From 273c10fc2c508715f8810eb640d6561bf0caaabf Mon Sep 17 00:00:00 2001 From: James Youngman Date: Mon, 4 Aug 2008 18:51:21 +0100 Subject: Document uptime. * doc/coreutils.texi (uptime invocation): document uptime. * TODO: uptime is documented now. * src/uptime.c (print_uptime): Use fprintftime to print the time, rather than printf. This should make the situation better for translations. --- doc/coreutils.texi | 38 +++++++++++++++++++++++++++++++++++--- 1 file changed, 35 insertions(+), 3 deletions(-) (limited to 'doc') diff --git a/doc/coreutils.texi b/doc/coreutils.texi index b47448f5d..f60f9c7fb 100644 --- a/doc/coreutils.texi +++ b/doc/coreutils.texi @@ -31,7 +31,6 @@ @c FIXME: the following need documentation @c * [: (coreutils)[ invocation.
