lsattr: View File Attributes
The lsattr command lists the special attributes set on files in Linux ext2, ext3, and ext4 file systems. These attributes affect how files behave, separate from regular file permissions, and are typically set using the chattr command.
lsblk: Guide to Displaying Block Device Information
The lsblk command displays information about all block devices (hard disks, SSDs, USB drives, etc.) on the system in a tree-like format. It is useful for quickly understanding physical disk information such as device name, size, mount point, and type.
md5sum: Calculate and Verify File MD5 Checksums
The md5sum command is used to calculate and verify the MD5 (Message-Digest Algorithm 5) checksum of files. It is useful for checking file integrity or ensuring that a file has not been corrupted during transmission.
mkdir Command Guide: Create New Directories
`mkdir` command (make directory) is used in Linux and Unix-like operating systems to create new directories (folders). It is an essential command for organizing and tidying up the file system. Through this guide, learn the basic usage and useful options of the `mkdir` command.
mkfifo: Create a Named Pipe
`mkfifo` is a command used to create named pipes (FIFOs, First-In, First-Out). A named pipe is a special file that exists in the file system and acts as a communication channel for data exchange between different processes. Unlike regular pipes, named pipes can be accessed via a file path, making it easier for independent processes to communicate.
mktemp: Create Temporary Files/Directories
The mktemp command securely creates temporary files or directories with unique names. It is designed for use in scripts when temporary storage is needed, preventing name collisions and security issues.
mmv: Move/Copy/Link Multiple Files by Pattern
The mmv command is a tool used to move, copy, link, or rename multiple files based on specific patterns. It supports wildcard pattern matching similar to regular expressions, making it useful for batch processing a large number of files.
mv Command Guide: Moving/Renaming Files and Directories
`mv` command (move) is used in Linux and Unix-like operating systems to change the name of files or directories, or to move them to another location. It is an essential command for organizing and restructuring the file system. Through this guide, you will learn the basic usage of the `mv` command and its useful options.
pwd Command Guide: Check Current Working Directory
`pwd` command (print working directory) is used in Linux and Unix-like operating systems to display the full path of the directory you are currently working in. It is the simplest and most basic way to check your location within the file system. Use this guide to learn how to use the `pwd` command.
readlink Command Guide
`readlink` command is used to output the actual target path of a symbolic link. A symbolic link acts as a pointer to a file or directory, similar to a 'shortcut' in Windows. `readlink` is particularly useful when you need to accurately determine the original path of a symbolic link while scripting.
realpath: Get Real Path
The realpath command resolves symbolic links and removes redundant path components like '.' or '..' to output the absolute path of a file or directory. This is useful for accurately determining file locations in scripts or simplifying complex paths.
rename: Batch Rename Tool for Multiple Files
The `rename` command is used to change the names of multiple files at once using regular expressions. Unlike `mv`, it is very useful for batch modifying filenames based on patterns.
