Minix 3: add new command

Question

I'm currently trying to add a new command to Minix. I want to add a command named smile, which I want to display continuously a smiling face :-)the same way the command yes do with y.

I already created the smile dir in src/commands, with smile.c and Makefile, and added smile to src/commands/Makefile. But after compiling I still get

# smile
smile: not found

Is there another file/header/script where I must add a reference to smile?

Thank you in advance!

what did you do to resolve the issue? How did you generate the executable for smile and move it to /usr/bin? — JRG, Oct 07 '17 at 06:46

You either need to specify the directory, or the directory must be part of the PATH environment variable.

Try

./smile

if the program is in the current directory.

or

export PATH=".:$PATH"
smile

to always check the current directory for commands during this bash session.

If the program is in a subdirectory (eg. src/commands/smile) relative to the current directory, you can add that to the path instead. Either explicitly,

src/commands/smile/smile

or by adding to the search path

export PATH="src/commands/smile:$PATH"
smile

I doesn't change anything :/ – HappyRave Nov 06 '13 at 11:49
Hmm. Maybe `setenv PATH ".:$PATH"` and `rehash`. – luser droog Nov 06 '13 at 11:52
What shell are you using? – luser droog Nov 06 '13 at 11:53
Hmm. `export` should work with bash. This adds the current directory to the search path. I found something that says the default shell is `ash`, but it may be historical. But `export` comes from `sh` and should work on all of them (except `csh`). – luser droog Nov 06 '13 at 11:59
Does the program get compiled in `src/commands`? Maybe you want to `export PATH="src/commands:$PATH"`. – luser droog Nov 06 '13 at 12:00
I think my error is somewhere else. I smile should show up in /usr/bin, but it's not here – HappyRave Nov 06 '13 at 12:09
Did you install it? Compiling does not generally install binaries to system locations (for good reason). – Etan Reisner Nov 06 '13 at 13:07
@EtanReisner You sir are completely right! Missed this part >< Thanks – HappyRave Nov 07 '13 at 12:17

placing your executable in the /usr/bin folder will allow the shell to recognize it. you should be able to type #smile now
