Question

如果可执行文件输出某个字符串，如何使用sh脚本进行测试？我使用./program运行可执行文件，并将其打印到控制台hello或goodbye。我想运行1000次并计算每个输出出现的次数。

#!/bin/sh
count=0
secs=60                        # Set interval (duration) in seconds.
endTime=$(( $(date +%s) + secs )) # Calculate end time.

while [ $(date +%s) -lt $endTime ]; do  # Loop until interval has elapsed.
    if [[ ./program = *hello* ]]; then
        count++
    fi
done

编辑（根据给出的答案部分修复）：

#!/bin/sh


winCount=0
totalCount=0
secs=60                        # Set interval (duration) in seconds.
endTime=$(( $(date +%s) + secs )) # Calculate end time.

while [ $(date +%s) -lt $endTime ]; do  # Loop until interval has elapsed.
        totalCount++
        case $(./program) in
                *\[1\]\ \[1\]\ \[1\]* )((winCount++)) ;;
        esac
done
echo "wins=$winCount"
echo "total=$totalCount"

尝试

#!/bin/bash runCount=0 secs=60 # Set interval (duration) in seconds. endTime=$(( $(date +%s) + secs )) # Calculate end time. while [ $(date +%s) -lt $endTime ]; do # Loop until interval has elapsed. # bash/ksh only ((runCount++)) runCount=$(expr $runCount + 1 ) case $(./program) in *\[1\]\ \[1\] ) ((matchCnt++)) ;; esac done echo "avg=$(( runCount / matchCnt ))"

你非常接近。为什么不使用未经认可的case语句，即。

#!/bin/sh count=0 secs=60 # Set interval (duration) in seconds. endTime=$(( $(date +%s) + secs )) # Calculate end time. while [ $(date +%s) -lt $endTime ]; do # Loop until interval has elapsed. case $(./program) in *hello* )((helloCnt++)) ;; *goodbye* ) ((goodbyeCnt++)) ;; esac done echo "hellos=$helloCnt goodByes=$goodbyCnt"

我想不出./program的简单替代品，所以我无法测试它。

如果您收到错误消息，请与我们联系。

此外，如果你的目标是尽可能快地运行它，那么使用循环计数器将消除对$(date +%s)驱动循环的相对昂贵的调用。即。

for (i=0;i<1000;i++) ; do case $(./program) in ... esac done

sh可执行if else语句
