copying files on ubuntu

[wildrabbitt]

What does "uname -a" give when running tiny core?

Linux box 3.16.6-tinycore64 #777 SMP Thu Oct 16 10.:21:00 UTC 2014 x86_64 GNU/Linux

What does "ls -l mprime" give?What does "ls -l mprime" give?

-rwxr-xr-x 1 root root 35888675 Nov 22 2015 mprime

I'll now ask again, what does "pwd" say to you?

/mnt/sdb1/mprime_folder

Doesn't "locate" require a indexing to occur -- admittedly this would not take long for tiny core if it has such a feature.

Better might be "find ~/ -name mprime".

wildrabbitt knows where mprime is. If he "cd" (change directory) to the right directory and runs "./mprime -m" that should do it. (Is "-m" defunct?)

Yes. Locate requires a file-system wide index.

Possibly. Or perhaps "find / -name mprime" of the mprime directory was not in the user's home directory.

His name is "Wildrabbit", not "Woldrabbit".

But, yes, generally you are correct.

Attempting to be more helpful, I have tried/discovered the following, of which you more learned can say, "Of course!"

If I copy mprime to a USB drive, I am not allowed to run it, because it is not executable. Also, I am not "allowed" to make it executable, presumably due to me not "owning" the USB drive. I also could not change the permissions or run it as root.

Edit: I did, however find it using the "find / -name mprime" command, however, only after finding it this way as root. My initial try as 'user' did not locate it on the USB drive. Subsequent tries work.

Just in case, even though this is not a part of your current problem:
this above (root @) in itself will breed a host of other problems, so you better abandon this practice early in your learning curve. Don't log in as root (obviously unless you need that for indeed root activities). Don't leave root shells open. Best practice is to sudo, for most everyday patches and tweaks. It is best to stick to this habit early, like, you know, flossing ...or not texting-and-driving.

[paulunderwood]

To add to Batalov's run-as-william advice: you can change the ownership of mprime as root with:

chown william:william mprime

[wildrabbitt]

Thanks Paul. The thing is. My username was william on the ubuntu box I used to copy the mprime files to the stick on.

On tinycore64 I don't have a username

[paulunderwood]

You might need to run "adduser william"

so it looks like I haven't got the command file to use for some reason.

This means there is no `file` command on your system. (How has no one noticed this? Aren't there supposed to be experts in this thread? )

As for why `./mprime` fails, I have no idea.

To give us a feel for what the operating system does come with, try the following and post the outputs:

`which file` (this one should have no output I believe)
`echo $PATH`

[wildrabbitt]

thanks

no ouput for

'which file'

echo $PATH

produces

/home/tc/.local/bin:/usr/local/sbin:/usr/local/bin:/apps/bin:/usr/sbin:/usr/bin:/sbin:/bin

[Dubslow]

What about "echo $SHELL" ?

What about "/mnt/sdb1/mprime_folder/mprime" ? As chalsall says that should be equivalent to "./mprime" but I want to be sure...
