GNU Finger

2.3 User-defined Targets

Various special targets can be added as executable files in the directory `fingerdir/targets'. Each file name in this directory starts with a letter describing when to execute it, followed by a hyphen and the target name. The three letters are:

`l'

In response to a "long" finger; usually by typing `finger -l'.

`s'

In response to a "short" finger; usually the default if no options are given.

`x'

In response to either a "long" or "short" request.

For instance, the special-target file `x-.help' is run for either `finger .help' or `finger -l .help', whereas the special- target file `l-prices' is run only for `finger -l prices'.

The special-target file is run as super-user, and is given no input. By convention, all GNU Finger sites should support at least:

`.help'

Display message describing what features and special targets exist on this site.

`.site'

Display message describing the site. This may include such things as the company name, its address, and how to contact the system manager.
