# Some Shell Tricks

I use rc as my main shell. But you can interpret into any other sh
ell.

1. I made a "Show the current directory" script.


``````````````````````````````````````````````````````````````````
#!/usr/local/bin/rc

clear;pwd;lc
``````````````````````````````````````````````````````````````````


I named it 'l'.

Then I combined 'cd' with 'l'. You can also combine 'l' with 'mv',
'rm', &c. I just don't use in that way. In ~/.rcrc,


``````````````````````````````````````````````````````````````````
fn cd {builtin cd $*; l}
``````````````````````````````````````````````````````````````````


2. I made scripts to explore files. For that, I made two files. On
e contains directory names. The other contains file names.


``````````````````````````````````````````````````````````````````
#!/usr/local/bin/rc

bmdir = $HOME/bmdir.txt
bmfiles = $HOME/bmfiles.txt

find $HOME -type d >$bmdir
find $HOME -type f >$bmfiles
``````````````````````````````````````````````````````````````````


I named the script 'fu'. You can use your cache directory instead
of $HOME. But I use $HOME anyway. I restrict it in $HOME, but you
can use it on /. I added it as a cron job.


``````````````````````````````````````````````````````````````````
* * * * * $HOME/bin/fu
``````````````````````````````````````````````````````````````````


Then I made two scripts. One for files, and the other for director
ies. I named those 'f' and 'g'.


``````````````````````````````````````````````````````````````````
#!/usr/local/bin/rc

bmfiles = $HOME/bmfiles.txt

sel = `{cat $bmfiles | fzy}

v $sel
``````````````````````````````````````````````````````````````````


If you 'fzy $bmfiles', it doesn't show files in ~/.config. If you
will not edit config files, use in that way. 'v' is a general file
opener.

I made 'g' as a function in ~/.rcrc. If I made it as a seperate s
cript, it doesn't work. I don't know why.


``````````````````````````````````````````````````````````````````
fn g{
	bmdir = $HOME/bmdir.txt
	cd `{cat $bmdir | fzy}
}
``````````````````````````````````````````````````````````````````


This is 'v'.


``````````````````````````````````````````````````````````````````
#!/usr/local/bin/rc

switch($*) {
case *mp4 *mkv *webm *flv *ts *m4a *opus *mp3 *webp
mpv $*

case *jpg *jpeg *png *gif
sxiv $*

case *djvu *pdf *epub
zathura $*

case *txt *md *csv *html *js *json *conf *.c *.h *.mk *.info *.orig *.local [a-z]* /etc* *config* *rc
vi $*

case *
echo 'Not yet defined.'
}

``````````````````````````````````````````````````````````````````


[a-z]* is because I make directory names start with a capital lett
er. Also, I use mpv as an audio player. Since I often need the sup
eruser to edit files, I made 'dv' in ~/.rcrc.


``````````````````````````````````````````````````````````````````
fn dv {doas v $*}
``````````````````````````````````````````````````````````````````
