but all hardlinks to a file must reside on the same

[filesystem](../dict/terms/filesystem.md) as the file itself!

What you usually call a file is just a name for that file, and thus, a
hardlink.

The difference between a [symbolic link](../dict/terms/symlink.md) and a hard
Convert files under dict to Markdown

link is that there is no easy way to differentiate between a \'real\'
format(docs): remove escaped 's character pairs
2024-03-30 19:22:45 +01:00
file and a hard link, let's take a look at the example:

\* create an empty file
$ touch a
\* create a hard link \'b\' and sym link \'c\' to empty file
$ ln a b
$ ln -s a c
as you can see file(1) can\'t differentiate between a real file \'a\'
and a hard link \'b\', but it can tell \'c\' is a sym link
$ file *
a: empty
b: empty
c: symbolic link to `a'
`ls -i` prints out the inode numbers of files, if two files have the
same inode number AND are on the same file system it means they are
**hardlinked**.
$ ls -i *
5262 a 5262 b 5263 c
hard links don\'t consume additional space on the filesystem, the space
is freed when the last hard link pointing to it is deleted.
