Hi
I'm wondering, how come i've got to start my program with ./myapp,
when f.ex Git starts without ./ ?!?
What's the difference, is there some option/parameter that I can add
or adjust? 
Regards Benny

No place. GIT is in a directory in the $PATH and your binary not.

Create a deb package for you application. After install, you can start
it from a terminal by typing the package name, without "./".

Another practical trick:

I create a ~/bin that I put in the path (editing .bashrc).

Then I create symlinks for projects that I'm working on from the bin
directory to the binary I want to run. This means the live version of
the binary remains in the project dir (for easy
editing/testing/updating), but allows executing without path.

Hi
@ getmem: my PCLinuxOS works with rpm's, and I think it's a bit
overkill for my apps 
@ marcov:
  1)  That makes perfectly sense, thank you.
  2)  Cool trick, i'll use that. 

Thank you very much guys 
Regards Benny

The reason is that, unlike e.g. Windows, most *nixen don't look in the
current directory for the executable, only in the PATH. If a program
is not installed in any of the directories in the PATH you have to
tell the system where it is in the invocation.

I think most of us on Linux do that; it's extremely handy. We run all
of our internal tools that way

Another "trick" is to link from /usr/bin/ (or any "bin" folder, in
fact) though that usually requires being root. It's, for example, how
startlazarus is invoked:
Code: Bash  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i $ ls -l
/usr/bin/startlazaruslrwxrwxrwx 1 root root 38 jul  7  2020
/usr/bin/startlazarus -> /usr/share/lazarus/2.0.10/startlazarusand
it's used mostly for multi-user installs.
