Check your bash shell for vulnerability to the ShellShock exploit
If this command prints 'x' then your shell is vulnerable. Null output confirms that you are protected. Further reading: http://allanmcrae.com/2014/09/shellshock-and-arch-linux/

gain all mp3s in subfolders w/o encoding
This will search all subfolders for mp3's and gain them to more or less sane defaults (without reencoding). http://mp3gain.sourceforge.net/ required!

install all archive file type apps in ubuntu

prevent accidents while using wildcards
alternative for "echo rm *.txt". Just doubletab the command you are willing to use and it will show you the affected files.

Scrape commands from commandline fu's 1st page
just bored here at work ... if your are daring ... add '| bash' .... enjoy require 'ruby'

Filter the output of a file continously using tail and grep
The OPs solution will work, however on some systems (bsd), grep will not filter the data, unless the --line-buffered option is enabled.

Replace underscores with spaces in filenames and dirnames, recursively into subdirs.
Everyone wants to take spaces out of filenames. Forget that. I want to put them back in. We've got tools and filesystems that support spaces, they look better, so I'm going to use them. Because of how find works I find I need to run this multiple times, if it's renaming subdirs. But it can be re-run without issues. I got this version of the command from a comment in this underscore-generating command. http://www.commandlinefu.com/commands/view/760/find-recursively-from-current-directory-down-files-and-directories-whose-names-contain-single-or-multiple-whitespaces-and-replace-each-such-occurrence-with-a-single-underscore. All I did was change the regex.

View all images
So you are in directory with loads of pictures laying around and you need to quickly scan through them all

Opens files containing search term in vim with search term highlighted
Takes the same arguments that ack does. E.g. ack-open -i "searchterm" opens all files below the current directory containing the search term. The search term is also highlighted within vim if you have hlsearch set. Works on zsh, unsure if it works on bash. Note: ubuntu users have to change ack to ack-grep unless you already have it aliased (as I do)

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
