Looping through contents of a file and finding it in different directory

manpreet Best Answer 2 years ago

I need to compare the contents of a file located in dir A with actual files in different directory. ex- directory A has a file test.txt , Item mentioned in test.txt and not present in directory B should be highlighted. im doing something like this but not working.. it is only searching last word from the file test.txt

#!/bin/sh
IFS=$'\n' dirA=$1 dirB=$2 
for x in $(cat < "$1"); do base_name="${x##/}" 
set -- "$dirB"/"$base_name"* 
  if [ -e "$1" ]; then 
    for y; do 
   echo "$base_name found in B as ${y##*/}" done 
  else 
     echo "$x not found in B" fi done.

Using diff may do the trick

diff -crs Dir1 Dir2

It will show you if the files are existing, same or different

with a grep on filename might be what you are looking for
