Every command in arch
is accessed via the program tla
, using an
ordinary sub-command syntax:
% tla <sub-command> <options> <parameters>
A list of sub-commands can be obtained from:
% tla help
A brief summary of the options to any command is given by:
% tla <sub-command> -h
A more detailed help message for each command is given by:
% tla <sub-command> -H
For example, try:
% tla my-id -H
print or change your id
usage: tla my-id [options] [id]
-h, --help Display a help message and exit.
-H Display a verbose help message and exit.
-V, --version Display a release identifier string
and exit.
-e, --errname specify program name for errors
-u, --uid print only the UID portion of the ID
With no argument print your arch id.
With an argument, record ID-STRING as your id
in ~/.arch-params/=id
Your id is recorded in various archives and log messages
as you use arch. It must consist entirely of printable
characters and fit on one line. By convention, it should
have the form of an email address, as in this example:
Jane Hacker <jane.hacker@gnu.org>
The portion of an id string between < and > is called your
uid. arch sometimes uses your uid as a fragment when generating
unique file names.
The option -u (--uid) causes only the uid part of your id string
to be printed.
There is a great deal of regularity among commands regarding option names and parameter syntax. Hopefully, you'll pick this up as you learn the various commands.
