Script extract text from txt file with grep

All,

I require a script that grabs some text from the gitHub API and will grep (or other function) for a string a characters that starts with (") quotes followed by two letters, may contain a pipe |, and ending with ) . What i have so far is below but it's not returning anything.

Code:

#!/bin/bash
IFS_bak=$IFS
IFS=$'\r\n'
uid='xxxxxxxxxxxxx'
GH_OAUTH='xxxxxxxxxxxxxxxxxxxxxxxxxxx'
curl https://raw.githubusercontent.com/SomeOrganization/Infrastructure/SomeRepository/SomeContainer/SSHKeyserverList.sh?access_token=$GH_OAUTH > somefile.txt
cat somefile.txt | grep '^\"[a-z][a-z]\|\\)' > outputfile.txt

Example text reply from the github API:

Code:

"SomeUser1" ) # Some Name (Some@emailDomain.com)
            NewSSHKey="ssh-rsa xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx some@email.com"
            ;;
       "SomeUser2" ) # Some Name (Some@emailDomain.com)
            NewSSHKey="ssh-rsa xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx some@email.com"
            ;;
         "SomeUser3" | "alternateUserName3 ) # Some Name (Some@emailDomain.com)
            NewSSHKey="ssh-rsa xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx some@email.com"
                ;;

In summary, what i need is this line:

"UserName" ) # Users Name (Users@e-mailDomain.com)
OR in case of multiple user names i need
"UserName" | SecondaryUserName ) # Users Name (Users@e-mailDomain.com).

In my code above i'm trying to 'grep' for the string that starts with " and eds with ) and may contain a pipe (but may not contain a pipe). I would like the script to print all of the lines containing that string to a text file, is what i have on the right path or am i way off base here?

Thanks for reading,

Choco

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.
