I am in need of some help with UNIX/Linux, particularly sed and awk:

Please help me Display from /etc/passwd a list of users and their shells for those using the
Korn shell or Bash shell. Order the output by the absolute pathname of the shell used.

Thank you.

Solution

from /etc/passwd

first we need to cut itaccording to required specifications

1)cut -d: -f1/etc/passwd

then now use sed command:

2)sed \'s/:.*//\' /etc/passwd

this is to make sure that it seperates the required format

then the last command which is to be used is:

awk -F: \'{print $1}\' /etc/passwd

this is used to print the requiired format
