Date: Fri, 1 Jun 2001 15:44:51 -0500 From: "Jacques A. Vidrine" <n@nectar.com> To: freebsd-mobile@freebsd.org Subject: `pccardc status' patch Message-ID: <20010601154451.C701@shade.nectar.com>
next in thread | raw e-mail | index | archive | help
I found this functionality useful for certain scripts. ISTR something
similar in PAO once upon a time.
$ pccardc status
slot 0: filled
slot 1: empty
$ pccardc status 0
slot 0: filled
$ pccardc status 9 || echo exit_status=$?
pccardc: /dev/card9: No such file or directory
exit_status=1
The patch is against 4.3-RELEASE.
Cheers,
