Using csh & tcsh

What the Settings Mean

There are many special keys on your terminal; the most important are those that per form the erase, kill, werase, rprnt, lnext, stop, start, intr, susp, and eof functions.

Line Editing Settings

The erase, kill, werase, rprnt, and lnext characters let you do simple editing of the current command line. (Some systems do not support werase or rprnt.) If you use tcsh, you also have access to a built-in general purpose editor, described in Chapter 7, The tcsh Command-Line Editor.

erase

To backspace over the last character, type the erase character. Common erase characters are CTRL-H (also known as BACKSPACE) or DEL. Terminals vary in what they provide.

(If you're using tcsh, CTRL-W might not do word erase. Try ESC DEL or ESC CTRL-H instead.)

rprnt

The rprnt (reprint) character redisplays the command line you're typing—useful if output ...
