## 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

## 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>
