Using "sed" to update RECURSIVELY a value within a directory in a Red Hat Machine
Hi All,
I spent the whole morning trying to create a shell script ( using "sed" command ) that looks for a value in a directory and its sub directory than changes it with another value but couldn't find the way
a first step, allowded me to trace all the files that contain it and even change this value but not into the file but on the standard output ( the screen ), here after the command :
Code:
grep -R 10.220.22.240 * | grep 8080 | sed 's/10\.220\.22\.240/localhost/g'
RESULT ON SCREEN ( here after a single line for exemple ):
Now, what i'am attempting to do, is to change the value "10.220.22.240" with "localhost" INTO ALL THESE FILES !!!
i made this script below but i shoul be missing something :
Code:
===========================
#!/bin/ksh
grep -R 10.220.22.240 * | grep 8080 > ListaFile
for a in ListaFile
do
sed 's/10\.220\.22\.240/localhost/g' < a > b
==========
one of the line included in "ListaFile", gives :
==============
testo/nav-up.htm_al13gen09:<td width="82" bgcolor="#6699CC"><div align="center"><a href="http://10.220.22.240:8080/dashboard.action" target="content" class="menu" on Click="MM_showHideLayers('comm','','hide','description','','hide','board','','hide','application','','hide','papers','','hide','news','','hide','wiki','','show')" > wiki</a></div></td>
==============
Can you help please ? thanx

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.
