Linux lower root partition usage monitoring

A large number of log files are generated due to the usual server runtime. Every once in a while the root directory is packed, so write this script to monitor, when the space usage reaches 70% of the time to clean up the log, and add this code to the scheduled task, the code is as follows:

#!/bin/bashdf-h | grep sd > 1.txthead-1 1.txt | awk ' {print $ ' > 2.txtsed-i ' s#%# #g ' 2.txtsize= ' cat 2.txt ' #截取df命令的使用率的值if [$size-ge 70 ];thenrm-rf/var/log/messages-*cp/dev/null/var/log/messages << Jiangyjiang echo "It ' s ok!"  else echo "The size is too small,not to delete!" Fi
