Remove files (POSIX)
rm [-Rfir] [-d] [-l n] [-v] file...
QNX Neutrino, Microsoft Windows
If the POSIX_STRICT environment variable is defined, the utility ignores any previously specified -i options. See the note below.
If POSIX_STRICT is defined, the utility ignores any previously specified -f options. See the note below.
|Use the -R option with care, as it removes directories, subdirectories, and files. Using the -i option with -R adds a measure of safety by turning on interactive prompting before each file or directory is removed.|
The rm utility removes each specified file from a directory.
By default, rm refuses to remove any file that names a directory. This may be overridden with the -R or -r options. In any case, rm always refuses to remove the current working directory.
If a file operand has been specified but doesn't exist and the -f option hasn't been given, a message is written to the standard error output. If -f has been given, the error message isn't written. In either case, rm goes on to any remaining files specified on the command line.
The rm utility doesn't necessarily remove the file itself. A file may have more than one link; that is, it may be known by more than one name in the filesystem (see the ln utility for information on creating links). The rm utility breaks one such link; it dissociates the file from one name. If this is the only link, the file data becomes inaccessible and the file space is returned to the system for reuse. Otherwise, the data remains accessible via other names.
|Currently, if POSIX_STRICT is set, -f and -i are operationally
exclusive: the utility ignores all but the last instance of -i or -f.
For example, rm -i -f * uses force mode, while rm -f -i * uses interactive.
If POSIX_STRICT isn't set, -i makes rm use interactive mode,
whether or not you specified -f.
In a future release, rm's default behavior will be changed to the POSIX behavior. To be sure that scripts, etc. work correctly with both current and later versions, either run rm with POSIX_STRICT set, or don't use -f and -i together.
Remove the a.out and core files:
