CRFILE(1) CRFILE(1)

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).
