#!/bin/bash

# Reading Manthan Status
echo "Manthan cat started"
cat /var/www/symmetric-ds-3.1.6/bin/my_mon.txt | while read LINE

do
    echo "Inside my loop"
    echo "$LINE"
    if [ "$LINE" == "false" ]; then
        echo "startedif_my"
        sudo lsof -n -i:8082 | grep LISTEN | awk '{ print $2 }' | uniq |sudo  xargs kill -9;
        sleep 30;
        sudo sh /var/www/symmetric-ds-3.1.6/bin/sym --port 8082 --server;
        break
    fi
done


#Reading Panel Status
echo "Panel cat started"
cat /var/www/symmetric-ds-3.1.6/bin/panel_mon.txt | while read LINE

do
    echo "Inside panel loop"
    echo "$LINE"
    if [ "$LINE" == "false" ]; then

        sudo lsof -n -i:8082 | grep LISTEN | awk '{ print $2 }' | uniq |sudo  xargs kill -9;
        sleep 30;
        sudo sh /var/www/symmetric-ds-3.1.6/bin/sym --port 8082 --server;
        break
    fi
done
echo "end of script"

当我运行上面的脚本时，脚本会读取第一个文件并回显$ Line。之后，它不会读取第二个文件，它只会持续作为脚本结束的回声。

你能告诉我为什么吗？

Answer 1

value=$(</var/www/symmetric-ds-3.1.6/bin/my_mon.txt)
if [ "$LINE" == "false" ]; then
echo"Inside loop"
fi

这对我有用。我猜是罪魁祸首

shell脚本使用cat读取文件
