Top Forums Shell Programming and Scripting Retrieving line number from grep Post 302759985 by One_2_three on Wednesday 23rd of January 2013 07:29:21 AM

thank you very much. i have 1 more question.

i am actually trying to update the file with matching pattern. the pattern will be unique so there will always be 1 pattern.

Code:
$ sed $var`s`/$oldpattern/$newpattern file.txt

i tried using the () but i still get errors. is it because the code after my sed is not a command due to the `s`?

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.
