Check These Out
OK, not the most useful but a good way to impress friends. Requires the "display" command from ImageMagick.
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
I've seen a lot of overly complicated attempts at figuring out "where am I?"
I think this is a part of the problem:
type -a pwd
force the use of the binary version of `pwd` instead of the built-in with "/bin/pwd -P"
-P option provides an absolute path to the present working directory
for the overly cautious type:
$(which pwd) -P
Show all columns except 5th. This might help you save some typing if you are trying to exclude some columns from the output.

I wasted two hours reading the sox documentation and searching on the web for the format of some obscure fscking sound sample, and then finally came up with this. This plays only the first three seconds of your unknown formatted sound file using every one of sox's built-in filetypes. If you don't get an exact match, you may get close.
.
I could not fit every single type in and keep it under 127 characters, so you will have to replace "..." with the full list obtainable by `$ sox --help` (or try `Show sample output`)
.
note: /usr/bin/play should be linked to sox on most systems.
You're running a program that reads LOTS of files and takes a long time.
But it doesn't tell you about its progress.
First, run a command in the background, e.g.
$ find /usr/share/doc -type f -exec cat {} + > output_file.txt
Then run the watch command.
"watch -d" highlights the changes as they happen
In bash: $! is the process id (pid) of the last command run in the background.
You can change this to $(pidof my_command) to watch something in particular.
Problem: I wanted to backup user data individually, using and incremental method. In this example, all user data is located in "/mnt/storage/profiles", and about 25 folders inside, each with a username ( /mnt/storage/profiles/mike; /mnt/storage/profiles/lucy ...)
I need each individual folder backed up, not the whole "/mnt/storage/profiles". So, using find while excluding directories depth and creating two variables (tarfile=username & desdir=destination), tar will create a .tgz file for each folder, resulting in a "mike_2013-12-05.tgz" and "lucy_2013-12-05.tgz".
