I got try the following perl script. Unfortunately, it can't give my desired output result
Code:
cat file_1
>sample_1
FKGJGPOPOPOQA
ASDADWEEWERE
ASDAWEWQWRW
ASDASDASDASDD
cat file_2
>sample_1
DRTOWPFPOPOQA
ASDADWEEASDF
ASDADRTYWRW
ASDASDASDASDD
perl -e ' ($file1, $file2) = @ARGV; $printed = 0; open F2, $file2; while (<F2>) { $h2{$_}++ }; $count2 = $.; open F1, $file1; while (<F1>) { if (! $h2{$_}) { print $_; $printed++; } } $count1 = $.; warn "\nRead $count1 lines from $file1 and $count2 lines from $file2.\nPrinted $printed lines found in $file1 but not in $file2\n\n" ' file_1 file_2 > file_3
cat file_3
FKGJGPOPOPOQA
ASDADWEEWERE
ASDAWEWQWRW
Desired output file content:
Code:
FKGJGPO
WERE
WEWQ
The perl command that I used print out the whole content instead of just print out the specific special content that I interested in file_1
Thanks a lot for any advice.

diff3
DIFF3(1) General Commands Manual DIFF3(1)NAME
diff3 - 3-way differential file comparison
SYNOPSIS
diff3 [ -exEX3 ] file1 file2 file3
DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes:
==== all three files differ
====1 file1 is different
====2 file2 is different
====3 file3 is different
The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways:
f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3.
f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1.
The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of
the lower-numbered file is suppressed.
Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e.
the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ====
(====3). The following command will apply the resulting script to `file1'.
(cat script; echo '1,$p') | ed - file1
The -E and -X are similar to -e and -x, respectively, but treat overlapping changes (i.e., changes that would be flagged with ==== in the
normal listing) differently. The overlapping lines from both files will be inserted by the edit script, bracketed by "<<<<<<" and ">>>>>>"
lines.
For example, suppose lines 7-8 are changed in both file1 and file2. Applying the edit script generated by the command
"diff3 -E file1 file2 file3"
to file1 results in the file:
lines 1-6
of file1
<<<<<<< file1
lines 7-8
of file1
=======
lines 7-8
of file3
>>>>>>> file3
rest of file1
The -E option is used by RCS merge(1) to insure that overlapping changes in the merged files are preserved and brought to someone's atten-
tion.
FILES
/tmp/d3?????
/usr/libexec/diff3
SEE ALSO diff(1)BUGS
Text lines that consist of a single `.' will defeat -e.
