I think you need to use -E with grep to invoke extended regular expressions. But also, if the argument passes the test, it will go to stdout. The -q option will fix that. So try this:
$ ls
monkey.txt
banana.csv
tree.txt
$ myscript monkey.txt tree.txt
All extensions ARE alike.
$ myscript *txt
All extensions ARE alike.
$ myscript monkey.txt banana.csv
All extensions are NOT alike.
$ myscript *
All extensions are NOT alike.

gzegrep
GZGREP(1) General Commands Manual GZGREP(1)NAME
gzgrep, gzegrep, gzfgrep - search possibly compressed files for a regular expression
SYNOPSIS
gzgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
gzgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci-
fied, 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 gzgrep is invoked as gzegrep or gzfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, gzgrep
uses it as the grep program to be invoked. For example:
for sh: GREP=fgrep gzgrep string files
for csh: (setenv GREP fgrep; gzgrep string files)
