Query or set the primary prompt string. When executing interactively, Octave displays the primary prompt when it is ready to read a command.
The default value of the primary prompt string is
"\s:\#> "
. To change it, use a command likeoctave:13> PS1 ("\\u@\\H> ")which will result in the prompt ‘boris@kremvax> ’ for the user ‘boris’ logged in on the host ‘kremvax.kgb.su’. Note that two backslashes are required to enter a backslash into a double-quoted character string. See Strings.
