The zero flag is typically abbreviated Z or ZF or similar in most documentation and assembly languages. Along with a carry flag, a sign flag and an overflow flag, the zero flag is used to check the result of an arithmetic operation, including bitwise logical instructions. It is set to 1, or true, if an arithmetic result is zero, and reset ...
The test command in Unix evaluates the expression parameter. In most recent shell implementations, it is a shell builtin, even though the external version still exists.In the second form of the command, the [ ] (brackets) must be surrounded by blank spaces (this is because [is a program and POSIX compatible shells require a space between the program name and its arguments).

According to Samuel Eliot Morison, the Z flag flown at Pearl Harbor was the actual one used at Tsushima. [7] However, the Tōgō Shrine in Tokyo claims that its Z flag is Togo's original, having been stored in England from 1911 to 2005. [12] [better source needed] From 1905 to 1945, the Z flag was used as an unofficial naval ensign.
An MS-DOS command line, illustrating parsing into command and arguments. A command-line argument or parameter is an item of information provided to a program when it is started. [23] A program can have many command-line arguments that identify sources or destinations of information, or that alter the operation of the program.
For example a je (Jump if Equal) instruction in the x86 assembly language will result in a jump if the Z (zero) flag was set by some previous operation. A command line switch is also referred to as a flag. Command line programs often start with an option parser that translates command line switches into flags in the sense of this article.
chattr is the command in Linux that allows a user to set certain attributes of a file. lsattr is the command that displays the attributes of a file.. Most BSD-like systems, including macOS, have always had an analogous chflags command to set the attributes, but no command specifically meant to display them; specific options to the ls command are used instead.
