Chapter1:Command Line Editing1
1Command Line Editing
This chapter describes the basic features of the gnu command line editing interface. 1.1Introduction to Line Editing
The following paragraphs describe the notation ud to reprent keystrokes.
The text C-k is read as‘Control-K’and describes the character produced when the k key is presd while the Control key is depresd.
The text M-k is read as‘Meta-K’and describes the character produced when the Meta key(if you have one)is depresd,and the k key is presd.The Meta key is labeled ALT on many keyboards.On keyboards with two keys labeled ALT (usually to either side of the space bar),the ALT on the left side is generally t to work as a Meta key.The ALT key on the right may also be configured to work as a Meta key or may be configured as some other modifier,such as a Compo key for typing accented characters.
If you do not have a Meta or ALT key,or another key working as a Meta key,the identical keystroke ca
n be generated by typing ESC first,and then typing k .Either process is known as metafying the k key.个人原因辞职信20字
The text M-C-k is read as‘Meta-Control-k’and describes the character produced by metafying C-k.
In addition,veral keys have their own names.Specifically, DEL , ESC , LFD , SPC , RET ,and TAB all stand for themlves when en in this text,or in an initfile(e Section1.3[Readline Init File],page4).If your keyboard lacks a LFD key,typing C-j will produce the desired character.The RET key may be labeled Return or Enter on some keyboards.
1.2Readline Interaction
Often during an interactive ssion you type in a long line of text,only to notice that the first word on the line is misspelled.The Readline library gives you a t of commands for manipulating the text as you type it in,allowing you to justfix your typo,and not forcing you to retype the majority of the line.Using the editing commands,you move the cursor to the place that needs correction,and delete or inrt the text of the corrections.Then, when you are satisfied with the line,you simply press RET .You do not have to be at the end of the line to press RET ;the entire line is accepted regardless of the location of the cursor within the line.
1.2.1Readline Bare Esntials
In order to enter characters into the line,simply type them.The typed character appears where the cursor was,and then the cursor moves one space to the right.If you mistype a character,you can u your era character to back up and delete the mistyped character.
Sometimes you may mistype a character,and not notice the error until you have typed veral other characters.In that ca,you can type C-b to move the cursor to the left,and then correct your mistake.Afterwards,you can move the cursor to the right with C-f.
