Hi RudiC, Thanks for quick reply and correcting the code format.

- Space in assignment of variable was a typo error, I have corrected it now. The variables given are only for providing more information to my question on the parameters used.

- I did not understand the 2nd point mentioned.

- There is a double quote in the code pasted, which i believe is taking care of variable expansion. Also below is another example which works perfectly fine and fetches me desired output:

Code:
ssh -q -o "StrictHostKeyChecking no" $server_id "cd /intucell/data/logs/app; zcat $first_line_log_file | tail -1| cut -d' ' -f1-2;"

- I will make changes to see if
Code:
 zcat | zgrep

and then
Code:
 sed

works or not.

---------- Post updated at 08:42 PM ---------- Previous update was at 08:18 PM ----------

Just a quick update:

I have tried the below two options on remote server (hostname) directly on the file and results as below

1. zcat | sed | zgrep -> This works fine.

Code:
zcat sample.gz | sed -rne '/2016-09-14 01:09:56,796/,/2016-09-14 01:46:56,438/p' | zgrep -A10 -i "Do action on cell BL330"

2. zcat | zgrep | sed -> This does not print any output

Code:
zcat sample.gz | zgrep -A10 -i "Do action on cell BL330" | sed -rne '/2016-09-14 01:09:56,796/,/2016-09-14  01:46:56,438/p'

I suspect that the problem is with sed expression and escaping the correct characters.
Please have a look and suggest.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep.  If no file is speci-
       fied, then the standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed	if  necessary  and
       fed to grep.

       If  zgrep  is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, zgrep uses
       it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	zgrep string files
	   for csh: (setenv GREP fgrep; zgrep string files)
