Sorry to be continuing this thread, but I find a certain kind of elegance in bash which isn't actually there, but helps me sleep at night.
bash# iptoint(){ oct1=`echo $1|awk -F\. '{print $1}'`; oct2=`echo $1|awk -F\. '{print $2}'`; oct3=`echo $1|awk -F\. '{print $3}'`; oct4=`echo $1|awk -F\. '{print $4}'`; echo $[($oct1<<24)+($oct2<<16 )+($oct3<<8)+$oct4 ];} bash# inttoip(){ echo $[$1>>24].$[($1>>16)&255].$[($1>>8)&255].$[$1&255]; }
bash# inttoip 1089055123 64.233.169.147
BASH? Hahaha. Real Admins use sh. More portable(*). Simple: v=$1;for n in 4 3 2;do eval o$n=`expr $v % 256`;v=`expr $v / 256` done; echo $v.$o2.$o3.$o4 Needlessly complex (just to keep up sh's reputation for complexity): v4=$1;for n in 4 3 2;do eval o$n=`eval expr \\$v$n % 256`;eval v`expr $n - 1`=`eval expr \\$v$n / 256` done; echo $v1.$o2.$o3.$o4 $ ipscript 1089055123 64.233.169.147 $ (*) Not a claim of actual portability of this code. Just having fun writing UGLY shell code. ... JG -- Joe Greco - sol.net Network Services - Milwaukee, WI - http://www.sol.net "We call it the 'one bite at the apple' rule.
