Thank you very much ;) Maybe i must use XSLT with 0.99 kernel, or what? I'm talking about patch posted here: Message-ID: <[EMAIL PROTECTED]> Archived-At: <http://permalink.gmane.org/gmane.linux.kernel/485999> ,-*- diff snip -*- |- t4=`echo $t3 | gawk '{ print $1 }'` |- t5=`echo $t1 | gawk '{ print $1 }'` |+ t4=`pos_param 1 $t3` |+ t5=`pos_param 1 $t1` 5 t6=`echo $t4 - $t5 | tr a-f A-F` 6 t7=`( echo ibase=16 ; echo $t6 ) | bc` `-*- I've just noticed, that things on lines 5 and 6 may be optimized. t7=`printf "%lu" $(( 0x$t4 - 0x$t5 ))` No tr, no bc, no pipes -- magic! Better know and use our *fine shell*. And if you jouined us, Tim, maybe can share your experience and test patch above and this one, please? Message-ID: <[EMAIL PROTECTED]> Archived-At: <http://permalink.gmane.org/gmane.linux.kernel/485984> It's just my optimization hint. I have no bc, and i'm sure things, like that will cause silent misinformation. Anyway, what is so bad in `sh'? Thanks. -*- OT -*- > info '(bc)About Expressions and Special Variables' GFDL.
