Increment userid in file
Hello,
does anyone know how to increment a userid(number) written in any scripting language that works on a shell?
For example:
I have a HTML file in this format:
userid:
name:
telephone:
Every time I execute my script it adds the same fields, except with the userid incremented. Like this:
userid: 0
userid: 1
userid: 2
My script isn't always running, so the variable userid should be saved somewhere, so it won't reset and starts with userid 0 once I re-run the script.
Thanks.
