Top Forums UNIX for Dummies Questions & Answers Ksh How to test if variable is numeric?? Post 302183651 by era on Wednesday 9th of April 2008 03:05:45 PM

Code:
case $zipcode in [0-9][0-9][0-9][0-9][0-9]) ;;
    *) echo "$myline"; echo "zipcode warning: $zipcode" >&2;;
esac

If it's five digits then it can't be bigger than 99999 or less than 00000, so that check seems superfluous. Also you seem to have a logic error there (it cannot be less than one and bigger than 99999). The check for bigger than 0 still needs to be done but it complicates things a bit so I didn't want to dilute this example with the handling of that.

how to set a variable to accept alpha-numeric characters?

I am working on a shell program that needs to accept alpha-numeric input (i.e., P00375); when I use a simple 'read' statement to read in the input (i.e., read LOG), I receive the message "p00375: bad number". How must I adjust my input statement to accept alpha-numerics? Thanks! Brent (3 Replies)
