Help on few problems...


1.

Write the command that shows encoding of all files listed in some directory /space.



2.

df output

/dev/hda5 5160576 2440404 2458028 50% /usr
/dev/hdb6 3096336 1147968 1791084 40% /usr/share

copy all files from file system that is on/dev/hda5 partition to /mnt/BACKUP, but without copying files from /dev/hdb6. What is the most optimal command to use for this task?



3.

What command is used for listing file attributes, and can we change the owner on file that has attribute 'i' ?




Thanx for help.

A few things for you to note, kim0.
  • Please use better subject lines. "Help on few problems..." provides no useful information at all. By posting decent subject lines you will attract more people who are better able to assist. It is in your own interest to do this, and into the bargain you will annoy less people.
  • Is this homework? It sure looks like home work. We are not here to do your homework for you. We will help if you ask properly, but just posting your homework questions is quite offensive, not to mention explicitly against the forums rules.
Now go and read your course notes and do your own homework. When you have an honest question, you are welcome back.

lin_myworld, you are not doing a favour to the OP: if this is homework (indeed it looks like copied/pasted questions) first he should try by himself. If someone put the correct solution in a nutshell, he never truly learn and he will never move his brain. Not to mention your replay is a bit off-topic, since he was talking about encoding, not file types!

@ matthewg42:

yes its my homework, and i didnt mean to offend anyone, I appologise on that.


@ lin_myworld:

1.

Write the command that shows encoding of all *.txt files listed in some directory /space.


Sorry, I forgot to write that *.txt in some dir /space.


I tried with this:

user@alas:~/public_html$ file space/*.txt

but i get this:

space/baja.txt: empty
space/jaja.txt: empty
space/kimo.txt: empty
space/sisa.txt: empty


and need to get something like

space/baja.txt: ASCII
space/jaja.txt: UTF-8
space/kimo.txt: ASCII
space/sisa.txt: ASCII

Indeed, this is a better attitude. For question number one you are on the right way, but the output you obtain is quite clear
Code:
space/baja.txt: empty
space/jaja.txt: empty
space/kimo.txt: empty
space/sisa.txt: empty
check the size of the files: they are empty. No character encoding to determine, since they don't contain any character.

Yeah, they are empty..
So i suppose command file /space/*.txt would write encoding if they were filled with some text?

If you can create a simple text file (you should already know the command "cat" or any text editor available on your system) you can test it. Also have a look at the manual page of "file": option -i can be useful in some cases.
