Execution problems with grep command in scripting
Hi All,
I was looking for grep command option which can exactly matches the word in a file, for examples you may be seeing one word that is also in another word, there might be lkk0lv23 and a lkk0lv234 in which case lkk0lv23 will put BOTH hosts from the grep in.

I was using this in a bash script to grep multiple entries in a file and this causing me a duplicate copies in final output file, how to eliminate it, is their a similar command that I can use.





Code:
 grep -i "$line" "$CFILE"; sleep 1 >> "$OFILE"

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.
