How to read from file and convert from string to integer?
Hi all,
I am trying to write a script to be able to
Run top command
Pick the PIDs that are taking more than 90% of CPU time
Get more details like what is the script name and location for that PID
Script should run until I manually kill it by ctrl + C
I have come up with following script for this:
But I think I am not doing data type conversion properly for $cpu at line
I think when I read from $filename cpu is coming as string and inside if condition, I am trying to use it as integer. This guess is from the fact that I keep getting error for the line if [ $cpu -ge 90 ]; then as below:
When I tried to put $cpu and 90 in double quotes or tried to use >= instead of -ge, I get a different error as below:
Can someone please suggest me how correct this error so my script can work.
I am using:
Thanks in advance.
