Using Grep to Define a Variable

I am using korn shell unix.

I have a script that I am working with to do a check for me using a text file.

#finds "Time" from the text file and cuts the second field from the #line

A= grep Time test.txt | cut -f2

# the "#Missing" is being pulled from the second field of the text #file

if [ "$A" = #Missing ]
then
echo "page me"
fi

My problem is that I am unable to get the 'echo "page me"' to echo back onto the screen. This tells me that the check isn't successful- or at least that is what I think it is telling me.

My if statement may be incorrect- I've tried '-eq', but no luck there either.

I'm also not certain if I can use grep to try and define a variable. I've even attempted to use awk. Everything works on the command line, by itself (like running the grep command).

Anyone have any ideas? I'm pretty new at Unix.

Thanks,

Chris

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.
