grep for a particular field
Hi All,

I have the following in a text file

Code:
#---- Set Silent License Acceptance
#---- Accept license agreement: remove # sign
#----                 example: LICENSE_ACCEPTED=true
#---- if the LICENSE_ACCEPTED is anything other then true the installation will exit
#----        no log will be produced, no indication of failure provided
#----
#---- By removing the # sign before #LICENSE_ACCEPTED=false and changing false to true
#---- you have signified acceptance of the Netcool/Impact 5.1.1 license agreement
#LICENSE_ACCEPTED=false

I want to grep only the LICENSE_ACCEPTED=false alone. The LICENSE_ACCEPTED=false is present at the bottom I don't want to grep anything in the middle and this LICENSE_ACCEPTED=false has a '#' symbol also. So, how to grep this part alone

I am actually grepping this field and making false to true by using the following command but the current command greps all the LICENSE_ACCEPTED

Code:
echo "`grep -q LICENSE_ACCEPTED $NCHOME/installSilent_response.txt && sed 's#LICENSE_ACCEPTED=[^ ]*#LICENSE_ACCEPTED='${RESPONSE}#g'' $NCHOME/installSilent_response.txt || sed '$ a LICENSE_ACCEPTED='${RESPONSE}' $NCHOME/installSilent_response.txt'`" >> $NCHOME/installSilent_response_hp.txt

So,

1. how to remove the # from the legal unique LICENSE_ACCEPTED
2. And then just grep the unique LICENSE_ACCEPTED

Thanks for any help
Dinesh

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.
