[SOLVED] What is mean by these linux commands

Raakh5 · 09-08-2015, 10:26 AM

Hello,

Code:

useradd 8618718235810     //user added
mkdir /home/8618718235810     //directory created


chown 8618718235810:8618718235810 /home/8618718235810
cp -r ~/tg  /home/8618718235810/
su 8618718235810
cd ~/tg && bin/telegram-cli

Can anybody please explain the above code?

Best regards

Line by line...

It creates a new user with the username "8618718235810" - which is a very odd username indeed
It creates a home directory for that new user
It changes the permissions of that directory to belong to the new user
It copies some directory called "tg" from root's home directory into this new user's home directory
It switches to the "8618718235810" user
It executes some file called telegram-cli located in ~/tg/bin in the new user's home directory

Code:

chown 8618718235810:8618718235810 /home/8618718235810

why this is written 8618718235810:8618718235810 in chown command? Is this command not enough to set permission "/home/8618718235810"

"/home/8618718235810" is not a command. It is the folder which permission you want to change and is used as argument for the chown command.

Because root created the directory "/home/8618718235810", it is then owned by root:root. For the user 8618718235810 to be able to login, this folder needs to be owned by him and his group (user:group).

If you don't understand, what a command is doing, type

Code:

man <command>

and in this case

Code:

man chown

into a terminal and read.
