NAME

bcopy − interactive block copy

SYNOPSIS

/etc/bcopy

DESCRIPTION

Bcopy dates from a time when neither the UNIX file system nor disk drives were as reliable as they are now.  Bcopy copies from and to files starting at arbitrary block (512-byte) boundaries. 

The following questions are asked:

to: (you name the file or device to be copied to). 

offset: (you provide the starting “to” block number). 

from: (you name the file or device to be copied from). 

offset: (you provide the starting “from” block number). 

count: (you reply with the number of blocks to be copied). 

After count is exhausted, the from question is repeated (giving you a chance to concatenate blocks at the to+offset+count location).  If you answer from with a carriage return, everything starts over. 

Two consecutive carriage returns terminate bcopy.
