# Readline
|
||||
|
||||
GNU Readline is a library commonly used to make prompts for user input. It has
|
||||
a lot of useful keybinding for line editing and also provides an history of the
|
||||
line read. You can usually use these bindings with the shell prompt too.
|
||||
|
||||
There are two operating modes: Emacs style or VI style. Usually, Emacs is the
|
||||
default mode.
|
||||
|
||||
Take a look, try them and make a cheatsheet of the most useful ones.
|
||||

||||

# Readline
|
||||
|
||||
GNU Readline és una biblioteca comunament utilitzada per a llegir línies de text
|
||||
teclejades. Té moltes dreceres per a l'edició de la línia d'entrada i proveeix
|
||||
també un historial de les línies entrades. Podeu generalment fer servir aquestes
|
||||
dreceres amb l'intèrpret d'ordres.
|
||||
|
||||
Té dos modes operatius, l'u amb un estil de dreceres d'Emacs i l'altre de VI.
|
||||
|
||||
Mireu una mica que fa cadascuna de les dreceres, proveu-les i prengueu notes
|
||||
dels més útils.
