Top Forums UNIX for Dummies Questions & Answers Need help to escape special characters in Korn shell script Post 302316130 by Thinkpositiv on Thursday 14th of May 2009 07:23:17 AM

Hi,

I'm back with a similar issue Smilie
Basically I'm grep'ing a file for a pattern. The pattern contains " (double quotes) and a space. So I escaped the quotes. But how do I use this variable in the grep call?
Code:
typeset searchString="path=\"asdf\" mode=\"jkl\""
typeset found=`grep "$searchString" $cs_rte_configtransform` #(a)
typeset found=`grep '$searchString' $cs_rte_configtransform` #(b)

Neither (a) nor (b) works. From my understanding I'd have to use (a), but searchString should contain path=\"asdf\", so I need to declare it like this?
Code:
typeset searchString="path=\\\"asdf\\\" mode=\\\"jkl\\\""

Still no results, the variable found is always empty, although the searchString manually pasted into the grep call works.

Has anyone an idea/hint for me?
Thanks, regards, Thinkpositiv

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. AUTHOR
