Search file pattern using grep command
I 'm writing a script to search particular strings from log files. The log file contains lines start with *. The file may contain many other lines start with *. I need to search a particular line from my log file. The grep command is working in command line , but when i run my script, Its printing all files in that directory . ( Example : script1.shScript2.shMessage CompletedScript4.sh)

Any suggestions?


Ex:

**********************Message Completed**********
Code:
tail -F file.log  | while read LINE
do
   echo $LINE | awk '{print $0}' | grep "[\*]*.Message Completed*" >>$TestFile
done



Thanks for your help !

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.
