ntpdate is a computer program used to quickly synchronize and set computers' date and time by querying a Network Time Protocol (NTP) server. It is available for a wide variety of unix-like operating systems.
v. t. e. The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable- latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware.
date: Prints or sets the system date and time dirname: Strips non-directory suffix from file name du: Shows disk usage on file systems echo: Displays a specified line of text env: Displays and modifies environment variables: expr: Evaluates expressions factor: Factors numbers: false: Does nothing, but exits unsuccessfully groups
In computing, touch is a command used to update the access date and/or modification date of a computer file or directory. It is included in Unix and Unix-like operating systems, TSC 's FLEX, [1] Digital Research / Novell DR DOS, the AROS shell, [2] the Microware OS-9 shell, [3] and ReactOS. [4] The command is also available for FreeDOS [5] and ...
chrony is an implementation of the Network Time Protocol (NTP). It is an alternative to ntpd, a reference implementation of NTP. It runs on Unix-like operating systems (including Linux and macOS) and is released under the GNU GPL v2. [4] It is the default NTP client and server in Red Hat Enterprise Linux 8 and SUSE Linux Enterprise Server 15 ...
rsync. rsync (r emote sync) is a utility for transferring and synchronizing files between a computer and a storage drive and across networked computers by comparing the modification times and sizes of files. [8] It is commonly found on Unix-like operating systems and is under the GPL-3.0-or-later license. [4][5][9][10][11][12]
sync is a standard system call in the Unix operating system, which commits all data from the kernel filesystem buffers to non-volatile storage, i.e., data which has been scheduled for writing via low-level I/O system calls. Higher-level I/O layers such as stdio may maintain separate buffers of their own. As a function in C, the sync() call is ...
Unix time[a] is a date and time representation widely used in computing. It measures time by the number of non- leap seconds that have elapsed since 00:00:00 UTC on 1 January 1970, the Unix epoch. In modern computing, values are sometimes stored with higher granularity, such as microseconds or nanoseconds.
