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.
In computing, a symbolic link (also symlink or soft link) is a file whose purpose is to point to a file or directory (called the "target") by specifying a path thereto. [ 1 ] Symbolic links are supported by POSIX and by most Unix-like operating systems , such as FreeBSD , Linux , and macOS .
Junction points are NTFS reparse points and operate similarly to symbolic links in Unix or Linux, but are only defined for directories, and may only be absolute paths on local filesystems (as opposed to remote filesystems being accessed). They are created and behave in a similar way to hard links, except that if the target directory is renamed ...
An NTFS reparse point is a type of NTFS file system object. It is available with the NTFS v3.0 found in Windows 2000 or later versions. Reparse points provide a way to extend the NTFS filesystem. A reparse point contains a reparse tag and data that are interpreted by a filesystem filter driver identified by the tag.
Selenium Remote Control was a refactoring of Driven Selenium or Selenium B designed by Paul Hammant, credited with Jason as co-creator of Selenium. The original version directly launched a process for the browser in question, from the test language of Java, .NET, Python or Ruby.
An attacker must create the link in the interval between the check and when the file is created. A symlink race can happen with antivirus products that decide they will quarantine or delete a suspicious file, and then go ahead and do that. During the interval between decision and action, malicious software can replace the suspicious file with a ...
In particular, the POSIX specification and the Linux man page signal (7) require that all system functions directly or indirectly called from a signal function are async-signal safe. [ 6 ] [ 7 ] The signal-safety(7) man page gives a list of such async-signal safe system functions (practically the system calls ), otherwise it is an undefined ...
