From e9a910b33c7837b4b868e3abda18eb4810df7f02 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 4 Oct 2025 09:14:33 +0100 Subject: config/git: import suckless sbase i currently use the output of sha512sum in several places of xbmk, which is a bit unreliable in case output changes. other cases where i use util outputs in variables are probably reliable, because i'm using mostly posix utilities in those. to mitigate this, i now import suckless sbase, which has a reasonable sha512sum implementation. *every* binary it builds is being placed in build.list, because i'll probably start using more of them. for example, i may start modifying the "date" implementation, adding the GNU-specific options that i need as mentioned on init.sh i'm importing it in util/ because the sha512sum util is needed for verifying project sources, so if sbase itself is a "project source", that means we can into a chicken and egg bootstrapping problem. this is sbase at revision: 055cc1ae1b3a13c3d8f25af0a4a3316590efcd48 Signed-off-by: Leah Rowe --- util/sbase/whoami.c | 37 +++++++++++++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 util/sbase/whoami.c (limited to 'util/sbase/whoami.c') diff --git a/util/sbase/whoami.c b/util/sbase/whoami.c new file mode 100644 index 00000000..c991ac29 --- /dev/null +++ b/util/sbase/whoami.c @@ -0,0 +1,37 @@ +/* See LICENSE file for copyright and license details. */ +#include +#include +#include +#include + +#include "util.h" + +static void +usage(void) +{ + eprintf("usage: %s\n", argv0); +} + +int +main(int argc, char *argv[]) +{ + uid_t uid; + struct passwd *pw; + + argv0 = *argv, argv0 ?
