1.for循环以及加法的使用
portStr=`lsof -i:56801 | head -2`
count=0
for str in `lsof -i:56801 | head -2`
do
((count=count+1))
echo "Count: $count"
if [ $count == 11 ]; then
echo "Find Just Rigth Port ($count): $str"
else
echo "print string ($count): $str"
fi
done
对于加法,搜了一下,本文中采用的是比较人性化的方式,其他方式总结如下:
let "n = $n + 1";: $((n = $n + 1));: $[ n = $n +1 ];n=$[ $n + 1 ];let "n++";(( n++ ));: $[ n++ ];
