This searches the current working directory tree for files whose names start with my. The single quotes avoid the shell expansion—without them the shell would replace my* with the list of files whose names begin with my in the current working directory. In newer versions of the program, the directory may be omitted, and it will imply the ...
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
dirname is a standard computer program on Unix and Unix-like operating systems.When dirname is given a pathname, it will delete any suffix beginning with the last slash ('/') character and return the result.
A valid file URI must therefore begin with either file:/path (no hostname), file:///path (empty hostname), or file://hostname/path. file://path (i.e. two slashes, without a hostname) is never correct, but is often used. Further slashes in path separate directory names in a hierarchical system of directories and subdirectories. In this usage ...
Inodes do not contain their hard link names, only other file metadata. Unix directories are lists of association structures, each of which contains one filename and one inode number. The file system driver must search a directory for a particular filename and then convert the filename to the correct corresponding inode number.
Within a single directory, filenames must be unique. Since the filename syntax also applies for directories, it is not possible to create a file and directory entries with the same name in a single directory. Multiple files in different directories may have the same name.
Each directory is a list of directory entries. Each directory entry associates one file name with one inode number, and consists of the inode number, the length of the file name, and the actual text of the file name. To find a file, the directory is searched front-to-back for the associated filename. For reasonable directory sizes, this is fine.
In Research Unix, this was one file rather than a directory. [14] Nowadays usually on the root filesystem itself, unless the system, bootloader etc. require otherwise. /dev: Stands for devices. Contains file representations of peripheral devices and pseudo-devices. See also: Linux Assigned Names and Numbers Authority. Needs to be on the root ...
