Functions
The block [Mode][opts::Mode] treats the input as a sequence of newline or
end-of-file terminated variable length records independent of input and
output block boundaries. Any trailing newline char- acter is discarded.
Each input record is converted to a fixed length output record where the
length is specified by the cbs operand. Input records shorter than the
conversion record size are padded with spaces. Input records longer than
the conver- sion record size are truncated. The number of truncated input
records, if any, are reported to the standard error output at the completion
of the copy.

The unblock [Mode][opts::Mode] treats the input as a sequence of fixed
length records independent of input and output block boundaries. The
length of the input records is specified by the cbs op-
erand. Any trailing space characters are discarded and
a newline character is appended.
