Thanks for the help guys. This question does not have anything to do with the post but i am just curious. i read up about sed command for delete and for it to delete, you need to specify one input.

for example :

Code:

 sed '/$Title/d' fruit > fruittemp

but the problem with this is that it deletes entire rows which contain this information.

so i tried putting in another command which will narrow down which row needs to be deleted.

Code:

grep $Title fruit | grep $Author | sed '/$Title/d' fruit > fruittemp

but this also deletes any row which contains Persia as the title. How do i go about narrow down its seach to a specific row using two input and then deleting it?

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.
