I've got a file that's full of VT100 color codes, which is making it hard to search. Is there a unix utility that can strip those out so I'm left with plain text?
I've got a bash script that would be nicer if when I prompt the user, rather than just asking for input, if it provided a line that the user could edit (but a full text editor would be overkill, it's only one line)
What tool provides this?
dialog's inputbox is almost right, but I'd rather it didn't paint the whole screen.
How do I export a list of installed Debian packages on a system, and then install those same packages on a new system?
I have a Debian server that allows users to log in. I don't mind them accessing the web or downloading files, but I want to otherwise restrict their internet access from that machine. How should I set up my IPTABLES or other firewall to make this work easily?
I'm sure there's a well-known answer for this, but I can't seem to find it.
How do I make a user's PHP scripts (in ~user/public_html, for example), run as the owner rather than as (eg) www-data?
Assume Apache, Linux, and PHP 5.
