It is known as the command line interface (CLI). You can check memory usage (in percentage) of all the process running on your Linux operating system with the following command: $ ps -o pid,user, % mem, command ax | sort -b -k3 -r As you can see, all the processes with memory usage in percentage is listed in descending order (The processes using most of the memory is listed first). Linux RAM is composed of chunks of memory called pages. If there's no graphic interface, you may have to manually mount your usb drive (unless your OS happens to auto-mount drives). Consider using kgdb insetad of dumping memory. A lower setting of 128M is always better because if PHP scripts are trying to use more than 128M, those scripts would now return memory limit exceeded errors. Please cite: Langmead B, et al. On Linux machines, you can use the wonderful proc filesystem and look at the meminfo "file". It allocate memory dynamically and by allowing less-used pages to be moved onto swap space. Wait a minute… that sounds difficult.
