These days, even a wireless router probably has awk. If you're running anything with Linux or UNIX in its name you should have it.
grep prints '<stdin>' because you didn't give it a file name, it was reading from
tr instead, through a pipe, also called 'standard input'. So that's not quite what you want.
grep usually has limits on how long a line it will process, and tr -d '\n' turns it into one giant line, so that's not a good solution anyway.
There are ways with grep, involving calling grep multiple times, and possibly sorting and merging its output. I think the awk way is the closest to what you asked for.

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.
