Shell脚步从文件中读取数据并赋值到命令行中执行

前提：本次需要测试性能测试，需要每次手动改动参数进行测试并获取执行结果，但是手动执行太繁琐，故编写shell循环执行。

java com.cipherxxx.crypto.pertest.SM4PerTest gcm 16 1 10000 #后面这几位都是参数：$ms $sz $ths $sloop

解决办法：写1个脚本执行后，执行结果在文件里，直接查看结果即可，以下是脚本。

一、数据列表：demo.txt

{"moshi":"ecb","size":"16","threads":"1","loop":"6000000"} {"moshi":"ecb","size":"16","threads":"4","loop":"6000000"} {"moshi":"ecb","size":"16","threads":"8","loop":"3000000"} {"moshi":"ecb","size":"16","threads":"16","loop":"1600000"} {"moshi":"ecb","size":"16","threads":"32","loop":"700000"}

二、demo.sh脚本

#!/bin/bash while read line do echo $line>line.txt #echo $moshi moshi=$(cat line.txt | sed 's/,/\n/g' | grep "moshi" | sed 's/:/\n/g' | sed '1d' | sed 's/}//g') ms=$(echo $moshi | tr -d '"') #echo $size size=$(cat line.txt | sed 's/,/\n/g' | grep "size" | sed 's/:/\n/g' | sed '1d' | sed 's/}//g') sz=$(echo $size | tr -d '"') #echo $ths threads=$(cat line.txt | sed 's/,/\n/g' | grep "threads" | sed 's/:/\n/g' | sed '1d' | sed 's/}//g') ths=$(echo $threads | tr -d '"') #echo $sloop loop=$(cat line.txt | sed 's/,/\n/g' | grep "loop" | sed 's/:/\n/g' | sed '1d' | sed 's/}//g') sloop=$(echo $loop | tr -d '"') #java com.cipherxxx.crypto.pertest.SM4PerTest gcm 1048576 32 100 echo "java com.cipherxxx.crypto.pertest.SM4PerTest $ms $sz $ths $sloop" >> result.txt echo "moshi: $ms,size: $sz,threads:$ths, sloop: $sloop" >> result.txt java com.cipherxxx.crypto.pertest.SM4PerTest $ms $sz $ths $sloop>> result.txt echo "===============================================">>result.txt done<demo.txt #从demo.txt获取文件
