I with help of wolfmilkporc found a way to remove the control color codes.

Code:
first_line_date_time=$(echo $first_line_date_time | perl -pe 's/\e\[[\d;]*m//g;')
                                     and
                                    first_log_first_line=$(echo $first_log_first_line | perl -pe 's/\e\[[\d;]*m//g;')

Acknowledgement: Got the Perl regex from the source of the module Term::ANSIColor, see here ("colorstrip"):
lib/Term/ANSIColor.pm - metacpan.org
Special thanks to RudiC, wolfmilkporc, Kurt Starsinic and greet_sed.

Where and how did you assign the variables in the first place?

Hi RudiC,

The variable is assigned with the date+time of the first line from the text file which contains the content redirected using zgrep.

example:
Code:
 sample.gz:2016-09-14 01:09:56,796 [4665:ActionService:22:execute_changes:INFO] Action 126543 was created and sent to execution

I have removed the color escape characters using the below perl regex and the issue is resolved.

Code:
first_log_last_line=$(echo $first_log_first_line | perl -pe 's/\e\[[\d;]*m//g;')


However, I have a new requirement - explained as below:

I have to sort only the lines containing the date+time.
Sample text file as below:
Code:
========== server_1 ==========
sample1.gz: 2016-09-14 02:55:30,799
sample2.gz: 2016-09-14 01:09:56,796
sample2.gz: 2016-09-14 01:09:57,927
========== server_2 ==========
========== server_3 ==========
========== server_1 ==========
sample1.gz: 2016-09-14 02:55:31,250
sample1.gz: 2016-09-14 02:55:31,777

Desired output:
Code:
========== server_1 ==========
sample2.gz: 2016-09-14 01:09:56,796
sample2.gz: 2016-09-14 01:09:57,927
sample1.gz: 2016-09-14 02:55:30,799
sample1.gz: 2016-09-14 02:55:31,250
sample1.gz: 2016-09-14 02:55:31,777
========== server_2 ==========
========== server_3 ==========

Please suggest how this can be achieved.

So - you have coloured output in the files? Can't they be produced without colour information?

Do you need the server_n info in the sorted output? If not, try
Code:
sort -uk2 file4
sample2.gz: 2016-09-14 01:09:56,796
sample2.gz: 2016-09-14 01:09:57,927
sample1.gz: 2016-09-14 02:55:30,799
sample1.gz: 2016-09-14 02:55:31,250
sample1.gz: 2016-09-14 02:55:31,777
========== server_1 ==========
========== server_2 ==========
========== server_3 ==========

Hi RudiC,

I have used the perl regex to avoid the colored output.

Yes, I would need the server_n output as well.
The logs will be only for a single server and on sorting i need the information which server these logs belongs to as well.

Try
Code:
awk '/^====/ {PRF = $2 = "0"$2} {print PRF, $0}' file | sort -uk1,1 -k3 | awk '{sub ($1 FS, _); sub (/^0/, _, $2)}1'
========== server_1 ==========
sample2.gz: 2016-09-14 01:09:56,796
sample2.gz: 2016-09-14 01:09:57,927
sample1.gz: 2016-09-14 02:55:30,799
sample1.gz: 2016-09-14 02:55:31,250
sample1.gz: 2016-09-14 02:55:31,777
========== server_2 ==========
========== server_3 ==========
