# scd - smart change of directory
|
|
|
|
Define `scd` shell function for changing to any directory with
|
|
a few keystrokes.
|
|
|
|
`scd` keeps history of the visited directories, which serves as an index of
|
|
the known paths. The directory index is updated after every `cd` command in
|
|
the shell and can be also filled manually by running `scd -a`. To switch to
|
|
some directory, `scd` needs few fragments of the desired path to match with
|
|
the index. A selection menu is displayed in case of several matches, with a
|
|
preference given to recently visited paths. `scd` can create permanent
|
|
directory aliases, which appear as named directories in zsh session.
|
|
|
|
## INSTALLATION NOTES
|
|
|
|
Besides oh-my-zsh, `scd` can be used with *bash*, *dash* or *tcsh*
|
|
shells and is also available as [Vim](http://www.vim.org/) plugin and
|
|
[IPython](http://ipython.org/) extension. For installation details, see
|
|
https://github.com/pavoljuhas/smart-change-directory.

```sh
|
|

|
|
scd -ar ~/Documents/
|
|
|
|
# Change to a directory path matching "doc"
|
|
scd doc
|
|
|
|
# Change to a path matching all of "a", "b" and "c"
|
|
scd a b c
|
|
|
|
# Change to a directory path that ends with "ts"
|
|
scd "ts$"
|
|
|
|
# Show selection menu and ranking of 20 most likely directories
|
|
scd -v
|
|
|
|
# Alias current directory as "xray"
|
|
scd --alias=xray
|
|
|
|
# Jump to a previously defined aliased directory
|
|
scd xray
|
|
```
|
|
|
|
# FILES
|
|
|
|
<dl><dt>
|
|
~/.scdhistory</dt><dd>
|
|
time-stamped index of visited directories.</dd><dt>
|
|
|
|
~/.scdalias.zsh</dt><dd>
|
|
scd-generated definitions of directory aliases.</dd>
|
|
</dl>
|

|
|
# ENVIRONMENT
|
|
|
|
<dl><dt>
|
|
SCD_HISTFILE</dt><dd>
|
|
path to the scd index file (by default ~/.scdhistory).</dd><dt>
|
|
|
|
SCD_HISTSIZE</dt><dd>
|
|
maximum number of entries in the index (5000). Index is trimmed when it
|
|
exceeds <em>SCD_HISTSIZE</em> by more than 20%.</dd><dt>
|
|
|
|
SCD_MENUSIZE</dt><dd>
|
|
maximum number of items for directory selection menu (20).</dd><dt>
|
|
|
|
SCD_MEANLIFE</dt><dd>
|
|
mean lifetime in seconds for exponential decay of directory
|
|
likelihood (86400).</dd><dt>
|
|
|
|
SCD_THRESHOLD</dt><dd>
|
|
threshold for cumulative directory likelihood. Directories with
|
|
a lower likelihood compared to the best match are excluded (0.005).
|
|
</dd><dt>
|
|
|
|
SCD_SCRIPT</dt><dd>
|
|
command script file where scd writes the final <code>cd</code>
|
|
command. This variable must be defined when scd runs in its own
|
|
process rather than as a shell function. It is up to the
|
|
scd caller to use the output in <em>SCD_SCRIPT</em>.</dd>
