k

[count]rc Replace the current character with c.
[count]x Delete current character.
[count]X Delete preceding character.
[count]. Repeat the previous text modification command.
[count]˜ Invert the case of the current character and advance the cursor.
[count]_ Causes the count word of the previous command to be appended at the current cur-
sor location and places the editor in input mode at the end of the appended text.
The last word is used if count is omitted.
* Appends an * to the current word and attempts file name generation. If no match
is found, the bell rings. If a match is found, the word is replaced by the matching
string and the command places the editor in input mode.
ESC
\ Attempt file name completion on the current word. Replaces the current word
with the longest common prefix of all filenames matching the current word with an
asterisk appended. If the match is unique, a / is appended if the file is a directory
and a space is appended if the file is not a directory.
Other Edit Commands
[count]ymotion
y
[count]motion Yank current character through character that motion would move the cursor to
and puts them into the delete buffer. The text and cursor are unchanged.
Y Yanks from current position to end of line. Equivalent to y$.
u Undo the last text modifying command.
U Undo all the text modifying commands performed on the line.
[count]v Returns the command fc -e ${VISUAL:-${EDITOR:-vi}}
count in the
input buffer. If count is omitted, the current line is used.
^L Line feed and print current line. Has effect only in control mode.
^J (New line) Execute the current line, regardless of mode.
^M (Return) Execute the current line, regardless of mode.
# Equivalent to I# followed by Return. Sends the line after inserting a # in front
of the line and after each new-line. Useful for inserting the current command line
in the history list without executing it.
= List the filenames that match the current word if an asterisk were appended to it.
@letter The user’s alias list is searched for an alias by the name
_letter and if an alias of
this name is defined, its value is inserted on the input queue for processing.
EXTERNAL INFLUENCES
Environment Variables
LC_COLLATE determines the collating sequence used in evaluating pattern matching notation for file name
generation.
LC_CTYPE determines the classification of characters as letters, and the characters matched by character
class expressions in pattern matching notation.
If LC_COLLATE or LC_CTYPE is not specified in the environment or is set to the empty string, the value of
LANG is used as a default for each unspecified or empty variable. If LANG is not specified or is set to the
empty string, a default of "C" (see lang(5)) is used instead of LANG. If any internationalization variable con-
tains an invalid setting, ksh behaves as if all internationalization variables are set to "C". See environ(5).
International Code Set Support
Single-byte character code sets are supported.
RETURN VALUE
Errors detected by the shell, such as syntax errors, cause the shell to return a non-zero exit status. Other-
wise, the shell returns the exit status of the last command executed (also see the
exit command above).
If the shell is being used non-interactively, execution of the shell file is abandoned. Runtime errors
detected by the shell are reported by printing the command or function name and the error condition. If
the line number on which the error occurred is greater than one, the line number is also printed in brackets
([]) after the command or function name.
WARNINGS
File descriptors 10 and 54 through 60 are used internally by the Korn Shell. Applications using these and
forking a subshell should not depend upon them surviving in the subshell or its descendants.
