a.)all of your assignments like this are wasting CPU and memory by using cat when it is not needed. Try:

While I run the script it seems everything okay as usual the output of run script is,

Note, however, that if a mounted filesystem is ever unmounted or a new filesystem is mounted between runs of your script, there is no guarantee that the order of the percentage values stored in the arrays usep and usep1 are in the same order!

ip-monitor
IP-MONITOR(8) Linux IP-MONITOR(8)NAME
ip-monitor, rtmon - state monitoring
SYNOPSIS
ip [ ip-OPTIONS ] monitor [ all | OBJECT-LIST ] [ file FILENAME ]
DESCRIPTION
The ip utility can monitor the state of devices, addresses and routes continuously. This option has a slightly different format. Namely,
the monitor command is the first in the command line and then the object list follows:
ip monitor [ all | OBJECT-LIST ] [ file FILENAME ]
OBJECT-LIST is the list of object types that we want to monitor. It may contain link, address, route, mroute, prefix, neigh and netconf.
If no file argument is given, ip opens RTNETLINK, listens on it and dumps state changes in the format described in previous sections.
If the file option is given, the program does not listen on RTNETLINK, but opens the given file, and dumps its contents. The file should
contain RTNETLINK messages saved in binary format. Such a file can be generated with the rtmon utility. This utility has a command line
syntax similar to ip monitor. Ideally, rtmon should be started before the first network configuration command is issued. F.e. if you
insert:
rtmon file /var/log/rtmon.log
in a startup script, you will be able to view the full history later.
Nevertheless, it is possible to start rtmon at any time. It prepends the history with the state snapshot dumped at the moment of starting.
