shell script, reading and resetting local variables

b888c · #1 (**permalink**) 08-20-2001

Hello,

I have a problem with trying to run a shell script that reads in user input, validates, and sets to a 'default' value if the input is not valid. I cannot get the portion of resetting to a default value to work. These lines are skipped, and the
value of x is still whatever the user entered initially. Is it possible that the first x variable is not the same as the x in 'setx=10' line?

simpled version of the script

#!/bin/sh
#
echo "Enter x"
read x
echo "You entered $x"
#
# lines to validate here...
# ....
#
# I cannot get the following lines to work
set x=10
echo "x reset to $x"

Instead of "set x=10", use "x=10" or "set x 10", you will have the right output.
