getting current directory in linux for argument

I’m learning Linux scripting and trying to set up a function that finds all files in the current directory. I know I could use ls but I’m wondering if there is a way to get the current directory as a command and pass it to an argument.

#!/bin/bash


check_file() {
for f in $1: 
do
    echo $f
done
}

check_file pwd

This just prints out pwd:, which obviously isn’t it.

Answer

PWD variable does exactly what you want. So just replace pwd with $PWD and you are done
