The rm command removes references to objects from the filesystem using the unlink system call, where those objects might have had multiple references (for example, a file with two different names), and the objects themselves are discarded only when all references have been removed and no programs still have open handles to the objects.
Spaces and symbols such as a "/" or a "-" may be used to allow the command processor to parse the command line into filenames, file specifications, and other options. The command interpreter preserves the case of whatever parameters are passed to commands, but the command names themselves and file names are case-insensitive.
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.
Provides data about exactly the object named on its command line in a standardized machine-readable format. MODE RFC 959 Sets the transfer mode (Stream, Block, or Compressed). NLST RFC 959 Returns a list of file names in a specified directory. NOOP RFC 959 No operation (dummy packet; used mostly on keepalives). OPTS RFC 2389
A command prompt (or just prompt) is a sequence of (one or more) characters used in a command-line interface to indicate readiness to accept commands. It literally prompts the user to take action. A prompt usually ends with one of the characters $ , % , # , [ 18 ] [ 19 ] : , > or - [ 20 ] and often includes other information, such as the path ...
In the above example, the find utility feeds the input of xargs with a long list of file names. xargs then splits this list into sublists and calls rm once for every sublist. Some implementations of xargs can also be used to parallelize operations with the -P maxprocs argument to specify how many parallel processes should be used to execute the ...
The Call command allows subroutines within batch file. The Call command in COMMAND.COM only supports calling external batch files. File name parser extensions to the Set command are comparable with C shell. [further explanation needed] The Set command can perform expression evaluation. An expansion of the For command supports parsing files and ...
