• Shell编程之函数调用


    Shell中的函数调用的使用方法见我下面的代码示例:

    #!/bin/bash
    
    # value init
    
    ExP="adb shell /data/local/tmp/vpxdec  --yv12 --flipuv  -t 2 --md5   data/local/tmp/vp9Input/subset_function_test/Boating_1920x1080_t4_yv12_400frames_skip200.webm";
    TT="adb shell ls -l /data/local/tmp/";
    loop_count=2;
    targetMd5="2e8698fe47dd40bf6260206416530985";
    
    # Compare two value and output result,$1 is src,$2 is target
    function Compare()
    {
        #echo "Source value:$1, Target value:$2";
        if [ "$1" = "$2" ]; then
                echo "The same!";
            return 0;
        else
                echo "Different!"
            return 1;
        fi
        
    }
    
    # LoopEx: excute a programm in a loop, $1 is program,$2 is loop count, $3 is targetMd5
    function LoopEx()
    {
        local Ex=$1;
        local loop_count=$2;
        local target=$3;
        echo -e "Programm is $Ex 
    loop_count ==$loop_count, TargetMd5==$target"
        for i in $(seq $loop_count); do
            local output=$($Ex);
            local outputMd5=${output:0:32}
            Compare $outputMd5 $target;
            if [ "$?" != "0" ]; then
                echo "Loop Break index is [$i],result MD5:$outputMd5"
                break
            fi
        done;
    }
    
    # function main, shell excute from here
    function Main()
    {
        echo "Imagation GPU Version test run ...";
        LoopEx "$ExP" $loop_count $targetMd5
    }
    
    Main;

    后面写其他的简单脚本可以套用这个模板来做
