[LTP] [PATCH LTP] -Cpuhotplug06:Skip the test if "htop" is used.

[Siliang, Yu]

From: "Yu,Siliang" <siliangx.yu@intel.com>

In some distro, "htop" is used instead "top", which doesn't support '-b'. Skip the test if "htop" is used.

Hi,

> In some distro, "htop" is used instead "top", which doesn't support '-b'. Skip the test if "htop" is used.
Could you be more specific (which distro, ...)?
Do you mean binary is top and it's a symlink (or something) to htop?
Trying to detect '>' suggests you target to symlink and the command on linew 76 is top
top -b -d 00.10 > /dev/null 2>&1 &

But in that case it'd be better to parse 'top -v'.

[[ ]] is a bashism, please use [ ].
