Search in $GLDATA/parms/cur_fiscalyear.lis for the line containing "CONSOL" and return the second column of that line. Which, according to that data, should be returning '2011'. Oh, and forgot the first part, cur_fy is the variable holding that information '2011'. Its declaring cur_fy as a variable which expands to whatever grep's looking for which in this case is what's next to "CONSOL" in cur_fiscalyear.lis

If you have command line access try this: Type
Code:
 df

and hit enter. Should give some results similar to this :
Code:
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/disk0s1           1048576    730240    307856  71% /
devfs                       34        34         0 100% /dev
/dev/disk0s2s1        14677320  13831888    845432  95% /private/var

Good so far? Let's pipe 'df' through 'grep' and look for the word "Filesystem" in the results and only return the line containing that.
Code:
 df | grep Filesystem

should return something like this
Code:
 Filesystem           1K-blocks      Used Available Use% Mounted on

. Good so far? Ok last step, let's pipe all of that through 'awk' so we can see what's in the second column of those results "1K-blocks".
Code:
 df | grep Filesystem | awk '{print $2}'

and we get our result. Hope that helped some.

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.
