Whenever you find yourself writing the same 4 lines 9 times running, there's probably a better way. I'd suggest a case statement:
You can redirect in $FILENAME at the bottom that way, instead of repeating it over and over. Without a filename, grep just reads from standard input, which is what's being redirected at the bottom of the case statement there.
Ok so i had to create a file and put some random text into it which i did.
THen u make a script which takes 2 arguments.
The first being a line of text, the second being your newly created file.

zegrep
ZGREP(1) BSD General Commands Manual ZGREP(1)NAME
zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files
SYNOPSIS
zgrep [grep-flags] [--] pattern [files ...]
zegrep [grep-flags] [--] pattern [file ...]
zfgrep [grep-flags] [--] pattern [file ...]
DESCRIPTION
zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).
The grep-flags and pattern arguments are passed on to grep(1). If an -e flag is found in the grep-flags, zgrep will not look for a pattern
argument.
zegrep calls egrep(1), while zfgrep calls fgrep(1).
EXIT STATUS
In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.
