ZSHROADMAP(1) General Commands Manual ZSHROADMAP(1)
NAME
zshroadmap - informal introduction to the zsh manual The Zsh Manual,
like the shell itself, is large and often complicated. This section of
the manual provides some pointers to areas of the shell that are likely
to be of particular interest to new users, and indicates where in the
rest of the manual the documentation is to be found.
WHEN THE SHELL STARTS
When it starts, the shell reads commands from various files. These can
be created or edited to customize the shell. See the section
Startup/Shutdown Files in zsh(1).
If no personal initialization files exist for the current user, a func‐
tion is run to help you change some of the most common settings. It
won't appear if your administrator has disabled the zsh/newuser module.
The function is designed to be self-explanatory. You can run it by
hand with `autoload -Uz zsh-newuser-install; zsh-newuser-install -f'.
See also the section `User Configuration Functions' in zshcontrib(1).
INTERACTIVE USE
Interaction with the shell uses the builtin Zsh Line Editor, ZLE. This
is described in detail in zshzle(1).
The first decision a user must make is whether to use the Emacs or Vi
editing mode as the keys for editing are substantially different.
Emacs editing mode is probably more natural for beginners and can be
selected explicitly with the command bindkey -e.
A history mechanism for retrieving previously typed lines (most simply
with the Up or Down arrow keys) is available; note that, unlike other
shells, zsh will not save these lines when the shell exits unless you
set appropriate variables, and the number of history lines retained by
default is quite small (30 lines). See the description of the shell
variables (referred to in the documentation as parameters) HISTFILE,
HISTSIZE and SAVEHIST in zshparam(1). Note that it's currently only
possible to read and write files saving history when the shell is in‐
teractive, i.e. it does not work from scripts.
The shell now supports the UTF-8 character set (and also others if sup‐
ported by the operating system). This is (mostly) handled transpar‐
ently by the shell, but the degree of support in terminal emulators is
variable. There is some discussion of this in the shell FAQ,
https://www.zsh.org/FAQ/. Note in particular that for combining char‐
acters to be handled the option COMBINING_CHARS needs to be set. Be‐
cause the shell is now more sensitive to the definition of the charac‐
ter set, note that if you are upgrading from an older version of the
shell you should ensure that the appropriate variable, either LANG (to
affect all aspects of the shell's operation) or LC_CTYPE (to affect
only the handling of character sets) is set to an appropriate value.
This is true even if you are using a single-byte character set includ‐
ing extensions of ASCII such as ISO-8859-1 or ISO-8859-15. See the de‐
scription of LC_CTYPE in zshparam(1).
Completion
Completion is a feature present in many shells. It allows the user to
type only a part (usually the prefix) of a word and have the shell fill
in the rest. The completion system in zsh is programmable. For exam‐
ple, the shell can be set to complete email addresses in arguments to
the mail command from your ~/.abook/addressbook; usernames, hostnames,
and even remote paths in arguments to scp, and so on. Anything that
can be written in or glued together with zsh can be the source of what
the line editor offers as possible completions.
Zsh has two completion systems, an old, so called compctl completion
(named after the builtin command that serves as its complete and only
user interface), and a new one, referred to as compsys, organized as
library of builtin and user-defined functions. The two systems differ
in their interface for specifying the completion behavior. The new
system is more customizable and is supplied with completions for many
commonly used commands; it is therefore to be preferred.
The completion system must be enabled explicitly when the shell starts.
For more information see zshcompsys(1).
Extending the line editor
Apart from completion, the line editor is highly extensible by means of
shell functions. Some useful functions are provided with the shell;
they provide facilities such as:
insert-composed-char
composing characters not found on the keyboard
match-words-by-style
configuring what the line editor considers a word when moving or
deleting by word
history-beginning-search-backward-end, etc.
alternative ways of searching the shell history
replace-string, replace-pattern
functions for replacing strings or patterns globally in the com‐
mand line
edit-command-line
edit the command line with an external editor.
See the section `ZLE Functions' in zshcontrib(1) for descriptions of
these.
OPTIONS
The shell has a large number of options for changing its behaviour.
These cover all aspects of the shell; browsing the full documentation
is the only good way to become acquainted with the many possibilities.
See zshoptions(1).
PATTERN MATCHING
The shell has a rich set of patterns which are available for file
matching (described in the documentation as `filename generation' and
also known for historical reasons as `globbing') and for use when pro‐
gramming. These are described in the section `Filename Generation' in
zshexpn(1).
Of particular interest are the following patterns that are not commonly
supported by other systems of pattern matching:
** for matching over multiple directories
| for matching either of two alternatives
~, ^ the ability to exclude patterns from matching when the EX‐
TENDED_GLOB option is set
(...) glob qualifiers, included in parentheses at the end of the pat‐
tern, which select files by type (such as directories) or at‐
tribute (such as size).
GENERAL COMMENTS ON SYNTAX
Although the syntax of zsh is in ways similar to the Korn shell, and
therefore more remotely to the original UNIX shell, the Bourne shell,
its default behaviour does not entirely correspond to those shells.
General shell syntax is introduced in the section `Shell Grammar' in
zshmisc(1).
One commonly encountered difference is that variables substituted onto
the command line are not split into words. See the description of the
shell option SH_WORD_SPLIT in the section `Parameter Expansion' in zsh‐
expn(1). In zsh, you can either explicitly request the splitting (e.g.
${=foo}) or use an array when you want a variable to expand to more
than one word. See the section `Array Parameters' in zshparam(1).
PROGRAMMING
The most convenient way of adding enhancements to the shell is typi‐
cally by writing a shell function and arranging for it to be au‐
toloaded. Functions are described in the section `Functions' in zsh‐
misc(1). Users changing from the C shell and its relatives should no‐
tice that aliases are less used in zsh as they don't perform argument
substitution, only simple text replacement.
A few general functions, other than those for the line editor described
above, are provided with the shell and are described in zshcontrib(1).
Features include:
promptinit
a prompt theme system for changing prompts easily, see the sec‐
tion `Prompt Themes'
zsh-mime-setup
a MIME-handling system which dispatches commands according to
the suffix of a file as done by graphical file managers
zcalc a calculator
zargs a version of xargs that makes the find command redundant
zmv a command for renaming files by means of shell patterns.
