See if there are any custom users (ordinary users) on your Linux system, and if so, how many are there?

[email protected] ~]# cat 6.sh

#/bin/bash

N= ' awk-f: ' $3>=500{print '/etc/passwd |wc-l '

If [$n-gt 0];then

echo "$n Common users"

Else

echo "No common users"

Fi

Write a shell script that detects all disk partition usage and inode usage and logs to a log file named after today's date, sending you an email notifying you when a partition capacity or Inode usage is greater than 85%.

#bin/bash
disk_usize= ' df-h |awk ' {print $ ' |sed s#%# #g '
inode_usize= ' df-i |awk ' {print $ ' |sed s#%# #g '
date= ' DATE +%f '
Log=${date}.log
df-h > $LOG
df-i >> $LOG
For i in $DISK _usize $INODE _usize;
if [$i-ge]; Then
echo "Space more than 85%" |mail-s "warnning" 22222222@qq. com
Else
Echo OK
fi
Done
