Help with grepping data from a text file
Hello,
I have a text file which contains a list of strings which I want to grep from another file where these strings occur and print out only these lines.
I had earlier used the grep command
Quote:
grep -f File1 File2
where File1 was the file containing the strings to be grepped (Source File) and File2 the Target File from which the strings had to extracted.
And this had worked, but this time the above syntax does not work.
I am in a windows environment and tried both GREP for DOS as well as GREP32 but in each case I do not get the desired results.
Any help would be appreciated since the amount of strings to be grepped is quite large.

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.
