comment What is the difference between building from source and using an install package?
@ultrasawblade - You're obviously not paranoid enough! <G> - see cm.bell-labs.com/who/ken/trust.html for the full monty.

comment Is there a downside to deleting all of the broken symbolic links in a system?
One more possible reason for a broken symlink: a symlink to an actual file that only exists some of the time. E.g. in a work flow with deep paths, you might have a symlink to a work file (for convenience) which is deleted when the work flow is complete, but will be recreated during the next use of that work flow. /dev/modem is kind of like that because the actual device file it points to only exists when the physical device is connected.

comment Why doesn't the sudo command need the root password?
Just found sudo logging in /var/log/auth.log - along with a lot of other stuff including some IPs from China trying to get root ssh access to my system - so, if you just want to see sudo, you have to filter it through grep or similar.

comment Coloring different sources for tail
In addition to the great answers below, you may also want to check out unix.stackexchange.com/questions/26313/colored-find-output which shows how to do much more with colorizing output files.

comment Why doesn't the sudo command need the root password?
I haven't explored this, but I understand one of the features of sudo that su does not have is that it (is able to?) keep a log of what commands were run by which user to make it easier to trace problems back to their sources. I just looked on my kubuntu system and do not see such a log, so maybe this is not a default behavior.

comment How does Linux choose which application to open a file?
+1 for mentioning the file utility. It's very handy when things don't make sense.

comment How to write bash script to configure my displays when HDMI is plugged in or unplugged
I just upgraded from kubuntu 12.04 to 14.04.1. I was waiting to comment because I was hoping that would help, but nothing has changed. I still have to switch audio manually. I think I'll open a new question on SE Ask Ubuntu. I don't think any audio switches. I just tried vlc, dragonplayer, and amarok.

comment How to delete this undeletable directory?
+1 for persistence! And for thorough documentation of everything you tried. We don't usually get to see what didn't work, but it's often very valuable to know.

comment Is it possible to define a command in bash?
Not an expert at this, but shouldn't something like this (hopefully, something more useful) be put in /usr/local/bin?

comment How is file owner and group remembered for an external drive?
+1 for the chmod technique I hadn't thought of - in addition to being correct otherwise.

comment “tree” command output with “pure” (7-bit) ASCII output
Thanks for the question. I needed this so I could pipe the output of tree into enscript to get contol of the print formatting (using dprint/dprintm from my duplexpr package sourceforge.net/projects/duplexpr/.)

comment An alternative to `xdotool type`
Since you were using xdotool, you are in a gui, but it would help to know what distro and desktop environments you are using.
