Exploring the grep options

Hi Folks,
I have one query I have a log file to which I reach to putty and I open that particular log file in vi editor and search through /pattern, Suppose I have to search

HTML Code:

<ProgramId>627857272120951075</ProgramId>

Then I have to open abc.log

Code:

cd /var/log/
ls -ltr
vi abc.log
/627857272120951075

I want to know is there any other way in which without opening the log file first
we can know that particular log file conatain the
627857272120951075 this or not any other thing grep or egrep .

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.
