[FreeNX-kNX] nxserver patch: fixes "egrep -q" and "ls --time-style"

[Rongsheng Fang]

Hi,

Enclosed is the patch for `nxserver' against the svn rev 204. It fixes 
the following command options:

1) "egrep -q": option `-q' is not supported on Solaris.

2) "ls --time-style": not supported by `ls' on solaris.

3) "echo -e": replaced with `printf' to make the output aligned with the 
header better.

The patch was generated by "$ svn diff -r 204 nxserver".

`mktemp' command isn't supported (natively) on Solaris until Solaris 10. 
I am thinking if we can use the following code to make it more portable?
Open for discussion.

====================================================================
if which mktemp >/dev/null 2>&1;
then
	tmp_file=$(mktemp "/tmp/.nxtmp_file.XXXXXXXXX")
else
	tmp_file="/tmp/.nxtmp_file.$(($RANDOM*$RANDOM))"
	touch $tmp_file && chmod 600 $tmp_file
fi
====================================================================
