\b0 causes directory becomes the new working directory. The process must have execute (search) permission in directory. Because a new process is created to execute each command, cd would be ineffective if it were written as a normal command. It is therefore recognized and executed by the shells. In csh(1) you may specify a list of directories in which directory is to be sought as a subdirectory if it is not a subdirectory of the current directory; see the description of the cdpath variable in csh(1).

\b ls
\b0 lists the contents of the directory; for each file argument,
\b ls
\b0 repeats its name and any other information requested. By default, the output is sorted alphabetically. When no argument is given, the current directory is listed. When several arguments are given, the arguments are first sorted appropriately, but file arguments are processed before directories and their contents.

\b0 creates the specified directories; the directories are assigned the default access mode, which is determined by the umask(2) file creation mode mask. Standard entries, `.', for the directory itself, and `..' for its parent, are made automatically. Mkdir requires write permission in the parent directory.

\b0 creates the directories specified in each dir_path, and optionally sets owner, group, and mode for the created directories. Mkdirs requires write permission in the parent directory. Unlike mkdir, mkdirs creates all non-existent directories specified in each dir_path. For example, the following command creates both new-dir-1 and new-dir-2: mkdirs ~/new-dir-1/new-dir-2 The mode of the created directories is determined by the value of the mode argument, which may be absolute or symbolic (see chmod(1) for the correct syntax), or by the current umask(2) value if no mode argument is specified. Only modes of directories created by mkdirs are affected; modes of existing directories specified in the dir_path do not change.
\f0\b0\i0\ulnone\ql\fs24\fi0\li0\gray0\fc0\cf0\up0\dn0 A directory lost+found is created in the current directory and a number of empty files are created therein and then removed so that there will be empty slots for fsck(8). This command should not normally be needed since mkfs(8) automatically creates the lost+found directory when a new file system is created.
