In Unix-like operating systems such as Linux, \u201ceverything is a file<\/a>\u201d and a file is fundamentally a link to an inode (a data structure that stores everything about a file apart from its name and actual content).<\/p>\n

A hard link is a file that points to the same underlying inode, as another file. In case you delete one file, it removes one link to the underlying inode. Whereas a symbolic link (also known as soft link) is a link to another filename in the filesystem.<\/p>\n

Another important difference between the two types of links is that hard links can only work within the same filesystem while symbolic links can go across different filesystems.<\/p>\n

How to Create Hard Links in Linux<\/h3>\n

To create a hard links in Linux, we will use\u00a0ln utility<\/strong>. For example, the following command creates a hard link named\u00a0tp<\/code>\u00a0to the file\u00a0topprocs.sh<\/code>.<\/p>\n

$ ls -l\r\n$ ln topprocs.sh tp\r\n$ ls -l\r\n<\/pre>\n
\n
\"Create<\/a><\/p>\n
Create a Hard Link to File<\/p>\n<\/div>\n
Looking at the output above, using\u00a0ls command<\/a>, the new file is not indicated as a link, it is shown as a regular file. This implies that\u00a0tp<\/code>\u00a0is just another regular executable file that points to the same underlying inode as\u00a0topprocs.sh<\/code>.<\/p>\n
To make a hard link directly into a soft link, use the\u00a0-P<\/code>\u00a0flag like this.<\/p>\n
$ ln -P topprocs.sh tp\r\n<\/pre>\n
How to Create Symbolic Links in Linux<\/h3>\n
To create a symbolic links in Linux, we will use same\u00a0ln utility<\/strong>\u00a0with\u00a0-s<\/code>\u00a0switch. For example, the following command creates a symbolic link named\u00a0topps.sh<\/code>\u00a0to the file\u00a0topprocs.sh<\/code>.<\/p>\n
$ ln -s ~\/bin\/topprocs.sh topps.sh\r\n$ ls -l topps.sh\r\n<\/pre>\n
\n
\"Create<\/a><\/p>\n
Create a Symbolic Link to File<\/p>\n<\/div>\n
From the above output, you can see from the file permissions section that\u00a0topps.sh<\/code>\u00a0is a link indicated by\u00a0l:<\/code>meaning it is a link to another filename.<\/p>\n
If the symbolic link already exist, you may get an error, to force the operation (remove exiting symbolic link), use the\u00a0-f<\/code>\u00a0option.<\/p>\n
$ ln -s ~\/bin\/topprocs.sh topps.sh\r\n$ ln -sf ~\/bin\/topprocs.sh topps.sh\r\n<\/pre>\n
\n
\"Forcefully<\/a><\/p>\n
Forcefully Create Symbolic Link<\/p>\n<\/div>\n
To enable verbose mode, add the\u00a0-v<\/code>\u00a0flag to prints the name of each linked file in the output.<\/p>\n
$ ln -sfv ~\/bin\/topprocs.sh topps.sh\r\n$ $ls -l topps.sh\r\n<\/pre>\n
