How to make a mount permanent by editing /etc/fstab?
The method to automatically mount disk partitions in Linux is to edit the /etc/fstab file. Each line of the file contains six fields: 1) filesystem (it is recommended to use a UUID instead of a device name to ensure stability); 2) mountpoint (specify the mount directory such as /mnt/data); 3) type (file system type such as ext4); 4) options (mount options such as defaults); 5) dump (replacement generally fills in 0 for backup flags); 6) pass (fsck check order root partition is 1, others are 2 or 0). Operation steps include: 1) Use blkid to confirm device information; 2) Create a mount directory such as sudomkdir/mnt

How to compile and install software from source code?
The core steps of compiling and installing software are: download source code, decompression, configuration, compilation, and installation. First, prepare the environment and dependencies, such as the gcc compiler, make tools and development libraries, and use the corresponding commands to install the basic tools in different systems; then download the source code package from the official website or GitHub and decompress it to the working directory, enter the decompressed directory to run ./configure to configure the environment and generate Makefile; then execute the make command to compile, and use sudomakeinstall to install the software after completion; after installation, you may need to manually add environment variables to run, and write the path to the .bashrc or .zshrc file to make it permanent.

How to change the owner of a file or directory using chown?

How to sort the output of a command?
In Linux, the command output can be passed to sort commands through pipelines. The basic format is command|sort. For example, ls-l|sort can sort the file list alphabetically, and ls-lh|sort-k5 can sort according to file size; if numerical sorting is required, if the process is sorted by CPU usage, psaux|sort-nk3 can be used, and the -r parameter can be added to the descending order; for custom sorting, you can specify the field separator through -t and specify the sorting field, such as cut-d:-f1,3/etc/passwd|sort-t:-k2 can sort the username and UID information by user ID, and support multi-field sorting, such as sort-
