Subject: [PATCH] Confirm success for each tc -batch command
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If `tc -force -batch' is fed by a controlling program from a pipe,
it's not possible to recognize when a command has been processes
successfully.
This patch adds an optional `-OK' option to the tc(8) tool, so `tc
-force -OK -batch' will print "OK\n" to standard output on each
successfully completed tc command.
