Halt command, Linux

From RZWiki

A command line program available on Linux platforms, including F5 BigIP; used to halt the device the command is executed on.

Usage Syntax

noinclude/noinclude

halt

Common options include:

• -f - force halt rather than calling shutdown with appropriate options passed
• -q - quite mode; only display errors

Usage Notes

Unless used with the -f option, this command simply calls the shutdown program

Using the shutdown command directly is preferable as it offers more options and flexibility

To reload or shutdown F5 BigIP LTM services only, use the bigstart command

Linux Usage Notes

With most Linux or Unix commands;

• Non root users may need to prefix commands with the sudo command, for example: sudo chmod 644 *
• Brief help can be displayed using the -h or --help parameter, for example: chmod --help
• A full command manual can be displayed using the man command followed by the command name, for example: man chmod
• Sometimes 'info' pages are used instead of or to provide more information than man pages; for example: info chmod
• Version information can normally be display using the -v, -V or --version parameter, for example: chmod --version. However, this paramater is also frequently used to display verbose output.

You could use the reboot and poweroff commands to perform the related functions their names imply but again, using the shutdown command is probably preferable.
