[Koha] git bz setup question

I have followed the instructions on the wiki, but every time I restart my virtual machine I need to repeat the path line before git bz will work. Is there a way to have tat path figured out automatically? nengard@debian:~/kohaclone$ git bz attach -e 6716 HEAD git: 'bz' is not a git command. See 'git --help'. Did you mean one of these? am gc mv rm nengard@debian:~/kohaclone$ PATH=$PATH:/usr/sbin:/usr/bin:/usr/local/bin nengard@debian:~/kohaclone$ git bz attach -e 6716 HEAD Thanks in advance Nicole
