RudiC, I tried to write below code, but not able write the logic how to check below columns with header file columns.

Code:
TRX #    TYPE    REF #    Source Piece Code    Destination Piece Code

Code:
cd $MOUNT_DIR 
for file in $(ls ${MOUNT_DIR}/Test*.txt)
do
    file_name=$(basename $file)
    echo $name
    chmod -R 777 $MOUNT_DIR$name
    match_header=awk NR==1 $file_name
    echo "the header file from the input file is" $match_header
    
    if [ comm $match_header =] ** not able the script how to compare the header columns to mentioned columns **
    then
        echo $name:"Header file mismatch, terminate the flow " >> $JOB_LOG
        exit 1
    else
        echo $name:"Header file match, We can process this file " >> $JOB_LOG
    fi
done

rovf, Sorry for confusion. it was txt file (I have edited the post).

Desired columns (A): TRX # TYPE REF # Source Piece Code

columns we get from header file (B): TRX # TYPE *** # Source Piece Code

if columns from header file doesn't matches to Desired columns then it need to through terminate exit 1. else process the file

Test::Inline::Content::Legacy(3pm)			User Contributed Perl Documentation			Test::Inline::Content::Legacy(3pm)

NAME
Test::Inline::Content::Legacy - Test::Inline 2 Content Handler for legacy functions SYNOPSIS
Custom script content generation using Test::Inline 2.000+ with a custom generator functions my $header = "...."; my $function = sub { my $Object = shift; my $Script = shift; return $header . $Script->merged_content; }; my $Inline = Test::Inline->new( ... file_content => $function, ); Migrating this same code to Test::Inline 2.100+ ContentHandler objects my $header = "...."; my $function = sub { my $Object = shift; my $Script = shift; return $header . $Script->merged_content; }; my $ContentHandler = Test::Inline::Content::Legacy->new( $function ); my $Inline = Test::Inline->new( ... ContentHandler => $ContentHandler, ); DESCRIPTION
This class exists to provide a migration path for anyone using the custom script generators in Test::Inline via the "file_content" param. The synopsis above pretty much says all you need to know. METHODS
new $CODE_ref The "new" constructor for "Test::Inline::Content::Legacy" takes a single parameter of a "CODE" reference, as you would have previously provided directly to "file_content". Returns a new "Test::Inline::Content::Legacy" object, or "undef" if not passed a "CODE" reference. coderef The "coderef" accessor returns the "CODE" reference for the object process $Inline $Script The "process" method works with the legacy function by passing the Test::Inline and Test::Inline::Script arguments straight through to the legacy function, and returning it's result as the return value.
