This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.

Because of a bug, DOS time stamps from Level 0 and 1 headers after the year 2011 will be set to 1980, meaning that some utilities need to be patched. This is caused by a bug that interprets the unsigned 7-bit year number bitfield as a 5-bit number. The maximum year should be 2107 instead. [10] [11]
pax is an archiving utility available for various operating systems and defined since 1995. [1] Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of Unix, the IEEE designed a new archive utility pax that could support various archive formats with useful options from both archivers.
More commonly, the desired command names are linked (using hard or symbolic links) to the BusyBox executable; BusyBox reads argv[0] to find the name by which it is called, and runs the appropriate command, for example just /bin/ls. after /bin/ls is linked to /bin/busybox. This works because the first argument passed to a program is the name ...
The command syntax shows some characters in a mixture of upper and lower case. Abbreviating the command to only sending the upper case has the same meaning as sending the upper and lower case command. [3] For example, the command “SYSTem:COMMunicate:SERial:BAUD 2400” would set an RS-232 serial communications interface to 2400 bit/s.
The command lsb_release -a was available in many systems to get the LSB version details, or could be made available by installing an appropriate package, for example the redhat-lsb package in Red-Hat-flavored distributions such as Fedora, [4] or the lsb-release package in Debian-based distributions.
For example, in DOS 7.1, if the current directory is C:\WINDOWS\SYSTEM, then C:\WINDOWS\SYSTEM> TRUENAME ..\WIN.INI C:\WINDOWS\WIN.INI The argument does not need to refer to an existing file or directory: TRUENAME will output the absolute pathname as if it did.
