Linux/unix common commands used in work

Common commands used by Linux in normal work:

SCP is a file copy with security, SSH-based login. Easy to operate, for example, to copy the current file to a remote other host, you can command the following.

Scp/home/1.gif [email protected]:/home/root

You will then be prompted to enter the login password for the root user of the other 172.19.2.75 host, and then the CP and Ungzip are started.

If you want to reverse the operation, copy the file from the remote host to the current system, it is also very simple:

SCP [email protected]:/home/abc.gif /home/root

Find-name ap*-o-name may*/* Find files that start with an AP or May
