I'm trying to write a script that reads out a file and takes each numbered line and divides by 256. the freemem file is from my vmstat outout's from a cronjob running. there's a lot of line's so i figured this would be easier but I'm drawing a blank on creating the script to read each line and divide by 256.
Here is the basic's of the script so far:
This works but I can't figure out what I need to do to get the / 256 to work and output it to another file.
Any help would be greatly appriciated!
Also the freemem file looks like this:
Really not a big deal but if you know how I can exclude the (mem, faults, script and time) would be really great but not important.
