Where is the `sdk` command installed for sdkman

Question

I just installed sdkman for installing grails on my machine (MacOS). When I run which sdk command I don't get any output. But when I run the sdk help command the shell is able to resolve it and give the right output. I checked all the directories mentioned in $PATH environment variable but I could not find any executable sdk. So my question is how is shell able to resolve the sdk command?

Note: I also checked in Ubuntu and I see the same behavior.

which is almost never the right command. Use type instead – Schleswigholstein

Thank you! Apparently its a function defined in a source file. – Adan

Answer 1

OK. So I found it out. As @that-other-guy mentioned in the comment above, I used type -a instead of which, which showed me that it was a function defined.

As you mentioned correctly "sdk" is not a command, its a declared function created by sdkman-main.sh (in ~/.sdkman/src) once called from ~/.sdkman/bin/sdkman-init.sh

This is the reason why the installation page of sdkman asks for appending the following steps in the .bash_profile which declares this function each time the bash profile is loaded :

#THIS MUST BE AT THE END OF THE FILE FOR SDKMAN TO WORK!!!

[[ -s "/home/dudette/.sdkman/bin/sdkman-init.sh" ]] && source "/home/dudette/.sdkman/bin/sdkman-init.sh"

This is also the reason "which" command doesn't pick it up as it checks for the installed commands on the linux PATH

Why must it be at the end of the file? Why can't I add other things to PATH after it? – Tautologism
