磁盘空间监控

   俺的这个磁盘空间监控，大量使用了awk，嘿嘿，enjoy it！

 

 

#!/bin/sh
#disk_monitor.sh

# out something like this:
# PARTITION_USED_MAX=/home
# PARTITION_USED_MAX_PER=78
# INODE_USED_MAX=/usr
# INODE_USED_MAX_PER=18
# of course , scan this definition twice

#USED=$(df -k | awk -F"[ ]*|%" '(NR>1){print $5}' | sort -nr | head -1)

#INODE_USED=$(df -i | awk -F"[ ]*|%" '(NR>1){print $5}' | sort -nr | head -1)
