First, probably just a copy problem: #! must be the first two chars of the files, there can be no lines before it!
userid= here something is missing. You are not allowed to use space before and after = sign, and also you would need to assign the return of awk. It has different syntax:
userid=$(awk ... )
Probably it will return more values, the following if may fail. Also you would use " around and space after and before [ (also would prefer [[ )
if [[ "$userid" > 1 ]]
- You did not copy/paste my solution correctly (missing _)
- Storing the output of a command isn't syntactically correct. The correct way:
Code:
variable=$( command )
- Spaces are important, you are missing them here:
Code:
[$userid>1 ]
The above script can be re-written to:
Code:
#!/usr/bin/bash
echo "Name: "
echo "Test criteria: All user ids are unique"
userid=$( awk -F: '_[$3]++ == "1" { print $3 }' /etc/passwd )
if [[ $userid ]]
then
echo "Exception: YES"
for i in $userid
do
grep $i /etc/passwd
done
else
echo "Exception:NO"
fi
