View source for Btrunc

This truncates/extends a file to the specified length.
 btrunc <filename> <bytes>

== Examples ==
 ;Create a file of 15 bytes, (13 for the text plus 2 for [[$crlf]])
 [[write]] -c btrunc.test Hi I am Dana!
 [[echo]] -ag File size: [[$file]](btrunc.test).size
 
 ;Lets cut it down to only two bytes.
 btrunc btrunc.test 2
 echo -ag File size after btrunc: $file(btrunc.test).size
 echo -ag File content: [[$read]](btrunc.test,1)
 
 ;Now lets make the file back to 15 bytes.
 btrunc btrunc.test 15
 echo -ag File size at end is now: $file(btrunc.test).size

== Note ==
This alias is very rarely used to extend files; usually used to truncate files only.
