Hello guys. Recently I had set up the trafic monitoring usign ipfw. But ofter hour or two it stopped working.. So after some testing I have found a bug, I think Since all this works only with Under FreeBSD 4.10 and udner debian. udner FreeBSD 5.2 and 5.3 I get errors, look : ------------ beggining ---------- #!/bin/bash test="240 \ 0 \ 240 \ 24535109 \ 448241787 \ 13385750 \ 30655883 \ 2428572717 \ 30495271 \ 29813961 \ 4850059 \ 240 \ 11804353 \ 58339445 \ 240 \ 240 \ 2280965" size=0 for i in $test; do size=`expr $size + $i` done echo "value 1" echo "$size" echo " " size=0 for i in $test; do size=$(( $size + $i )) done echo "value 2" echo $size ---------- end of script ---------- I get these results under different machines : Under FreeBSD 4.10-STABLE ./test value 1 3082976500 value 2 3082976500 Under FreeBSD 5.3 STABLE: ./test expr: illegal option -- 1 usage: expr [-e] expression expr: syntax error expr: syntax error expr: syntax error expr: syntax error expr: syntax error expr: syntax error expr: syntax error expr: syntax error value 1 value 2 3082976500 FreeBSD 5.2.1-RELEASE: ./test expr: illegal option -- 1 usage: expr [-e] expression expr: syntax error expr: syntax error expr: syntax error expr: syntax error expr: syntax error expr: syntax error expr: syntax error expr: syntax error value 1 value 2 3082976500 Debian with Kernel 2.4 value 1 3082976500 value 2 3082976500 I'm not C++ programmer so I can't look into .c files ...
