Btrunc
From Scriptwiki
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.
