A convenient block copy program. bcp
is intended to copy contiguous
chunks of files from point A to point B. Want to cookie-cutter a
piece out of of a file and plop it down in the middle of another file?
Here you go.
The main use case I want for myself is doing light surgery to disk images, such as "copy this bootloader block into the image at this offset".
``` $ bcp --help bcp 0.2.0 Simon Heath icefox@dreamquest.io A convenient program for copying blocks of bytes within files.
USAGE:
bcp [FLAGS] [OPTIONS]
FLAGS: -v, --verbose Verbose output, with progress bar. -h, --help Prints help information -V, --version Prints version information
OPTIONS:
-s, --src-offset src-offset
to
the end of the file. Asking to read past the end of the source file is an error.
ARGS:
Basically, the goal is to make a nicer version of the traditional Unix
utility dd
, because dd
is just... weird. See the Jargon file
entry for it, particularly
lines like "the user interface for it is clearly a prank" and "it has
no exact replacement". So, why not just make a replacement?
In particular: I want a Unix-y command line interface, I want to be
able to blit large chunks of files from point A to point B, and I
really don't need EBCDIC translation, byte swapping, "fail if the
output file already exists" being classified as a conversion, a
default block size of 512 bytes because that's how big hard drive
blocks were on a PDP-11, or the ability to have it catch a SIGUSR1
and print I/O statistics. I want it to copy bytes, and that's all.
...Okay, and have a progress bar. But that's it. Honest!
