Xiaobian to share with you what are the practical Linux Shell commands, I believe most people do not know how, so share this article for everyone's reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

1 Create pdf version for man manual

man -t manpage | ps2pdf - filename.pdf

For example, make ls command man manual pdf file

man -t ls | ps2pdf - ls.pdf

2 is a command binding shortcut key

bind -x '"\C-l":ls -l'

Press CTRL+L to list directories. You can add this command to ~/.bashrc so you don't have to repeat it every time.

3 One-click start tmux on remote host

tmux is an alternative to GNU Screen, a tool that can open multiple windows in the terminal. It can be said to be a very good remote service maintenance tool. You can directly open tmux on the remote server with the following command in the terminal.

ssh -t username@server.com tmux

If you have tmux turned on previously on the remote host, use the following command.

ssh -t username@server.com tmux att

In addition, you can combine the second command to bind the shortcut key, so that we can quickly log in and turn on tmux with one click.

4 Use the file command to view device information

file -s /dev/sd*

5 Compare the consistency of two files with md5 value

cmp file1 file2

If they are consistent, there will be no prompt. If they are inconsistent, there will be prompt information.

6 One command to make CD/DVD ISO file

dd if=/dev/cdrom of=file.iso

7 Copy entire hard disk to remote directory via ssh (with compression)

dd if=/dev/sda | gzip -c | ssh user@ip 'dd of=/mnt/backups/sda.dd'

8 Testing Network Speed Without Wasting Disk

dd if=/dev/zero bs=4096 count=1048576 |ssh user@ip 'cat > /dev/null' The above is "What are the useful Linux Shell commands?" All the contents of this article, thank you for reading!
