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 supersede $“…”.
