Fexl does not automatically install in /usr/bin. You simply download Fexl into your own local directory and use it from there.
Let's say I've installed Fexl in my own ~/code/fexl directory. Now I want to make it convenient to run a simple command "fexl" from anywhere. Because I have "~/bin" in my PATH environment variable, I can put the script there.
First I do this:
cd ~/bin touch fexl chmod +x fexl vi fexl
Then I put this into the script:
exec ~/code/fexl/bin/fexl "$@"
To test this, I went into my own ~/tmp directory and created a "hello.fxl" file with this code in it:
say "Hello." \show=(\list say (join " " list)) \list=(append ["f" "a" "c"] ["b" "d" "e"]) \list=(append list list) \list=(append list list) show list show (sort list) show (unique list)
Now I can run that script from anywhere, for example:
cd fexl tmp/hello.fxl
Here is the output:
Hello. f a c b d e f a c b d e f a c b d e f a c b d e a a a a b b b b c c c c d d d d e e e e f f f f a b c d e f
