我需要每10分钟运行一次shell脚本。每次脚本运行时，我都会将输出附加到日志文件中。一旦日志文件的大小达到10 MB，我需要停止脚本运行。怎么能实现，请帮助!!

./test.sh >> log_file 

3 个解决方案

#1

maximumsize=10000 #KB

while :
do
    ./test.sh >> log_file
    actualsize=$(du -k log_file | cut -f 1)
    if [ $actualsize -gt $maximumsize ];then
        echo "logsize exceed.stop."
        break
    fi

    sleep 600
done

#2

You should modify your test script : put your process into a function, add your function into a loop, condition of the loop (size of your log file under 10MB) and at the end of the loop add a sleep 600 to wait for ten minutes

您应该修改您的测试脚本：将您的进程放入一个函数，将您的函数添加到循环中，循环的条件（日志文件的大小低于10MB）并在循环结束时添加一个休眠600等待十分钟

You might add to the start of your test.sh script a test, if the log file > 10MB then do not run (exit), or you could archive (maybe gzip -9 or xz -9) the log, if it's all text output then it should compress a LOT. Or you could pipe the script's output through gzip to compress it right away.

您可以在test.sh脚本的开头添加一个测试，如果日志文件> 10MB然后不运行（退出），或者您可以存档（可能是gzip -9或xz -9）日志，如果它是全文输出那么它应该压缩很多。或者你可以通过gzip管道脚本的输出来立即压缩它。

And also use cron/anacron to run the script regularly, like add */10 * * * * user test.sh to /etc/crontab...

并且还使用cron / anacron定期运行脚本，例如将* / 10 * * * * user test.sh添加到/ etc / crontab ...
