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

#!/bin/sh

manifest=$1
topdir=$2

while IFS= read -r name; do
 pathname="$topdir/$name"

 if [ -e "$pathname" ]; then
 printf 'Found: %sn' "$pathname" >&2
 else
 printf 'Not found: %sn' "$pathname" >&2
 fi
done <"$manifest"

This script takes a manifest file as its first command line argument, and some directory path as its second argument.

It reads lines from the manifest and tests to see if the pathnames corresponding to those lines exists under the given directory.

Would you only want to test the base name of each name read from the file, then use

#!/bin/sh

manifest=$1
topdir=$2

while IFS= read -r name; do
 pathname="$topdir/$( basename "$name" )"

 if [ -e "$pathname" ]; then
 printf 'Found: %sn' "$pathname" >&2
 else
 printf 'Not found: %sn' "$pathname" >&2
 fi
done <"$manifest"
