Broadcast Copy

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

Usage

To make file availabe for copying:

$ ./bcp filename

To receive the file:

$ ./bcp

bcpdir: to send directories

# zip directory to /tmp and bcp it
bcpdir() {

	curr_time=`date +%s`
	file=/tmp/files_$curr_time.zip

	if [[ -d $1 ]]; then

		# dir	
		cd $1
		zip -r -9 $2 $file .

	elif [[ -f $1 ]]; then

		# single file
		file_dir=`dirname $1`
		file_name=`basename $1`
		cd $file_dir
		zip -r -9 $2 $file $file_name

	else

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
