cvs add files recursively – not already in repository

When you have a lot of files in some repository and you have added a couple of new, in CVS there is no command to add just the new ones to the repository, so here is a workaround for that.

cvs status 2>/dev/null | awk '{if ($1=="?")print "cvs add -kb " $2}'

Well, if you are adding text files then you might want to remove the “-kB” in the cvs command above.

configure firewall – the easy way.

It is good practice to keep iptables/firewall enabled. But configuring it is difficult, do you agree. Not any more 🙂

Install firewall-config

sudo yum install firewall-config

This will install a GUI application, which you can run with “Firewall” application in the dash or with “firewall-config” in terminal. It is pretty straight forward to use this tool, even if you don’t have much knowledge on Firewall/iptables.
