git-ftp.sh: Pushing changed files to a website via FTP
I scripted a small but useful shell tool named git-ftp.sh licensed under GPL v3 helps you saving time while pushing changed files to a ftp server. It uses git to find out which files have been changed since the last upload.
If you have multiple branches, which is very common with git, it also finds changed files between those branches. It also deletes files on ftp server which were deleted in the local git repo. It does only upload and delete git tracked files.
Some more features:
- Option -D: dry-run, so you can see what would happen
- Option -a: Forces to upload all files
- Option -i: Enter the FTP password interactively
- Shows a warning if you are not on master branch
Let’s have a look at git-ftp.sh in action:

Postfix: Host not found, try again
Small hint from me: If you set up Postfix to relay your mails and your relay host does not have an MX record (anymore), mailq has a lot of mails on standby and you see something like:
Jul 14 12:45:39 myhostname postfix/smtp[2349]: 74FBF30501:
to=
status=deferred (Name service error for name=recip.domain
type=MX: Host not found, try again)
And found this FAQ on Posfix.org and you say: “Yeah, the FAQ is right but so what now?”. Just boot your VI editor and open $ vi /etc/postfix/main.cf and change relayhost = smtp.myhostname.org:587 to relayhost = [smtp.myhostname.org]:587 and perform /etc/init.d/posfitx reload so Postfix will not looking for a valid MX record anymore. After this, go to the important work again…
