This string is devided into one space between substrings. This substrings are,

aabab|bcbcbcbbc|defgh|paswd123
dedededede|efef|ghijklmn|paswd234
ghghghghgh|ijijii|klllkkk|paswd345
lmlmlmmm|nononononn|opopopopp|paswd456

Now i want to get paswd234 by searching corresponding ghijklmn
similarly want to get paswd345 by searching corresponding klllkkk
Do you want password for ghijklmn and klllkkk alone or do you want all the passwords ?

For all passwords

Code:
tr ' ' '\n' < input.txt | sed -n -e "s/.*|\(.*\)/\1/p"

SYSTEMD-ASK-PASSWORD-CONSOLE.SERVICE(8) 	       systemd-ask-password-console.service		   SYSTEMD-ASK-PASSWORD-CONSOLE.SERVICE(8)

NAME

       systemd-ask-password-console.service, systemd-ask-password-console.path, systemd-ask-password-wall.service, systemd-ask-password-wall.path
       - Query the user for system passwords on the console and via wall

SYNOPSIS

       systemd-ask-password-console.path

       systemd-ask-password-wall.service

       systemd-ask-password-wall.path

DESCRIPTION

       systemd-ask-password-console.service is a system service that queries the user for system passwords (such as hard disk encryption keys and
       SSL certificate passphrases) on the console. It is intended to be used during boot to ensure proper handling of passwords necessary for
       boot.  systemd-ask-password-wall.service is a system service that informs all logged in users for system passwords via wall(1). It is
       intended to be used after boot to ensure that users are properly notified.

       See the developer documentation[1] for more information about the system password logic.

       Note that these services invoke systemd-tty-ask-password-agent(1) with either the --watch --console or --watch --wall command line
       parameters.
