How to make an xxxx bytes file
 

well i just wanted to know how do i make an xxxx mb file, it can be any junk.

supposr i want to make a file "test" which is 10 Mb. i dont care what the contents are. so how do i make it in one go.

one rather crude way is find a 10Mb file and rename it test.

try

dd if=/dev/zero of=test bs=1M count=10

man dd !

oops! i should've remembered reading this
