I am trying to grep for a particular text (Do action on cell BL330) in a text file(sample.gz) which is searched in the content filtered by date+timestamp (2016-09-14 01:09:56,796 to 2016-09-15 04:10:29,719) on a remote machine and finally write the output into a output file on a local machine.
There seem to be several problems with your above code:
- shell variable assignment doesn't allow for spaces, so remove those around the "=" sign, and use quoting or escaping for the contents.
- don't expand (using the $ sign) the variable to be assigned to.
- within single quotes, no variable expansion is performed, so edit your sed and zgrep parameters. you may need to escape the $ sign within the ssh command line.
- I'm not sure zgrep makes sense after zcat | sed ... | .
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:

Hi,
1. Worked because sed prints range of lines and in those lines grep looks for " "Do action on cell BL330" and print 10 lines after matched pattern.
2. Grep first prints only 10 lines . Sed looks for range of lines from the output of grep , may be it is not present.
Check the output of grep.
Note : you can use
zgrep <string to look> sample.gz
Zcat is not required , IMHO.
zcat is identical to gunzip -c. (On some systems, zcat may be installed as gzcat to preserve the original link to compress.) zcat uncompresses either a list of files
on the command line or its standard input and writes the uncompressed data on standard output.
(c.f. man zcat) there's no compressed data any more, so using zgrep is overkill (although it may work as zgrep recognizes and works on uncompressed data).
2nd point: you have $do_action_on_cell_2=.... The $-sign is incorrect.
For the unterminated address regex error, we need to see what's going on. Try to run the command with the -vx options set to enable xtracing.
For the address range matching, the string you give for the starting address NEEDS to be found dot for dot, comma for comma, char for char, in the target file. Are you sure that's the case?
I am trying to add word in last of particular line.
the same command syntex is running on prompt. but in bash script give error."sed: -e expression #1, char 20: unterminated address regex"
Please help.
