redirecting output and creating condition for while loop.
I have 2 questions.
1) Is there a means of directing output to a file (">") while making it still output to the console?
I have a script that calls another lengthy script.
2) I can direct the output of the lengthy script and grep it for the words "good" or "bad" to know if I need the run the script again, but how would this exactly work? I'm just looking for the most efficient code.
Rather than putting anything in a file, I'd like to just grep the output:
I'm wondering how to evaluate if ". ./lengthyScript.sh | grep bad" is true of not. If you have any suggestions here, I'd really appreciate 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.
