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.
