A faster way to cd to commonly used directories inspired by commacd. Tested on
|
||||||
|
Bash 5.1, but should work on most versions.
|
||||||
|
|
||||||
|
Installation
|
||||||
|
************
|
||||||
|
|
||||||
|
On most operatin systems with Bash run:
|
||||||
|
|
||||||
|
$ curl -o ~/.goto.sh \
|
||||||
|
-sSL https://gitea.gch.icu/ge/goto/raw/branch/master/goto.sh
|
||||||
|
$ echo '[ -f ~/.goto.sh ] && . ~/.goto.sh' >> ~/.bashrc
|
||||||
|
|
||||||
|
Reread ~/.bashrc by command:
|
||||||
|
|
||||||
|
$ source ~/.bashrc
|
||||||
|
|
||||||
|
Usage
|
||||||
|
*****
|
||||||
|
|
||||||
|
Available commands (actually is aliases to functions):
|
||||||
|
|
||||||
|
s [<path>] bookmark $PWD or <path> (save into ~/.gotosave).
|
||||||
|
g [<pattern>] goto directory. If you have only one bookmark dir will be
|
||||||
|
changed without prompt. Type dir number in prompt to cd.
|
||||||
|
|
||||||
|
Run `g` to show the entire list of bookmarks and select the one you need.
|
||||||
|
|
||||||
|
You don't even need to press `Enter` to confirm your selection -- just type in
|
||||||
|
the bookmark number. The exception is when you have a two-digit number (or more)
|
||||||
|
and you select a bookmark whose number is less than 10. Then you have to press
|
||||||
|
`Enter`.
|
||||||
|
|
||||||
|
You can pass the Perl regular expression (processed by grep -Pi) as an for 'g'.
|
||||||
|
At the same time, if only one bookmark is found, then the directory will be
|
||||||
|
changed directly to it. If there are several bookmarks, you will be prompted to
|
||||||
|
choose the appropriate one. Also you can use autocompletion by pressing `Tab`.
|
||||||
|
It works in a similar way.
|
||||||
|
|
||||||
|
Examples
|
||||||
|
--------
|
||||||
|
|
||||||
|
Previously set up your commonly used dirs. Specify dir as argument:
|
||||||
|
|
||||||
|
$ s ~/Documents
|
||||||
|
$ s ~/Downloads
|
||||||
|
|
||||||
|
or cd into dir and simply run
|
||||||
|
|
||||||
|
$ s
|
||||||
|
|
||||||
|
Goto directory by number:
|
||||||
|
|
||||||
|
$ g
|
||||||
|
0 ~/Documents/
|
||||||
|
1 ~/Downloads/
|
||||||
|
: <type number here, e.g. 1>
|
||||||
|
=> cd /home/user/Downloads
|
||||||
|
|
||||||
|
Goto '~/Downloads' directory by regex:
|
||||||
|
|
||||||
|
$ g w
|
||||||
|
=> cd /home/user/Downloads
|
||||||
|
|
||||||
|
Another way :)
|
||||||
|
|
||||||
|
$ g 'do[^c]'
|
||||||
|
=> cd /home/gd/Downloads
|
||||||
|
|
||||||
|
and etc.
|
||||||
|
|
||||||
|
Tips
|
||||||
|
****
|
||||||
|
|
||||||
|
Combining commacd, goto and Bash autocd option gives a great experience!
|
||||||
|
|
||||||
|
Add to you ~/.bashrc following:
|
||||||
|
shopt -s autocd
|
||||||
|
Now you can type just directory name without 'cd' to change directory.
|
||||||
|
|
||||||
|
Get commacd here: https://github.com/shyiko/commacd

||||||
