[LTP] Why -f -l options of runalltests.sh are invalid on a arm-linux system?

[Stone C. <cre...@ho...>]

Hi,all
I am testing an arm-linux system whose commands collection is BusyBox. 
The -f -l options of runalltests.sh are invalid and I can only execute 
tests with pan following -f option to specify a commands_file and -l option 
to specify a result_log file.
Is it due to any program not in Busybox?
programs in /bin:
ash
busybox
cat
chgrp
chmod
chown
cp
cpio
date
dd
df
dmesg
echo
false
getopt
grep
gunzip
gzip
hostname
kill
ln
ls
mkdir
mknod
mktemp
more
mount
mv
nano-X
pidof
ping
ps
pwd
rm
rmdir
sed
sh
sleep
stty
sync
tar
touch
true
umount
uname
usleep
vi
zcat

/usr/bin is empty

Robert Jiang
