Subject: kill: deprecat invocation as 'pid' command name
X-Git-Tag: v2.25-rc1~329^2~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c5b057b3422504a671ee588fa66574ae876521f1;p=thirdparty%2Futil-linux.git

kill: deprecat invocation as 'pid' command name

Enabling options by renaming command is both unexpected and undocumented.
This magic is now deprecated and with remark of removal of this
functionality in future.
