How to resize root ext3 file system without LVM

My Debian vmware image has run out of space. I've expanded the disk image but now need to increase my root partition to see the additional space. My volume is setup as follows Disk /dev/sda: 50 GiB, 53687091200 bytes, 104857600 sectors Disk model: VMware Virtual S Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x37ce2932 Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 48236543 48234496 23G 83 Linux /dev/sda2 48238590 52426751 4188162 2G 5 Extended /dev/sda5 48238592 52426751 4188160 2G 82 Linux swap / Solaris I understand that in order to expand sda1, any new space has to be directly after it. All the examples I've read either a) use LVM or b) dont have an Extended sda2 partition directly after sda1. Can anyone point me to a reference that will show me how to expand sda1 in this scenario? I know I will have to switch off/remove swap on sda5, but what do I do about sda2?
