Some useful Commands in Solaris 10

if you ever needed to create an empty file with certain size, then all you have to do is to use this command:

dd if=/dev/zero of=FILE_NAME bs=BLOCK_SIZE count=NUMBER_OF_BLOCKS

where FILE_NAME is the name of target file and NUMBER_OF_BLOCKS is number of blocks per file, the size of the file is going to be created based on this formula:

File size = NUMBER_OF_BLOCKS x BLOCK_SIZE

as an example:

dd if=/dev/zero of=test_for_download bs=1024 count=1048576
