How read file paths mentioned in a text file inside a Korn shell script?

Question

I am writing a script to read multiple log files and find lines with a specific string. However I am getting an error when trying to egrep/grep on the file.

I have a file that has the names of the log files to read (see below)

files.txt

./code_a.log
./code_b.log

log_analysis.ksh

#!/bin/ksh

platform=$1
lw_platform=$(echo "$platform" | tr '[:upper:]' '[:lower:]')
log_dir="/project/$lw_platform/logs/"
read_file="/user/LogAnalysis/files.txt"
out_file="/user/LogAnalysis/out3.txt"

echo $lw_platform
echo $log_dir

while -r line; do

    echo "Began: $line" >> $out_file

    cd ${log_dir}
    echo $(pwd)

    egrep -n 'ERROR:' $line >> $out_file

    echo "End: $line" >> $out_file

done < $read_file

CONSOLE OUTPUT

test 
/project/test/logs/ 
/project/test/logs 
.grep: 0652-033 Cannot open ./code_a.log

However I don't get this error if I run the same egrep command directly into the shell. Proves that I have the permissions to read the file.

I solved the issue by converting the file from dos line endings to UNIX format. I used the following command.

dos2unix files.txt
