linux时间和定时脚本

1. 有时候希望脚本可以定时执行， Linux有这种机制

# cd /etc/cron.d

# cat sysstat

# Run system activity accounting tool every 10 minutes
*/10 * * * * root /usr/lib64/sa/sa1 -S DISK 1 1
# 0 * * * * root /usr/lib64/sa/sa1 -S DISK 600 6 &
# Generate a daily summary of process accounting at 23:53
53 23 * * * root /usr/lib64/sa/sa2 -A
