Some fzf functions which might be useful for your bashrc.
They provide "fuzzy" variants of popular commands such as cd, ls, vim, cat, firefox, chromium, grep, head, tail, evince, vlc, ...
If you consider the bash completion provided by fzf a bit clumsy, this is for you!
- support for Favorites
- user-based or global customization
- extensible
- implementation via bash aliases
- automatic dependency checks
- reasonable defaults
- small & fast (thanks to fzf!)
- Move the
bashrc_fzffile to a directory of your liking, let's say/etc/. - Import the
bashrc_fzfcontent into your local or globalbashrc, e.g. viasource "/etc/bashrc_fzf". - Optional: Create your own configuration at
~/.bashrc_fzf(user-based) or inside the aforementioned directory, e.g./etc/bashrc_fzf.conf(global). See the customization section for further details.
GNU coreutils and of course fzf. They are packaged by most Linux distributions.
Installed aliases may introduce [further dependencies](#installed aliases).
By default, the aliases have the same name as the original command, followed by a single f (for "fuzzy").
Exceptions are: ls --> lf, mpc --> f, $EDITOR --> e, firefox --> fox or firefoxf
All names can be changed (cf. customization).
The aliases will not be enabled, if any of their dependencies are not installed. So if you e.g. don't have mpc installed, f won't exist. In particular most default aliases depend on (m)locate. So either install it, or customize your configuration to make bashrc_fzf use something else.
cdf courage
Switch to a directory with courage in its file path. If a file is matched, go to the parent directory of that file.
e
Let the user decide from all files in his home directory which one to open with his $EDITOR. If (s)he presses Ctrl-C, just open the editor.
evincef bash cool
Attempt to find a pdf file with both the terms bash and cool in your home directory. If a match is found, open it. If no match is found, pass the parameters to evince as is (will likely cause some errors).
shuff love songs | tail -n1 | f
Find a text file listing love songs in your home directory, extract a random one and play it with mpc.
grepf queen favs.txt | shuf | tail -n1 | f
Find all Queen songs in your list of favorite songs, pick a random one and play it (f queen would let you select from all of your Queen songs). Alternatively, you could customize the f command to know your favorite songs.
grepf cash favs.txt | fzf | f
Find all Johnny Cash songs in your list of favorite songs, interactively select the one you want to listen to and play it (if you can memorize your favorite songs, f cash does the trick as well...).
fox git
Visit github.com with firefox.
chromiumf "https://github.com/3hhh/"
Same as with chromium: Visit my github profile.
killf chromium
Send a termination signal to an open chromium instance. If there are multiple, select it from a list.
All customizations should be done in either ~/.bashrc_fzf or in the installation directory of bashrc_fzf in a file called bashrc_fzf.conf.
Customizations are implemented as standard bash code and usually involve redefining certain associative arrays declared inside bashrc_fzf.
The command libreofficef is too long for your liking. If so, add the following redefinition to your config file:
FZF_CMDS["lo"]="id:libreoffice"This makes libreofficef available as lo as well.
If you'd like to redefine all commands, just redeclare the associative array FZF_CMDS, e.g. as such:
#I just want libreofficef, cdf and grepf
declare -gA FZF_CMDS=(
["cdf"]="id:cd"
["grepf"]="id:grep"
["libreofficef"]="id:libreoffice"
)See the source code of bashrc_fzf for the list of available IDs/commands.
The aforementioned associative array used to define all bash aliases.
Associative array to define your favorite directories. The matching happens against the keys, but the values are passed to the final command. If you don't want to use that feature, just define identical keys and values.
Associative array to define your favorite files.
Associative array to define your favorite URLs.
Associative array defining which favorites are applied for which command. New types of Favorites could be defined here as well.
The fzf command to execute to resolve fuzzy arguments, if the Favorites did not apply.
The fzf command to execute to resolve fuzzy arguments with the Favorites.
Command to employ to find directories and files on your file system. By default, (m)locate is used. If you prefer find or fd or something else, change that here.
Command to employ to find processes on your system. By default, ps aux is used. If you don't like the output, change that here. You also might have to redefine FZF_PROC_PID.
Required to implement new commands. FZF_DEPS holds the dependencies, FZF_IMPL the actual implementation.
