Short Descriptions

base32 Encodes and decodes data according to the base32 specification (RFC 4648)

base64 Encodes and decodes data according to the base64 specification (RFC 4648)

b2sum Prints or checks BLAKE2 (512-bit) checksums basename Strips any path and a given suffix from a file name basenc Encodes or decodes data using various algorithms cat Concatenates files to standard output‌‌‌

chcon Changes security context for files and directories

chgrp Changes the group ownership of files and directories

chmod Changes the permissions of each file to the given mode; the mode can be either a symbolic representation of the changes to make or an octal number representing the new permissions

chown Changes the user and/or group ownership of files and directories

chroot Runs a command with the specified directory as the / directory

cksum Prints the Cyclic Redundancy Check (CRC) checksum and the byte counts of each specified file

comm Compares two sorted files, outputting in three columns the lines that are unique and the lines that are common

cp Copies files

csplit Splits a given file into several new files, separating them according to given patterns or line numbers and outputting the byte count of each new file

cut Prints sections of lines, selecting the parts according to given fields or positions

date Displays the current time in the given format, or sets the system date

dd Copies a file using the given block size and count, while optionally performing conversions on it

df Reports the amount of disk space available (and used) on all mounted file systems, or only on the file systems holding the selected files

dir Lists the contents of each given directory (the same as the ls command)

dircolors Outputs commands to set the LS_COLOR environment variable to change the color scheme used by ls dirname Strips the non-directory suffix from a file name‌

du Reports the amount of disk space used by the current directory, by each of the given directories (including all subdirectories) or by each of the given files

echo Displays the given strings

env Runs a command in a modified environment

expand Converts tabs to spaces

expr Evaluates expressions

factor Prints the prime factors of all specified integer numbers

false Does nothing, unsuccessfully; it always exits with a status code indicating failure

fmt Reformats the paragraphs in the given files

fold Wraps the lines in the given files

groups Reports a user's group memberships

head Prints the first ten lines (or the given number of lines) of each given file

hostid Reports the numeric identifier (in hexadecimal) of the host

id Reports the effective user ID, group ID, and group memberships of the current user or specified user

install Copies files while setting their permission modes and, if possible, their owner and group

join Joins the lines that have identical join fields from two separate files

link Creates a hard link with the given name to a file

ln Makes hard links or soft (symbolic) links between files

logname Reports the current user's login name

ls Lists the contents of each given directory

md5sum Reports or checks Message Digest 5 (MD5) checksums

mkdir Creates directories with the given names

mkfifo Creates First-In, First-Outs (FIFOs), a "named pipe" in UNIX parlance, with the given names

mknod Creates device nodes with the given names; a device node is a character special file, a block special file, or a FIFO

mktemp Creates temporary files in a secure manner; it is used in scripts

mv Moves or renames files or directories

nice Runs a program with modified scheduling priority

nl Numbers the lines from the given files

nohup Runs a command immune to hangups, with its output redirected to a log file

nproc Prints the number of processing units available to a process

numfmt Converts numbers to or from human-readable strings

od Dumps files in octal and other formats

paste Merges the given files, joining sequentially corresponding lines side by side, separated by tab characters

pathchk Checks if file names are valid or portable

pinky Is a lightweight finger client; it reports some information about the given users

pr Paginates and columnates files for printing

printenv Prints the environment

printf Prints the given arguments according to the given format, much like the C printf function

ptx Produces a permuted index from the contents of the given files, with each keyword in its context

pwd Reports the name of the current working directory readlink Reports the value of the given symbolic link realpath Prints the resolved path‌‌

rm Removes files or directories

rmdir Removes directories if they are empty

runcon Runs a command with specified security context

seq Prints a sequence of numbers within a given range and with a given increment sha1sum Prints or checks 160-bit Secure Hash Algorithm 1 (SHA1) checksums sha224sum Prints or checks 224-bit Secure Hash Algorithm checksums‌‌

sha384sum Prints or checks 384-bit Secure Hash Algorithm checksums‌

sha512sum Prints or checks 512-bit Secure Hash Algorithm checksums

shred Overwrites the given files repeatedly with complex patterns, making it difficult to recover the data

sync Flushes file system buffers; it forces changed blocks to disk and updates the super block

tac Concatenates the given files in reverse

tail Prints the last ten lines (or the given number of lines) of each given file

tee Reads from standard input while writing both to standard output and to the given files

test Compares values and checks file types
