I recently came across this awesome list, which lists all the command line tools, that are deprecated (or let's say whose functionality can be replicated) by the new ip tool.

Recently trying to get accustomed to systemd, I learned that almost all functionality of cron can be replicated by systemd. What are other tools whose functionality can be replicated by systemd?

The obvious ones - these are what systemctl replaces:

  • service
  • chkconfig on redhat and update-rc.d on debian, if a systemd unit has been written for the service.
  • reboot, poweroff, halt, telinit.
  • pm-suspend and friends have apparently gone away. As a cross-distro effort it's the sort of thing that systemd aims to accomplish; it's just interesting given the hooks and quirks that pm-utils supported, and I'm not aware of any fallout from systemd replacing it.

Also systemd-analyze provides a similar function to bootchart.

As pointed out by others, it probably makes more sense to enumerate the files provided by systemd, or the documentation. By doing so, I noticed one more obscure command, runlevel.

systemd only emulates runlevels, so runlevel is another of the legacy commands. Searching for an equivalent command turned up systemctl list-units --type target (note list-units only shows active units unless directed otherwise). The output is not as obvious, because targets tend to depend on other targets, and you can have multiple targets active at once, independent or overlapping.

However for now I can't think exactly when you would use the runlevel command. I have an impression it would be used interactively as a summary of the state of the init system. In which case, the better alternative would be systemctl status.

  • Debian and co's service command stops associated sockets when stopping services, so I still stick to it instead of systemctl.

You could browse the man pages that systemd comes with. On my fedora 22 I see

$ rpm -ql systemd | grep -c man1
$ rpm -ql systemd | grep -c man8

32 man pages for commands like localectl, and 111 pages on features like systemd-timedated. Alternatively, look through apropos systemd.

  • Nice. I note this also shows e.g. the manpage for reboot, a command which systemd provides for compatibility but which it describes as "legacy only".
