If you have a text file that looks like this:

start_folder='/folder1/abc.txt' iterations='123' passphrase='xyz' last_command='invoke' return_value='0'

How can you pick out just xyz when looking for "passphrase"?

I know grep will get me the line but what should I use if I want just a part of the line?
Can it be done in one command or do I have to pipe several together?

If you the text has a character that would be a good delimiter, you can pipe grep to cut... ie:

cat myfile.txt|grep "iterations"|cut -d '=' -f 2 Output: '123'

the -f # is which column you want.

There may be other ways to do it, but that's the first way I can think of.

You can specify a file with grep, no need to pipe in from cat.

This is true! I always seem to get it backwards when I do that, so i just cat $thefile | grep | blah ... Cuts down on frustration, ha ha.

I should have noted that grep likely wouldn't like complicated RE patterns. Sed, however, supports the full gamut and is installed by default on pretty much every linux variant; not sure if pcregrep is.

It seems everyone likes the link I posted for the RE builder so I'll paste two others that I use:

Ah ha, okay. Yeah, just copy/paste into crontab, should be all set.

You'll want to run manually first and see if the emails come through. I tested on a FreePBX system and it went straight through to my Office 365 no problem.

If you are on FreePBX, you will need mailx installed. All dependencies are met by a default install. It's a tiny binary package.

yum -y install mailx

That is what provides the mail command.
