Hi RudiC,

Thanks for the reply.

Regarding point 2 - it is just a typo error which i have corrected in this question.

The below commands when executed gives the followed result with -vx options:

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

Code:
+ ssh -q -o 'StrictHostKeyChecking no' deb011 'cd /intucell/data/logs/app; zcat sample.gz | tail -1| cut -d'\'' '\'' -f1-2;'
head -1 first_line_output.txt)
head -1 first_line_output.txt
++ head -1 first_line_output.txt
+ first_log_first_line='2016-09-14 01:46:56,438'


Not working case:
Code:
 ssh -q -o "StrictHostKeyChecking no" $server_id "cd /intucell/data/logs/app; zcat $first_line_log_file | sed -rne '/$first_line_date_time/,/$first_log_first_line/p'| zgrep -A10 -i '$do_action_on_cell_2';" >> ./output.log

Code:
+ ssh -q -o 'StrictHostKeyChecking no' deb011 'cd /intucell/data/logs/app; zcat sample.gz | zgrep -A10 -i '\''Do action on cell BLA330'\'' | sed -rne '\''/2016-09-14 01:09:56,796/,/2016-09-14 01:46:56,438/p'\'''
sed: -e expression #1, char 62: unterminated address regex

Let me know in case any other information is needed.

Hi,

change this to
Code:
sed -rne '/$first_line_date_time/,/$first_log_first_line/p'

double quotes. (as per post#1 these are variables)
Code:
sed -rne "/$first_line_date_time/,/$first_log_first_line/p"

There's no 62 chars in that regex; try setting the -vx options on the remote node, e.g. just before cd in the ssh command...

As per greet_sed changed sed expression to double quotes and output is below - NOK
Change is observed in the time stamp - space is highlighted:

Code:
 + ssh -q -o 'StrictHostKeyChecking no' deb011 'cd /intucell/data/logs/app; zcat sample.gz | sed -rne /2016-09-14' '01:09:56,796/,/2016-09-14' '01:46:56,438/p | grep -A10 -i '\''Do action on cell BLA330'\'';'
sed: -e expression #1, char 16: unterminated address regex

As per RudiC, added -vx before "cd in the code and below is the output:

Code:
 ssh -q -o "StrictHostKeyChecking no" $server_id -vx "cd /intucell/data/logs/app; zcat $first_line_log_file | sed -rne '/$first_line_date_time/,/$first_log_first_line/p' | grep -A10 -i '$do_action_on_cell_2';"

Output as below:
Code:
 + ssh -q -o 'StrictHostKeyChecking no' deb011 -vx 'cd /intucell/data/logs/app; sample.gz | sed -rne '\''/2016-09-14 01:09:56,796/,/2016-09-14 01:46:56,438/p'\'' | grep -A10 -i '\''Do action on cell BLA330'\'';'

From the output above, i feel the below part is suspicious:
Code:
 '/\033[36m2016-09-14 01:09:56,796/,/\033[32m2016-09-14 01:46:56,438/p'

Kindly guide

You have "ECMA-48 Set Graphics Rendition" control codes in your variable definition - that's how the 62 char is reached. I think, sed complains about opening but no closing square brackets.

Great, so any clue on how do i get out of this ?

Remove the control codes when/before assigning the variables.
