Furthermore, we will provide info on several shutdown options. Also, special shutdown scripts are used for the automation of routines that are at times relatively easy to prepare.īelow, we will show you where one enters CMD commands and the specific syntax that one must observe. This means that geographically-remote PC and servers are remotely time-controlled via manual command entries. Due to their adaptability, shutdown routines play an important role in the administrative field. Each mode is intended for a specific use case. A fine adjustment of the desired mode occurs through the addition of further control parameters. ![]() One can select from various shutdown options and as a result proceed in a number of various ways. Other advantages include flexibility and adaptability. Should one issue a shutdown command, the computer can be shut down directly and quickly. ![]() Detours across the Windows user interface are avoided. The advantages of command-based control are obvious: through Windows shutdown commands, you save yourself mouse clicks and don’t have to surf through menus. For shutting down your computer, another program addresses the command line tool: the “ shutdown.exe”, for example, shuts off the computer immediately after the program is called up, restarts it or logs off the current user. Behind the designation there is ultimately an executable program: the cmd.exe, which provides a line for the command input (the actual prompt). ahhh oh well.The Windows command prompt is a powerful tool from the old days of MS-DOS which today still accepts countless commands for special purposes. Which is somewhat pointless when the +m parameter is easier to type. sudo shutdown -h `date -date "now + 10 minutes" "+%H:%M"` If you're not sure, wait 5 minutes before forcing the restart or shutdown. Thanks for pointing that out My mistake you're right.īut you can still do it but it seems maybe to the nearest minute. Once your Mac is off, wait for 30 seconds to give all devices time to spin. Something like: shutdown -h `date -date "now + 60 seconds"`ĮDIT: The above no longer works on more recent builds of Ubuntu. If you wanted to do it in seconds or hours or something very specific you could do In that case, the command syntax is: sudo shutdown +m. Alternatively, use the relative format ( +m) and schedule a shutdown in a defined number of minutes from the time you run the command. For example, to require a shutdown at 7 AM in the morning, the command is: sudo shutdown 07:00. ![]() Minutes and the second at the absolute time specified.Īs pointed out, the command sudo shutdown -h +1 The command follows the syntax: sudo shutdown hh:mm. If the problem persists and is not resolved with the reinstall of your software, it may be a recurring issue with corrupt software. Shutting Down a Mac via Terminal with ‘halt’ The ‘halt’ command can also instantly shut down a Mac via the command line.

By default, MacBook Air and Pro automatically go into sleep mode after 2 minutes of inactivity while on battery power. Where the year, month, and day may be defaulted to the current May be the word now (indicating an immediate shutdown) or specifyĪ future time in one of two formats: +number, or yymmddhhmm, Using the basic calls, I don't see a way to do it with seconds, but it looks like you can do it with minutes: time Time is the time at which shutdown will bring the system down and You can also reboot by using -r instead of -h.Īs you mentioned in your comment, you can add a delay programmatically, then shut down the system immediately withīut note that that command will require root access. In OS X you can shutdown in one minute using the following command:ĪFAIK, it's not possible to specify seconds instead of minutes with this command.
