## INSTALLATION NOTES
Besides oh-my-zsh, `scd` can be used with *bash*, *dash* or *tcsh*
shells and is also available as [Vim](https://www.vim.org/) plugin and
[IPython](https://ipython.org/) extension. For installation details, see
shells and is also available as Vim plugin
[scd.vim](https://github.com/pavoljuhas/scd.vim) and
[IPython](https://ipython.org) extension. For installation details, see
https://github.com/pavoljuhas/smart-change-directory.

scd [options] [pattern1 pattern2 ...]
```
## PATTERNS
Patterns may use all zsh [glob operators](
http://zsh.sourceforge.net/Doc/Release/Expansion.html#Glob-Operators)
available with *extendedglob* option. Specified patterns must match
the absolute path and at least one of them must match in the tail.
Several special patterns are also recognized as follows:
<dl><dt>
^PAT</dt><dd>
PAT must match at the beginning of the path, for example, "^/home"</dd><dt>
PAT$</dt><dd>
require PAT to match the end of the path, "man$"</dd><dt>
./</dt><dd>
match only subdirectories of the current directory</dd><dt>
:PAT</dt><dd>
require PAT to match over the tail component, ":doc", ":re/doc"</dd>
</dl>

usage: scd [options] [pattern1 pattern2 ...]
Go to a directory path that contains all fixed string patterns. Prefer
recent or frequently visited directories as found in the directory index.
Go to a directory path that matches all patterns. Prefer recent or
frequently visited directories as found in the directory index.
Display a selection menu in case of multiple matches.
Special patterns:
^PAT match at the path root, "^/home"
PAT$ match paths ending with PAT, "man$"
./ match paths under the current directory
:PAT require PAT to span the tail, ":doc", ":re/doc"
Options:
-a, --add add specified directories to the directory index.
-a, --add add current or specified directories to the index.
--unindex remove current or specified directories from the index.
-r, --recursive apply options --add or --unindex recursively.
--alias=ALIAS create alias for the current or specified directory and
store it in ~/.scdalias.zsh.
--unalias remove ALIAS definition for the current or specified
directory from ~/.scdalias.zsh.
-A, --all include all matching directories. Disregard matching by
directory alias and filtering of less likely paths.
Use "OLD" to purge aliases to non-existent directories.
-A, --all display all directories even those excluded by patterns
in ~/.scdignore. Disregard unique match for a directory
alias and filtering of less likely paths.
-p, --push use "pushd" to change to the target directory.
--list show matching directories and exit.
-v, --verbose display directory rank in the selection menu.
-h, --help display this message and exit.
