This article will explain in detail how to mark Linux commands. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Mark the Linux command

We can tag some complex commands that remind you of the purpose of the Linux command. After applying tags to Linux commands, we don't have to enter long and complex commands, we just need to enter the tag characters we set up to OK!

Let's demonstrate a command, such as finding and listing files greater than 10MB in the current directory, and sorting them by size:

$find. -size + 10m-type f-print0 | xargs-0 ls-Ssh | sort-z

I wonder if you remember what this order is for? If you don't remember, part of it will be taken apart and analyzed by yourself.

Because it is too long to see the effect at a glance, we can add a memorable mark at the end of it, preferably reflecting the function of the command, such as setting ListFilesBiggerThanXSize here:

$find. -size + 10m-type f-print0 | xargs-0 ls-Ssh | sort-z # ListFilesBiggerThanXSize

Note: start with # and there is a space between the command and the label name.

Try the effect quickly and enter the tag you just saw:

$! # ListFilesBiggerThanXSize

Over here, Jack! And? Operator is used to get and run the commands we previously marked from the BASH history.

[alvin@VM_0_16_centos] $find. -size + 10m-type f-print0 | xargs-0 ls-Ssh | sort-z # ListFilesBiggerThanXSize total 104K 16K httpd.c 16K shakespeare 12K hello 4.0K dir2 [alvin@VM_0_16_centos ~] $!? # ListFilesBiggerThanXSize find. -size + 10m-type f-print0 | xargs-0 ls-Ssh | sort-z # ListFilesBiggerThanXSize total 104K 16K httpd.c 16K shakespeare 12K hello 4.0K dir2

Another way

Another method of memory is "nickname", that is, the use of alias command, we should be familiar with, the principle is similar to marking.

For example, give us a nickname for the above command:

$alias ListFilesBiggerThanXSize='find.-size + 10m-type f-print0 | xargs-0 ls-Ssh | sort-z'

Enter directly when using:
