Useful Commands

Introductory AFS commands

Most of the AFS commands you'll ever want to know or use can be found in the Unix Command Summary. This document contains all the basics, plus intermediate and advanced commands that everyone uses as short cuts.

Intermediate AFS commands

You can customize many of the basic commands you already know by combining them with "flags" or "options." (For example, to list the contents of a directory you'd type "ls", but to see at a glance which items were files and which sub-directories, you'd type "ls -F": this marks sub-directories with a slash so it's more obvious.) Most of the useful options are included in the Unix Command Summary, but you can also hunt for new ones online.

Learn more about commands online
You can often get more information about an AFS command by adding a "help argument" or "flag" to the command while at the command prompt. For example, say you wanted more information about the "fs" command.

To get a list of fs subcommands, you'd type:

fs help
To get a somewhat cryptic syntax list for a subcommand, you'd type:
fs [subcommand] -help
To get a look at the rather worthless online manual concerning "fs", you'd type:
man fs
Press the space bar to page down through the text. Press "q" to get out of the manual pages. You might notice that the information seems rather poorly presented. This is usually the case with manual pages, but the "man" command can sometimes unearth extremely useful stuff or help you figure things out.

A few useful command options

  • ls -a     This lists all the invisible "dot" files in a directory. It's very useful when setting permissions in web directories that require the use of .htaccess files.
  • ls -F     This was discussed in the intro paragraph to this intermediate commands section, but note that on most Macs and Windows computers the "Tab" key will do the very same thing. One keystroke instead of four.
  • ls -latr     This lists the contents of a directory in reverse order (most recently changed at the bottom of the list) and includes all sorts of additional information, like who created the file originally.

Advanced AFS commands

Refers you to a list of advanced commands, such as fs (file) commands, pts group commands, vos server commands and other useful information about AFS paths and file layout.
