Hints for usage of the -s, -f, -d, -n, and -o flags
One helpful feature of the rmss command, when used in this way, is that it can be terminated with the interrupt key (Ctrl + C by default) without destroying the report that has been written to the output file. In addition to writing the report to the output file, this causes the rmss command to reset the memory size to the physical memory size of the machine.
You can run the rmss command in the background, even
after you have logged out, by using the nohup command.
To do this, precede the rmss command by the nohup command,
and follow the entire command with an & (ampersand), as follows:
# nohup rmss -s 48 -f 8 -o foo.out foo &
