How do I compare file names in two directories in shell script?

Question

Right now, this is what my code looks like:

#!/bin/bash

Dir1=$1
Dir2=$2

for file1 in $Dir1/*; do
    for file2 in $Dir2/*; do
        if [[ $file1 == $file2 ]]         


        

Answer 1

If you want to know what's common to two directories then this is another way with much less coding.

#!/bin/bash

comm -12 <(ls -F $1) <(ls -F $2)

See man comm for more information about the comm utility.
