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.
This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.
stat command line. stat() is a Unix system call that returns file attributes about an inode. The semantics of stat() vary between operating systems. As an example, Unix command ls uses this system call to retrieve information on files that includes: atime: time of last access (ls -lu) mtime: time of last modification (ls -l)
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.
BusyBox is a software suite that provides several Unix utilities in a single executable file.It runs in a variety of POSIX environments such as Linux, Android, [8] and FreeBSD, [9] although many of the tools it provides are designed to work with interfaces provided by the Linux kernel.
It includes all commands that are standardized by the Internet Engineering Task Force (IETF) in RFC 959, plus extensions. Note that most command-line FTP clients present their own non-standard set of commands to users. For example, GET is the common user command to download a file instead of the raw command RETR.
The H08A has a smaller 14-bit ROM space and 11-bit RAM space (vs. up to 20 and 12 bits on the PIC18), but it is not clear if this is an architectural limit or just that of current products. The H08A is missing the PIC18 PUSH , [ 30 ] DAW , TBLWR , CALLW , RESET , MOVF , SUBFWB , and NEGF instructions.
