# Broadcast Copy

Any easy way to copy files between terminals or computers on a local network.

Note: bcp currently assumes a trusted network, use with caution

# Compiling

make
or
gcc -D_FILE_OFFSET_BITS=64 -o bcp bcp.c

# Installation

```
$ make install
```

 One line install:
```
$ bash -c "mkdir /tmp/bcp && cd /tmp/bcp && curl -L# https://github.com/jgallen23/bcp/archive/master.tar.gz | tar zx --strip 1 && make install"
```

In OSX, you can use @gil's homebrew solution: https://github.com/gil/homebrew-bcp

# Alternatives:

* A great (more robust) program that uses polling: http://www.fefe.de/ncp/

* Another great approach, requires knowing name of sent file: https://www.udpcast.linux.lu/cmdlinedoc.html

* Quick file distribution challenge: http://www.advogato.org/article/555.html
