One such example script was a CGI program called PHF that implemented a simple phone book. In common with a number of other scripts at the time, this script made use of a function: escape_shell_cmd(). The function was supposed to sanitize its argument, which came from user input and then pass the input to the Unix shell, to be run in the ...
The ln command is a standard Unix command utility used to create a hard link or a symbolic link (symlink) to an existing file or directory. [1] The use of a hard link allows multiple filenames to be associated with the same file since a hard link points to the inode of a given file, the data of which is stored on disk.

The ln shell command normally uses the link [7] system call, which creates a hard link. When the ln -s flag is specified, the symlink() system call is used instead, creating a symbolic link. Symlinks were introduced in 1982 in 4.1a BSD Unix from U.C. Berkeley. [8] The following command creates a symbolic link at the command-line interface (shell):
