I am actually cheating! I use an Apple iMac - which uses - I am told a version of Linux.
I am having a truck load of trouble installing drivers. To explain is a bit long winded - but I will try to cut it short.
I am using an Anet A8 3D printer - using Repetetier HOST software to control the printer. I am no techie but it seems the Anet makers use a com as a USB port of a com port as a USB port. I am sure you know which.
Snag is dea,ing with cloned Chinese stuff which started out life as Arduino code and got messed about on its life span. I did get the drivers installed - but had problems - I contacted Repetier - who are pushing a "Server" version ie its run from a browser - which uses a com port and which wiped out me drivers. I have found a set of code fo rthe terminal and its removed ( as far as I can see) all the server files. But - I still cannot install the drivers.

This may explain: sh: ls/dev/tty*: No such file or directory
sh-3.2# ls /dev/tty*

During installs - I install close down , cold boot. nothing.

www.repetier.com if its needed. Drivers are CH341 and CH34x 1.3

Apologies if I am in the wrong place but nobody else has a clue about a cure.

Welcome to this forum.

The right command is (see the space between ls and /dev/tty*):the effect of this command is to LiSt the devices whose names begins in tty (tty stands from teletype writer but in modern times designates the "virtual terminals", in other words the screen and associated keyboard from where you type the commands).

But if instead you typethe program (called a shell) that interprets the command you type tries to find a command called ls/dev/tty*. There is none, hence the error message. So, don't forget the space between ls and /dev/tty*.

Sorry, no. Apple Mac OS is *NOT* a version of Linux.
I find it hard to believe that the people at the Repetier site have no clue about installing their own software. There are Mac versions of everything they have on their site..that's what you need to download, then read/follow the instructions (also from their site), about installing on Mac.

Macintoshes use OS/X®, which is based Darwin®, an also-open-source variant of BSD® Unix®.

... not Linux®.

In fact, the two operating systems share no fundamental source-code in common, although both kernels are open-source and actively maintained.

Thanks for all replies and suggstions.....
After a lot of searching around and finding nobody seems to have had this problem or "gone public" with it if they had - and after a lot of Google busting stufff...
I found this - PL2303_MacOSX_v1.6.0_20151022

Its a "bridge"apparently between USB and serial.... and it worked for me - at least with one driver - when I trued the "original" comes in the box with the kit - it did not either replace or add the driver to the list available!

But its sorted my problem and teh 3D printer is running OK via a USB connection.

Sorry... I find it hard to believe that you think I did not do this to start off with??

I find it equally hard to believe that posting the same problem on their own forum did not get a solution from their forum rep.
It is ( now was) an Apple issue and I CAN understand that Repetier may not have expertise in that area other then the programming. AND has it seemed local to my machine - how could they offer anything other than what is considered the norm for such issues.

I found a solution see my last post.....

We have absolutely NO IDEA what you have done/tried, until you actually tell us, do we?
That's a problem with their company, then.
Great.
