Hi,

30 Useful Linux Commands for System Administrators (NEW admin's);

Quote:

In this article we are going to review some of the useful and frequently used Linux or Unix commands for Linux System Administrators that are used in their daily life. This is not a complete but it’s a compact list of commands to refer when needed. Let us start one by one how we can use those commands with examples.

I will add that this article seems to target new admin.

nice short little list. not sure i would call them administrative commands, but they are a good set of basic linux commands. thanks for reminding me about the last command. i had forgotten about it until i read the link.

I agree with you.

w = easy for old gits like me to remember.
whoami = useful for the morning after the night before.
more = used it less than less, more or less.
cat = why no dog?

sad, is the lack of any "man" references.
But if you're an 'admin', you should know how to get help in *nix.

I always get a chuckle when I need to look up the format codes for date with man date

As Oldham seems to be out of cats, perhaps this will help.

Code:

alias dog=cat

i like the added commands. keep at it. you might also want to add htop as an option to top. very nice little tool. not standard on most systems, but should be available as an added package at least.

No, we're freshly stocked. We've been kidnapping (or catnapping?

) them from all over the UK.

Ahhh, it is good to know that Slackware pre-release preparations have been made
