cat, short for concatenate, is used to read, print and combine files. echo displays a line of text either on standard output or to place in a file. sed is a popular stream editor often used to filter and perform substitutions on files and text data streams. awk is a interpreted programming language typically used as a data extraction and reporting tool. sort is used to sort text files and output streams in either ascending or descending order. uniq eliminates duplicate entries in a text file. paste combines fields from different files and can also extract and combine lines from multiple sources. join combines lines from two files based on a common field. It works only if files share a common field. split breaks up a large file into equal-sized segments. Regular expressions are text strings used for pattern matching. The pattern can be used to search for a specific location, such as the start or end of a line or a word. grep searches text files and data streams for patterns and can be used with regular expressions. tr translates characters, copies standard input to standard output, and handles special characters. tee accepts saves a copy of standard output to a file while still displaying at the terminal. wc (word count) displays the number of lines, words and characters in a file or group of files. cut extracts columns from a file. less views files a page at a time and allows scrolling in both directions. head displays the first few lines of a file or data stream on standard output. By default it displays 10 lines. tail displays the last few lines of a file or data stream on standard output. By default it displays 10 lines. strings extracts printable character strings from binary files. The z command family is used to read and work with compressed files.
