Script to clean up logs under Linux

Requirement: Because/var partition separately, the size of the partition is 5G, the log is full, you need to write a script to clean up the log files regularly

#!/bin/bash

# #delete Log script, write by XL

Log_dir1=/var/log

Log_dir2=/var/spool/mail

Log_dir3=/var/spool/mqueue

Root_uid=0

# #Must is use as root to run this script

If ["$UID"-ne "$ROOT _uid"]

Then

echo "must is root to run this script."

Exit 1

Fi

CD $LOG _dir1 | | {

echo "Can not change to necessary dircectory." >&2

Exit 1

}

#把空设备重定向到文件里面

Cat/dev/null > Maillog && echo "Logs cleaned up."

Cat/dev/null > Maillog.1 && echo "Logs cleaned up."

Cat/dev/null > Maillog.2 && echo "Logs cleaned up."

CD $LOG _dir2 | | {

echo "Can not change to necessary dircectory." >&2

Exit 1

}

Cat/dev/null > Root && echo "Logs cleaned up."

Cat/dev/null > Stock && echo "Logs cleaned up."

# # #清除mqueue下的小文件

CD $LOG _dir3
