Hey there,
today I tried to run a script on one of my busybox installations which
has been created by the famous “makeself” script.
It failed because the tty command did not support the “-s” option.
I wanted to quickly add that option to tty and found out, that it’s
already in there, but is only enabled in SUSv2 mode?
Here’s the code in coreutils/tty.c:
IF_INCLUDE_SUSv2(silent = getopt32(argv, "s");)
IF_INCLUDE_SUSv2(argv += optind;)
IF_NOT_INCLUDE_SUSv2(argv += 1;)
And here’s what I found when grepping through the whole busybox source
for IF_INCLUDE_SUSv2:
# grep -r IF_INCLUDE_SUSv2 *
coreutils/tty.c: IF_INCLUDE_SUSv2(int silent;) /* Note: No longer
relevant in SUSv3. */
coreutils/tty.c: IF_INCLUDE_SUSv2(silent = getopt32(argv, "s");)
coreutils/tty.c: IF_INCLUDE_SUSv2(argv += optind;)
coreutils/tty.c: IF_INCLUDE_SUSv2(if (!silent) puts(s);)
include/usage.h: IF_INCLUDE_SUSv2( "\n" \
include/autoconf.h:#define IF_INCLUDE_SUSv2(...)
include/usage.src.h: IF_INCLUDE_SUSv2( "\n" \
So, is it safe to assume that this needs to be cleaned up since it is
not used anywhere else?
bye and thanks,
Alex
