Integer check (again)...
I have search the forum for an easier way to write this code. I have two separate 'if' to do this and it works but am wondering if someone knows a quick way to combine them. I want anything between 1 and 100 but not '01' or '005', '0010', etc. Code:
if [[ $myvar != +([0-9]) ]] || [[ $myvar -le 0 || $myvar -gt 100 ]]; then echo "Try again" fi After that check, I do another check with a grep to make sure it doesn't start with a zero (so this is the 'else' block of the above code): Code:
if echo $myvar | grep '^[1-9][0-9]*'; then echo "Cool" fi Any thoughts? |
