工作学习 / 专业技术讨论 / 贴个unix shell环境的小题目给大家玩玩儿。
输入变量为一不超过１０位的整数。要求输出值在输入值pad leading zero to make the length
to 10. 看看谁的办法最简洁。
要求：不用使用文件，可以使用管道（pipe).my solution is:
outvar=`echo $invar|sed -e 's/\(^.$\)/000000000\1/' -e 's/\(^..$\)/00000000\1/' -e 's/\(^...$\)/0000000\1/' -e 's/\(^....$\)/000000\1/' -e 's/\(^.....$\)/00000\1/' -e 's/\(^......$\)/0000\1/' -e 's/\(^.......$\)/000\1/' -e 's/\(^........$\)/00\1/' -e 's/\(^.........$\)/0\1/'`

太复杂。转成string后，前面加10个0，然后取右边10位就行了。
