I've removed advertising from most of this site and will eventually clean up the few pages where it remains.

While not terribly expensive to maintain, this does cost me something. If I don't get enough donations to cover that expense, I will be shutting the site down in early 2020.

If you found something useful today, please consider a small donation.

Having used Unix since before "cut" was apt to be on the machine, I'm used to using "sed" to extract what I want from a line, but "cut" is much easier:

 apl$ cut -d : -f 5 /etc/passwd
Unprivileged User
System Administrator
System Services
Unknown User
Sendmail User
World Wide Web Server
MySQL Server
sshd Privilege separation

Now that's not fun with sed.

Cut can also use character positions:

cut -c 1-8  /etc/passwd

You can also use the substr function of expr to extract string data.
