ZSH FEATURES
|
|
------------
|
|
|
|
very close to ksh/sh grammar, with csh additions
|
|
most features of ksh, bash, and tcsh
|
|
can emulate ksh or POSIX sh
|
|
81 builtins, 102 options, 162 key bindings
|
|
short for loops, ex: for i (*.c) echo $i
|
|
select
|
|
shell functions
|
|
conditional expressions (test builtin, [ ... ], and ksh-style [[ ... ]])
|
|
global aliases (may be expanded anywhere on the line)
|
|
directory stack access with =num
|
|
process substitution (vi =(cmd) edits the output of cmd)
|
|
generalized pipes (ls foo >>(cmd1) 2>>(cmd2) pipes stdout to cmd1
|
|
and stderr to cmd2)
|
|
arithmetic expressions
|
|
advanced globbing:
|
|
ls **/file searches recursively for "file" in subdirectories
|
|
ls file<20-> matches file20, file30, file100, etc.
|
|
ls *.(c|pro) matches *.c and *.pro
|
|
ls *(R) matches only world-readable files
|
|
ls *.c~lex.c matches all .c files except lex.c
|
|
null command shorthands:
|
|
"< file" is same as "more <file"
|
|
"> file" is same as "cat >file"
|
|
">> file" is same as "cat >>file"
|
|
ksh-style coprocesses
|
|
automatic file stream teeing (ls >foo >bar puts output in two places)
|
|
chpwd() function run every time you change directory (useful for
|
|
updating the status line)
|
|
job control
|
|
csh-style history
|
|
full vi line editing, including "c2w" and "y$" and such things
|
|
full emacs line editing
|
|
incremental history search
|
|
magic-space history
|
|
spelling correction
|
|
array parameters
|
|
$MACHTYPE, $VENDOR and $OSTYPE identify the host machine
|
|
$LINENO, $RANDOM, $SECONDS, $cdpath, $COLUMNS, $fignore, $HISTCHARS, $mailpath
|
|
$UID, $EUID, $GID, $EGID and $USERNAME can be assigned to
|
|
with autocd option, typing a directory name by itself is the same as
|
|
typing "cd dirname"
|
|
menu completion: pressing TAB repeatedly cycles through the possible matches
|
|
incremental path hashing
|
|
automatic process time reporting for commands that run over a certain limit
|
|
full tcsh-style prompt substitution
|
|
utmp login/logout reporting
|
|
with histverify option, performing csh-style history expansions causes the
|
|
input line to be brought up for editing instead of being executed
|
|
with sunkeyboardhack option, accidentally typed trailing ` characters
|
|
are removed from the input line (for those of you with Sun keyboards :-) )
|
|
autoloaded functions (loaded from a file when they are first referenced)
|
|
"cd old new" replaces "old" with "new" in directory string
|
|
generalized argument completion, including:
|
|
- command name completion
|
|
- filename and path completion
|
|
- hostname completion
|
|
- key binding completion
|
|
- option completion
|
|
- variable name completion
|
|
- user-specified keyword completion
|
|
- anything else you can think of
|
|
prompt on right side of screen
|
|
directory stacks
|
|
history datestamps and execution time records
|
|
command scheduling (like at(1), but in the shell's context)
|
|
tty mode freezing
|
|
up to 9 startup files (but you only need 1 or 2)
|
|
really 8-bit clean, and we mean it this time
|
|
which -a cmd lists all occurrences of "cmd" in the path
|
|
dynamically loadable binary modules
|
