Advanced grep'in... grep for data next to static element.
I have a directory I need to grep which consists of numbered sub directories. The sub directory names change daily. A file resides in this main directory that shows which sub directories are FULL backups or INCREMENTAL backups.

My goal is to grep the directory for the word "full" and then preceding that word in the file is the name of the sub directory the FULL backup is in. So I then need to grab that name and execute a tar or cp command on that directory.

EXAMPLE: contents of the directory are: 123 124 125 126 file.txt file2.txt

In file.txt there is a line that reads: [backup 123 full type etc etc]
This tells me the FULL backup is in the 123 directory (the data right in front of the word FULL)

I then need to tar or cp the 123 directory.

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.
