@overexchange I would glance over the code at least, and the test run carefully. "Verify" is a strong word that implies making absolutely sure that you always get the same output. You may want to do this, but start with test running the scripts and comparing outcomes. When the outcomes differ, that's when you need to start looking at what's going wrong.
... also "verify each line" may be overkill, unless it's handling really sensitive information. Testing and comparing results may be the best approach. Also try feeding the script invalid data.
@jsb Well, it looks like otherwise you'll have to set your LIB path and all sorts of things. If this is your own system, or you have root access, you can always install directly in /opt. Alternatively, and probably the simplest, add ~/bin to your PATH and then symlink the executable only: ln -s ~/bin/julia/julia ~/bin.
@jsb I also think you should ask a question on the main site, because if julia is itself an ELF binary and not a wrapper script (which your ldd confirms), and ~/bin/julia doesn’t work, adding ~/opt/julia-1.0.0/bin probably won’t either.
So it’s likely to involve a fair amount of back-and-forth, which should be done in question comments rather than chat ;-).
@terdon I think I already did what you suggested to do "alternatively". My symlink points from ~/opt/julia-1.0.0/bin/julia to ~/bin/julia and ~/bin is in my $PATH.
@jsb Ah, I though you had symlinked the dir, not the executable. But that's the sort of thing that makes it better to post a full question so all these details can be shown.
@Scorpion You should ask the people who voted to close, I didn't have anything to do with it. I would guess, however, that the main differences are: ifconfig is expected to be installed in CentOS7 by default, the OP of the second question included their PATH and wrote a clearer question.
@terdon also route is expected to be installed. They both are part of net-tools. The path in the end is pointless: I didn' t included it because I didn' t known why included it. Can you "open" the question?
@Scorpion Why don't you edit and clarify what's going on. For example, try to find out what package route comes from and if that package is installed. Or, if you think it should be there by default say it and ask why it isn't. As it stands, your question basically reads like "I tried to run some command and it wasn't found. Why?"
Which is very different to "I tried to run a command that should be installed by default but it wasn't found. This is my $PATH, there is no file of that name in any of my PATH directories, I have checked that the relevant package is installed so why isn't this working?"
Just as an example. Basically, your question is too broad: we have no way of knowing if the relevant package is installed, or if you deleted it by accident etc etc.
How can I add a module to a kernel? silead If in /drivers/platform/x86/ there isn' t the silead_dmi.c file i can add it, but when i' ll recompile the kernel the module .ko won't be created
@StephenKitt "asking a question is a privilege" and since my questions "are making worse the site" I cannot.,, I' m speechless

Dear @Kusalananda based on what I understood from what you explained to me on the different operations I published an answer. I ask you in a rare manner to review this (quite short and straightforward) answer and to help me explain why computational anding is not subtraction even though it's looks very much like it.
I also invite @StephenKitt to review and comment. I think I am very close to finally getting this concept and your help will be most welcome and most precious for me.
