Hi,
I am just trying to search for a word in a file and delete that complete line from the file if that word is present.
Cheers,
Shazin

Hi,
It can also be like this if we take it for a single file:
#!bin/sh
# The pattern that user want to add to the files
echo "Enter the pattern of the redirect"
read value
# check if the user has provided a valid pattern
if [-z "$value"] ; then
echo "You have not entered the pattern" ; exit 1
# If a pattern is entered by the User
# Searches the pattern and deletes the pattern if present in file (file 1) <filename 1>
mkdir /path/dred1
elif [grep "$value" <filename 1> > /path/dred1 && $? == 0] ; then
rm -r /path/dred1
echo "Pattern exist in <filename 1>"
sleep 1000
mkdir /path/olist
sed '/"$value"/d' <filename 1> > /path/olist
/path/olist > <filename 1>
rm -r /path/olist
echo "Pattern deleted"
else
rm -r /path/dred1
echo "Pattern does not exist in <filename 1>"
fi
fi
Please advise

exigrep
EXIGREP(8) System Manager's Manual EXIGREP(8)
NAME
EXIGREP - Search Exim's main log
SYNOPSIS
exigrep [-l] pattern [log file] ...
DESCRIPTION
The exigrep utility is a Perl script that searches one or more main log files for entries that match a given pattern. When it finds a
match, it extracts all the log entries for the relevant message, not just those that match the pattern. Thus, exigrep can extract complete
log entries for a given message, or all mail for a given user, or for a given host, for example.
The -l flag means 'literal', that is, treat all characters in the pattern as standing for themselves. Otherwise the pattern must be a Perl
regular expression. The pattern match is case-insensitive. If no file names are given on the command line, the standard input is read.
If the location of a zcat command is known from the definition of ZCAT_COMMAND in Local/Makefile, exigrep automatically passes any file
whose name ends in COMPRESS_SUFFIX through zcat as it searches it.
BUGS
This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches
would be greatly appreciated.
