http://askubuntu.com – Hey guys I made a very useful application using Bash script I am so excited about it, I wonder can I package this bash script as an installable .Deb package and give it to people to install it ? [I would want my bash script to be copied to the bin folder so it be run able] another question is, if I be able to do that, what should I do to list my program in software center? (HowTos)
