[solved]-Using Ubuntu Script Use Bin Bash Current Df Grep Awk Print 5 Sed S G Threshold 1 Current G Q39009357

Using Ubuntu, this is the script to use:

#!/bin/bash

CURRENT=$(df / | grep / | awk ‘{ print $5}’ | sed ‘s/%//g’)

THRESHOLD=”$1”

if [ “$CURRENT” -gt “$THRESHOLD” ] ; then

echo “WARNING-Root partition space low Used:$CURRENT%“ >> ~/systemlog

Using an editor enter the script and name it script1

Make script1 an executable file:

$ chmod +x /~/script1

Now run script1 by passing in a 90, representing 90%, as theparameter.

$ cd ~

$ ./script1 90

Test to make sure your if statement works properly by passing ina 10 as the parameter.

$ ./script2

$ ./script1 10

$ ./script2

$ cat /~/systemlog

Now that you are becoming familiar with bash scripting enhancescript 1 to do these items:

Require the script to now use (2) parameters that are passedin.
Check for the number of parameters passed in and if it is not2, display an error message and exit.
The second parameter will represent a value for the minimumamount of available memory (IE: 200000).
Parse the output from the vmstat or free command for the amountof free memory. Let’s call this the free_value. Compare free_valueto the value passed in for parameter 2. If free_value is less thanparameter 2 issue a warning message that will be written to~/systemlog.

Test to make sure your script3 works properly by passing thesetest case parameters:

$ ./script3

$ ./script3 10

$ ./script3 10 800000

$ ./script3 90 200000

$ ./script3 90 800000

$ cat /~/systemlog

I need the script with the parameters and below. I have script1working, it’s just the last half that I don’t have.
