NAME¶

crfile - Create arbitrary sized files

SYNOPSIS¶

crfile -f filename -s size [-w[len] | -n]

DESCRIPTION¶

crfile is used to create a file of the specified size, filled with random ASCII characters. The -n switch allows the creation of files padded with null characters (ie. containing large 'holes') that have an apparent length of the specified size, but contain only one random character.

OPTIONS¶

-f filename

specifies the file to be created. If the file exists, an error is generated.

-s size

size is the size of the file, in bytes

-wlen

wrap each line of output at len characters. If len omitted, wrap at 80 characters.

-n

Pad the file with null characters instead of random ASCII text. This allows for the rapid creation of large files (useful for verifying that programs can deal with files > 2GB in size, for example).
