I would like to know the total size of Ubuntu repository with individual repository-component (Main, Universe, Multiverse, Restricted) sizes for:
- 32-bit platform.
- 64-bit platform.
I have made Ubuntu my primary OS since 10.04, and I have converted many of my friends and neighbors into Ubuntu users since then. I am the fix-it guy they approach when they encounter problems. The most frantic calls I get are when they encounter an "update-induced kernel panic." (Many human beings are allergic to command-line interfaces and search engines.)
What are the step-by-step procedures to resolve an "update-induced kernel panic"?
Is there any difference between the behavior of gksu foo and gksudo foo?
Can they be used interchangeably?
The first time a user enters sudo foo, sudo_root prompts for the password. For a certain duration after that, sudo_root doesn't prompt for a password for any subsequent sudo foo's in that terminal session.
- What duration is that?
- Can the duration be changed?
I recently (re)stumbled upon this: Linux Trojan Goes Unnoticed For Almost A Year (Unreal IRCd)
Yes, I know that adding some random PPA/software from an untrusted source is asking for trouble (or worse). I never do that, but many do (many Linux blogs and tabloids promote adding PPAs for fancy apps, without warning that it may break your system or worse still, compromise your security.)
How can a trojan horse or a rogue application/script be detected and removed?
I just found out about the free the fish easter egg available in Ubuntu:
Press Alt + F2
Enter this: free the fish
Are there any more easter eggs available in Ubuntu? What are they?
How do I split a 7GB (movie) file into smaller files of (say) 1GB, and then (in another Ubuntu computer) integrate them to get the original file (using just bash commands)?
