用bash计算一天中发生多少次？,bash,shell,Bash,Shell,我有一个脚本，可以在internet断开连接时自动连接调制解调器，并在断开连接时写入日志，我的脚本如下所示： #!/bin/bash DATE=`date +%d-%m-%Y_%H:%M:%S` echo -n $DATE >> /www/restart.log echo ' Internet terkoneksi ke server OpenVPN' >> /www/restart.log sleep 20 while [ true ] do if tail -

脚本在重新连接internet后终止（我有原因，请不要问我为什么），并在internet启动时再次运行。日志如下所示：

#!/bin/bash
DATE=`date +%d-%m-%Y_%H:%M:%S`
echo -n $DATE >> /www/restart.log
echo ' Internet terkoneksi ke server OpenVPN' >> /www/restart.log
sleep 20
while [ true ]
do
    if tail -1 /www/vpn.log | grep 'Initialization Sequence Completed'
    then
        sleep 5
    else

我想计算一天内发生的重新连接次数，我希望日志文件如下所示：

#!/bin/bash
DATE=`date +%d-%m-%Y_%H:%M:%S`
echo -n $DATE >> /www/restart.log
echo ' Internet terkoneksi ke server OpenVPN' >> /www/restart.log
sleep 20
while [ true ]
do
    if tail -1 /www/vpn.log | grep 'Initialization Sequence Completed'
    then
        sleep 5
    else
        profile start > /dev/null 2>&1 &
        DATE=`date +%d-%m-%Y_%H:%M:%S`
        echo -n $DATE >> /www/restart.log
        echo ' Openvpn Disconnected. Koneksi internet direstart' >> /www/restart.log
        echo '---------------------------------------------------------------------------------------------------'      >> /www/restart.log
        rm /www/vpn.log
        break
    fi
done

可能吗？请注意，我的脚本在重新连接调制解调器后被终止，并在internet启动时再次调用。我不希望我的脚本每天24小时运行。

保持日志文件干净，并创建一个单独的日志分析器脚本来计算每天的连接数会更有意义

cut -s -d_ -f1 reconnect.log | uniq -c

在现有日志文件上添加任何内容之前，请使用

grep

和

wc

。了解这些工具，了解如何根据日期进行过滤。

而[true]

恰好是出于巧合的原因才起作用的，但它并不像您想象的那样起作用。你的意思可能是

，而true则是。。。哦，又是这样。很抱歉，你在这件事上是个傻瓜，如果你对我的帖子感到不安，就不要回答。^^当有人试图纠正你时，通常是为了帮助你学习。不要因此而生气顺便说一下，while[true]
和while[false]
在这里都会给出相同的结果<代码>为true时
和为false时
结果会有所不同。别担心，我没有生气。对不起我的语言。
