comment Filesystem full: how to find the biggest directories or biggest file?
You must indicate to sort which column you want to sort by, and that it's numeric (not alphanumeric). That's what -k1,1rn would do. By default sort does uses alphanumeric sort on first column.

comment Replace filename with filepath with sed
Neat! Which version of bash does it need to work? dirname is old and standard enough that it will work just about anywhere.

comment Should I disable hyperthreading?
What type of CPU are you running on? Old P4's hyperthreading was rather bad, but the new stuff on i7 and newer is actually pretty good.

comment USB boot and newer BIOS and firmware
Yes, it is not a very memory efficient method, it's not something you want to run from (unless you got gobs of memory and don't care). The more normal PXE booting methods usually release the downloaded images upon executing them. Linux kernel's bzImage/initrd combos also release memory of the image after executing. Probably the best way would be to load a SquashFS image into ram, and use that as your rootfs as the OS is aware of 'this stuff is running in RAM anyway, no need to cache or load into memory' problems.

comment USB boot and newer BIOS and firmware
@tombull89, memdisk is what you're looking for. Bootloader loads memdisk, memdisk loads the entire ISO into memory, and then it transfers execution to the code on the ISO. And from that moment on it's like booting from any normal ISO. Take a look at ultimatebootcd.com/customize.html under the 'Adding ISO images' section for the configuration.

comment SysRescueCD on USB flash drive
Which BIOS/board is it? How old? Is USB booting enabled, and in right order for booting? Some boards give you different emulation modes for USB storage devices, might want to experiment with these.

comment How do I compare binary files in Linux?
DHEX is awesome is comparing binaries is what you want to do. Feed it two files and it takes you right to a comparative view, highlighting to differences, with easy ability to move to the next difference. Also it's able to work with large terminals, which is very useful on widescreen monitors.
