shell 脚本中传递参数3种方法的比较

Bash里使用getopts解析非选项参数

By reading from a configuration file:

PINTOOL	obj-ia32/cacheSim3.so
mode 0
nL1	16
nL1Set	256
nBlockPerL1Set	1
nL2	1
nL2Set 16384
nBlockPerL2Set	16
nStoreBuffer	64	
emitTrace	0
coherenceMode	D
L1Latency	2
L2Latency	10
MemoryLatency	300

#!/bin/sh

if [ $# -lt 1 ]; then
	echo "Usage: $0 <configure>"
	exit
fi
