Sending & Receiving Binary Files Via Bash On Linux

Sending & Receiving Binary Files Via Bash On Linux


There will be 1 video and on the video it is in 2 parts (no markings)

The 1st part is for sending image.gif

the second part is project called anyfile so you can send files other than image.gif (feel free to modify the script)!


There will be 4 sets of code, one for server and 1 for client for each part as explained above

for sending image.gif client

Code:

#!/bin/bash
# (c) J~NET
#  Usage: ./nc_client.sh
clear
echo "Binary Client Reciever"

echo -en "\e[92mPlease Wait \c"
sudo nc -l -p 777 > newimage.gif
count=0
total=34
pstr="[=======================================================================]"

while [ $count -lt $total ]; do
  sleep 0.06 # this is work
  count=$(( $count + 1 ))
  pd=$(( $count * 73 / $total ))
  printf "\r%3d.%1d%% %.${pd}s" $(( $count * 100 / $total )) $(( ($count * 1000 / $total) % 10 )) $pstr
done

echo "All Done!"


Server for above

Code:


#!/bin/bash
# (c) J~NET
# Usage: ./nc_server.sh
clear
echo "Binary Server AKA SENDER"
clear
echo -en "\e[92mPlease Wait \c"
sudo cat image.gif | nc localhost 777
count=0
total=34
pstr="[=======================================================================]"

while [ $count -lt $total ]; do
  sleep 0.06 # this is work
  count=$(( $count + 1 ))
  pd=$(( $count * 73 / $total ))
  printf "\r%3d.%1d%% %.${pd}s" $(( $count * 100 / $total )) $(( ($count * 1000 / $total) % 10 )) $pstr
done
echo "File Sent!"

For any file Sending (the client side wont know the extension so resolving that will be be coming soon!



Client side for anyfile sending

Code:

#!/bin/bash
# (c) J~NET
#
clear
echo "Binary Client Reciever"

echo -en "\e[92mPlease Wait \c"
sudo nc -l -p 777 > output
count=0
total=34
pstr="[=======================================================================]"

while [ $count -lt $total ]; do
  sleep 0.06 # this is work
  count=$(( $count + 1 ))
  pd=$(( $count * 73 / $total ))
  printf "\r%3d.%1d%% %.${pd}s" $(( $count * 100 / $total )) $(( ($count * 1000 / $total) % 10 )) $pstr
done

echo "All Done!"


Server

Code:

#!/bin/bash
# (c) J~NET
#
# Usage: ./nc_server.sh "file.ext"
myvar="$@"
clear
echo "Binary Server AKA SENDER"
clear
echo -en "\e[92mPlease Wait \c"
sudo cat $myvar | nc localhost 777
count=0
total=34
pstr="[=======================================================================]"

while [ $count -lt $total ]; do
  sleep 0.06 # this is work
  count=$(( $count + 1 ))
  pd=$(( $count * 73 / $total ))
  printf "\r%3d.%1d%% %.${pd}s" $(( $count * 100 / $total )) $(( ($count * 1000 / $total) % 10 )) $pstr
