so I am fairly new to linux and trying to figure out its ins and outs, I noticed that installed software behave differently, in such way that for example on my OpenSUSE I have both softwares OpenFOAM and MATLAB... In my .bashrc aliases, Openfoam has following alias
alias OF='source /..../bashrc' but matlab alias os as follows
alias matlab='/opt/..../matlab' which means matlab has an execuatable and openfoam just a bash script to run it...
my question is, why is it two different ways of running the softwares?
P.S: I havent installed the software myself, they were already there.
