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 plugin and
IPython extension. For installation details, see
https://github.com/pavoljuhas/smart-change-directory.

SYNOPSIS

scd [options] [pattern1 pattern2 ...]

OPTIONS

-a, --add
add specified directories to the directory 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 save it to
~/.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.

--list


show matching directories and exit.

-v, --verbose


display directory rank in the selection menu.

-h, --help


display this options summary and exit.

Examples

# Index recursively some paths for the very first run
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

~/.scdhistory
time-stamped index of visited directories.

~/.scdalias.zsh


scd-generated definitions of directory aliases.

ENVIRONMENT

SCD_HISTFILE
path to the scd index file (by default ~/.scdhistory).

SCD_HISTSIZE


maximum number of entries in the index (5000). Index is trimmed when it
exceeds SCD_HISTSIZE by more than 20%.

SCD_MENUSIZE


maximum number of items for directory selection menu (20).

SCD_MEANLIFE


mean lifetime in seconds for exponential decay of directory
likelihood (86400).

SCD_THRESHOLD


threshold for cumulative directory likelihood. Directories with
a lower likelihood compared to the best match are excluded (0.005).

SCD_SCRIPT


command script file where scd writes the final cd
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 SCD_SCRIPT.
