  • I run this via crontab every one minute on my machine occasionally to see if a process is eating up my system's resources.

  • While `echo rm * | batch` might seem to work, it might still raise the load of the system since `rm` will be _started_ when the load is low, but run for a long time. My proposed command executes a new `rm` execution once every minute when the load is small. Obviously, load could also be lower using `ionice`, but I still think this is a useful example for sequential batch jobs. Show Sample Output

  • Show the current load of the CPU as a percentage. Read the load from /proc/loadavg and convert it using sed: Strip everything after the first whitespace: sed -e 's/ .*//' Delete the decimal point: sed -e 's/\.//' Remove leading zeroes: sed -e 's/^0*//' Show Sample Output


    5
    sed -e 's/ .*//' -e 's/\.//' -e 's/^0*//' /proc/loadavg

  • helps you keep watch on the load of a system, without having to stare constantly at the terminal. The -d argument to watch highlights the difference from the last run, making it easier to note how the load is fluctuating. The sed command just strips off the information about how long the box has been up, and how many users are logged in. Show Sample Output


    2
    watch -n 7 -d 'uptime | sed s/.*users,//'
