我有这个脚本:
FINISH=0;
trap 'FINISH=1' SIGINT
INTERVAL=100;
while true
do
START=`date +%s`;
php-cgi -f process.php;
STOP=`date +%s`;
ELAPSED=$(($STOP-$START));
SLEEP=$(($INTERVAL-$ELAPSED));
if [ $SLEEP -gt 0 ]
then
echo "sleeping for $SLEEP seconds";
sleep $SLEEP;
fi
if [ $FINISH -eq 1 ]
then
echo "exit";
break;
fi
done
但它不能像我想的那样工作 - 我希望它只设置FINISH = 1但它会杀死当前执行的命令(php-cgi或sleep) - 如何避免这种情况?其实我不希望它杀死php-cgi ...

这可能适合你。
#!/bin/bash
trap 'exit' SIGINT
interval=100;
while true
do
start=$(date +%s)
nohup php-cgi -f process.php
stop=$(date +%s)
((elapsed = stop - start))
((sleep = interval - elapsed))
if (( sleep > 0 ))
then
echo "sleeping for $sleep seconds"
sleep "$sleep"
fi
done
