Top Forums Shell Programming and Scripting Grepping file and returning passed variable if the value does not exist in file at all. Post 302517321 by personalt on Tuesday 26th of April 2011 12:17:33 PM

Thank you very much...

I actually have a few hundred fields to check. Since I am scripting the scripts I ended up converting this to following. I also made change to only search for instances when my field is wrapped in single quotes. And then to re-grep to only print instances where the field was not found at least once.

I would assume it would be more efficient to open the file once but I only need to run this script once a day prior to file check in and for my source file it runs in 15 seconds. The infile format is a pseudo xml file.
Code:
awk '/'\''OPEN'\''/ {o++} END {print "OPEN:" o }' infile | grep -v '[0-9]'
awk '/'\''CLOSE'\''/ {o++} END {print "CLOSE:" o }' infile | grep -v '[0-9]'
awk '/'\''HIGH'\''/ {o++} END {print "HIGH:" o }' infile | grep -v '[0-9]'

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.
