From d1880979032a8fb94917b517057770b1592e3c2c Mon Sep 17 00:00:00 2001 From: jkh Date: Fri, 18 Aug 1995 11:41:32 +0000 Subject: Add the cdcontrol program by Serge Vakulenko. It's my understanding that this is a superset of cdplay, and perhaps it's time to send cdplay into the bit bucket if this works well. According to the docs, it has a friendlier command structure, command line interface etc. Submitted by: Serge Vakulenko --- usr.sbin/cdcontrol/Makefile | 4 + usr.sbin/cdcontrol/cdcontrol.1 | 144 ++++++++++ usr.sbin/cdcontrol/cdcontrol.c | 622 +++++++++++++++++++++++++++++++++++++++++ 3 files changed, 770 insertions(+) create mode 100644 usr.sbin/cdcontrol/Makefile create mode 100644 usr.sbin/cdcontrol/cdcontrol.1 create mode 100644 usr.sbin/cdcontrol/cdcontrol.c (limited to 'usr.sbin/cdcontrol') diff --git a/usr.sbin/cdcontrol/Makefile b/usr.sbin/cdcontrol/Makefile new file mode 100644 index 0000000..86a42eb --- /dev/null +++ b/usr.sbin/cdcontrol/Makefile @@ -0,0 +1,4 @@ +PROG= cdcontrol +CFLAGS+= -Wall + +.include diff --git a/usr.sbin/cdcontrol/cdcontrol.1 b/usr.sbin/cdcontrol/cdcontrol.1 new file mode 100644 index 0000000..095c170 --- /dev/null +++ b/usr.sbin/cdcontrol/cdcontrol.1 @@ -0,0 +1,144 @@ +.Dd July 3, 1995 +.Dt CDCONTROL 1 +.Os FreeBSD +.Sh NAME +.Nm cdcontrol +.Nd compact disc control utility +.Sh SYNOPSIS +.Nm cdcontrol +.Op Fl s +.Op Fl v +.Op Fl f Ar discname +.Op Ar command args... +.Sh DESCRIPTION +.Nm cdcontrol +is a program to control audio features of a CD drive.
