo "$INPUT is character" && exit 0 [[ "$INPUT" == *([0-9]|[a-zA-Z])* ]] && echo "$INPUT is alpha-numeric" && exit 0 Code:
$ ./mad.ksh 123 123 is numeric $ ./mad.ksh abc abc is character $ ./mad.ksh abc123 abc123 is alpha-numeric -vino Last edited by vino; 09-21-2005 at 03:30 AM. Reason: Enhanced to check for +ve and -ve numbers.
