Script to list files not present in audio.txt file

I am having following folder structure.

/root/audios/pop
/root/audios/jazz
/root/audios/rock

Inside those pop, jazz, rock folders there are following files,
p1.ul, p2.ul, p3.ul, j1.ul, j2.ul, j3.ul, r1.ul, r2.ul, r3.ul

And I have a file named as "audio.txt" in the path /root/audios, which is having the following contents,
p1.ul
p2.ul
j1.ul
j2.ul
r1.ul
r2.ul

I have the following script named as script1.sh to check and display all the files present inside the folders when I pass "audio.txt" as a parameter.

Code:
#! /bin/sh
var = `cat $1`
for i in $var; do
find . -name "$i" -exec echo "$i" \;
end

$bash script1.sh audio.txt

Could you please modify the code for displaying the files that are not present.
i.e. it should display
p3.ul
j3.ul
r3.ul

Thanks in advance.

I don't thinjk the script you gave us will work. At all. However try this to find those missing:
Code:
#! /bin/sh                          

while read i 
do                  
  for j in p1.ul p2.ul j1.ul j2.ul r1.ul r2.ul  
  do
     [ ! -f ${i}/${j} ]  && echo "${i}/${j} is missing"   
  done
done < /root/audios/audio.txt
end

  done
done < /root/audios/audio.txt
end

But hereyou have used
Quote:
for j in p1.ul p2.ul j1.ul j2.ul r1.ul r2.ul
Instead of hardcoding the filenames, is it possible to read them one by one from audio.txt and loop rather? Because there are many more files then I mentioned and its hard to hardcode each one of them..

The following (untested) may be sufficient for your needs:
Code:
find /root/audios -type f -name '*.ul' | grep -vFf /root/audios/audio.txt

My bad, I framed the question little wrongly. I need the reverse scenario.

And little correction below as well,

Inside those pop, jazz, rock folders there are following files,
p1.ul, p2.ul, j1.ul, j2.ul, r1.ul, r2.ul

And I have a file named as "audio.txt" in the path /root/audios, which is having the following contents,
p1.ul
p2.ul
p3.ul
j1.ul
j2.ul
j3.ul
r1.ul
r2.ul
r3.ul

So I need to display p3.ul, j3.ul, r3.ul from audio.txt file which are not present in the those folders.

Thanks !

If your shell supports process substitution:
Code:
grep -vFf <(find /root/audios -type f -name '*.ul' | sed 's/.*\///') /root/audios/audio.txt

Alternatively, you can use a temporary file:
Code:
ul_found=$TMPDIR/ul_found
find /root/audios -type f -name '*.ul' | sed 's/.*\///' > "$ul_found"
grep -vFf "$ul_found" /root/audios/audio.txt
rm "$ul_found"

If you intend to run multiple instances of the temp file version, you'll need a more robust scheme (using mktemp would be much better).

Another approach would be to take a sorted list of the basenames of the pathnames generated by find and use comm(1) to compare it against a sorted audio.txt.

Try this:
Code:
find /root/audios -name "*.ul" -exec basename {} \; > Found_Files.txt
egrep -v -f Found_Files.txt audio.txt
