String comparison issue in bash script

String comparison issue in bash script

I wrote the bellow script the purpose of the script is to find all files
that start with foo and are no older 3 days sort them then compare them
against the list of files in the list file. And to repot only files that
are missing. The problem with my script is that it doesn't not take in to
account a missing file ie see below example Let's say my file called list
contains foo1, foo2, foo3, foo4, foo5 but in the event that one file files
is missing the string comparison is off. Ie if file foo4 is missing when
the script is ran foo5 would be compared foo4
Hope that makes sense
enter
#!/bin/bash
Set –x
Find ~/test99 –name "foo*" –mtime -3 –print>report
Sort report –o report;
Cat report|cut -c 22-25>report1;
while read comp1<&3 && read comp2<&4
do
if [[ $comp1 = comp2 ]]; then
echo "file not found" >/dev/null
else
echo "$comp1 not found"
fi
done 3<report1 4<list
