What I would ideally like to do is perform a grep on all of the files, and if any of the search parameters are found, output both the filename and the line containing the parameter found. This is the default behaviour for grep, is it not? If no matches are found, I want to output an appropriate message.
I was thinking of something along the lines of:
Running that line of code twice seems wasteful, though. Can this be done without the duplication?
Hi all,
I am trying to zgrep / grep list of files so that it displays only the matching filename:line number and does not display the whole line, like:
(echo "1.txt";echo "2.txt") | xargs zgrep -no STRING
If I use -o option, it displays the matching STRING and if not used, displays the... (3 Replies)
I’m trying to modify someone perl script to fix a bug. The piece of code checks that the zone name you want to add is unique. However, when the code runs, it finds a partial match using grep, and decides it already exists, so the “create” command exits.

Hi,
I have files in a directory with filenames that match three specific patterns:
1) *'.L2_LAC'*
2) *'.L2_LAC_OC'*
3) *'.L2_LAC_SST'*
I would like to have an "ls" command that will list only files matching the first two patterns. However, if I type: ls *'.L2_LAC'* I will get files that... (2 Replies)
Hey guys,
I have a file with an ID which I'm using to grep out the original record from another file. Problem is I have special characters in the original file, and grep is returning only a partial record. How can I get around this?
Appreciate your help!

I am attempting to grep an exact string from a series of files within a directory and append that output to the filename when it is present in the file. I've been after this all day with no luck. Thanks for your help in advance :wall:. (4 Replies)

In the awk below I am trying to cp and paste each matching line in f2 to $3 in f1 if $2 of f1 is in the line in f2 somewhere. There will always be a match (usually more then 1) and my actual data is much larger (several hundreds of lines) in both f1 and f2. When the line in f2 is pasted to $3 in... (4 Replies)

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 invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, 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 the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
