Synopsis:
input "<prompt>" <command> [<arguments>]
input_char "<prompt>" <command> [<arguments>]
Description:
This command is primarily for use inside scripts. It allows the client
to present the user with a visible prompt for specific commands. This
can be used for interactive commands, for command confirmation, etc.
Multiple commands may be specified if surrounded with curly braces.
The variant INPUT_CHAR words the same as INPUT, except it only takes a
single character. The primary difference is that it does not require
that a carriage return be entered before executing the command; the first
keystroke will trigger it.
Options:
-noecho stops the echoing of characters as they are typed
Examples:
To let a command ask for confirmation:
input "Are you REALLY sure you want to do this? (y/n) " {
if ( [$0] == [y] ) exec rm -rf *
}
The basis for a simple paging mechanism:
input_char "Press 'q' to quit, any other key to continue: " {
unless ( [$0] == [q] ) {
/* do whatever */
}
}
Aliases:
These commands are functionally equivalent to the $"..." expando. In
truth, they supersedes $"...".
