I would like to verify how much users have swap on their system by one-liner. Is there anything about the thing in Matlab prompt?
OS: Debian 8.5 64 bit Linux kernel: 4.6 of backports Hardware: Asus Zenbook UX303UA

No, this cannot be done in one line. Figuring out how much swap you have available requires detecting which OS-X version you are running. Current versions of OS-X would require asking the system for sysctl vm.swapfileprefix , removing the filename portion, resolving that directory to a device, and asking for the amount of free space on the device, together with totaling the size of all existing files that match the pattern starting with sysctl vm.swapfileprefix . Remember when you ask for the amount of free space on the partition to multiply by the blocksize to get bytes, because the file sizes will be in bytes.
