How do I echo username, full name, and login time from finger into columns? I'm using bash on openSUSE13.1

Basically I have three users logged in to my machine right now. Test User1, Test User2, and Test User3.

I would like to use finger to get username, full name and the time they logged into the machine.

I would like to output the information like so:

Login        Name            Login Time

testuser1    Test User1      1300

testuser2    Test User2      1600

testuser3    Tesr User3      1930

I have two tabs in between Login and Name and three tabs between Login Time. The same goes for the user information below each header.

I cannot figure out how to pull this data from finger very well and I absolutely cannot figure out how to get the information into nice, neat, readable columns. Thanks in advance for any help!

Solution

This might not be perfect so you'll have to play around with substr starting and ending points. Should be good enough to get you started:

finger -s testuser1 testuser2 testuser3 | awk '{print substr($0,1,31),substr($0,46,14)}'
