awk: cmd. line:1: fatal: cannot open file `-eq' for reading (No such file or directory)

Im quite new to bash scripting and I tried checking through the previous examples of this error but I still dont undertand why this isnt working

Here is the snippit of code throwing up the error:

#!/bin/bash

function group_check(){
    if [[getent group | awk -F":" '{print$1}' -eq $1 ]] ; then
            echo "The user exists!"
    else
            echo "The user doesn't exist!"
    fi
}

group_check tim
group_check tam

Hopefully someone cant point out where im going wrong or perhaps even suggest a better way of doing this, but I would quite like to understand where im going wrong.

Thanks

If you want to compare output of a command to a number, you have to enclose the command into $(...) to capture its output:

if [[ $( getent group | awk -F":" '{print$1}' ) -eq $1 ]] ; then

Note that the space after [[ isn't optional.

Also note that -eq compares numbers, you should use == for string comparison.
