join: Merge Common Fields of Two Files
The join command merges lines of two sorted text files based on a specified common field and outputs the result to standard output. It functions similarly to a JOIN operation in databases, combining corresponding lines from each file to create new lines.
jq: Processing JSON Data
jq is a powerful tool for efficiently processing and transforming JSON data on the command line. It is used to filter, slice, map, and transform JSON data, making it easy to extract desired information even from complex JSON structures. It is frequently used with other commands via pipes (|).
less: Freely Explore Text File Content
The `less` command displays the content of text files page by page and is a powerful paginator that, unlike `more`, allows you to freely navigate file content forwards and backwards. It is useful for efficiently reading large files or log files.
meld: Visual File/Directory Comparison and Merging Tool
meld is a graphical user interface (GUI) tool used to visually compare and merge two or three files or directories. It is very useful for code reviews, checking changes before and after applying patches, and resolving version control conflicts.
more: View Text File Content Page by Page
The 'more' command is a 'Paginator' that displays the contents of a text file screen by screen. When the file content does not fit on a single screen, it allows the user to navigate through the content one page at a time.
nano: A Terminal-Based Text Editor
Nano is a simple and intuitive text editor used in terminal environments. Inspired by the Pico editor, it is designed to be easy for beginners to use. It provides basic text editing functions such as creating, editing, and saving files.
od: Output Octal/Hexadecimal Dump of Files
The `od` command outputs the contents of a file in various formats such as octal and hexadecimal. It is a traditional tool used to analyze the contents of binary files or to check for invisible special characters in text files. It provides similar functionality to `hexdump`.
paste: Merge lines of files
The paste command merges lines from one or more files, outputting them to standard output. By default, lines from each file are separated by a tab character. This command is useful for preprocessing tasks such as combining multiple data sources or aligning data based on specific columns.
patch: Apply Changes (Patches) to Files
The 'patch' command is used to apply changes to original files using patch files (.patch) generated by the 'diff' command. This tool allows for efficient modification of source code or updating configuration files.
pr: Format text files for printing
The pr command converts text files into a format suitable for printing. It offers various formatting features such as adding page numbers, headers, dates, splitting into multiple columns, or adjusting page length. It is commonly used to make text more readable in the terminal or before printing.
rev: Reverse a String
The rev command reads lines from standard input or a file, reverses the order of characters in each line, and outputs the result to standard output. It's a simple yet useful utility often used with pipes (|) to manipulate the output of other commands.
sdiff: Compare Two Files Side-by-Side
The sdiff command compares two files in parallel, outputting their differences side-by-side in two columns for easy visual inspection. Unlike the `diff` command, it clearly distinguishes common and differing parts visually.
