Creating specific sized file

To create a specific sized file, dd command can be used. Example below will create a file named output with 10M size:

$ dd if=/dev/zero of=output bs=1M count=10
where bs is block size, and count is number of blocks to be created

The output:

$ ls -lh output
-rw-r--r-- 1 user user 10M 2009-11-14 06:21 output
