Remove BOM (Byte Order Mark) from text file

Takes file (text.txt), removes BOM from it, and outputs the result to a new file (newFile.txt). BOM is "Byte Order Mark" ([http://en.wikipedia.org/wiki/Byte_order_mark]), an invisible, non-breaking, zero-length character. In other words, if you see a DIFF with "" at the beginning, you've got a byte order mark, which can't be removed without this command or a hex editor. It can appear for a number of reasons, such as getting copied to/from a UNIX filesystem...

Open a file in a GTK+ dialog window

I use zenity because it's a rewrite of gdialog and also replaces gmessage and has more useful options. Using --text-info allows you to select and copy the text to your clipboard. To see a file in a list dialog: cat /etc/passwd | zenity --width 800 --height 600 --list --column Entries If you don't have zenity, you'll have to download it via apt-get install zenity, etc.

Get the IP address of a machine. Just the IP, no junk.

Why use many different utilities all piped together, when you only need two?

Backup with versioning

Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by EVACopy http://evacopy.sourceforge.net

Display Dilbert strip of the day

Requires display. Corrected version thanks to sputnick and eightmillion user.

(Debian/Ubuntu) Discover what package a file belongs to

Works similar to dpkg -S, but uses the locatedb and is thus inarguably a lot faster - if the locatedb is current.

Revert back all files currently checked out by Perforce SCM for edit

Debug pytest failures in the terminal

pudb is an ncurses debugger. This command will allow interactive debugging of test failures in pytest using pudb.

Downsample mp3s to 128K

This will lower the quality of mp3 files, but is necessary to play them on some mobile devices.

Detect illegal access to kernel space, potentially useful for Meltdown detection

Based on capsule8 agent examples, not rigorously tested

ssh to machine behind shared NAT

Useful to get network access to a machine behind shared IP NAT. Assumes you have an accessible jump host and physical console or drac/ilo/lom etc access to run the command. Run the command on the host behind NAT then ssh connect to your jump host on port 2222. That connection to the jump host will be forwarded to the hidden machine. Note: Some older versions of ssh do not acknowledge the bind address (0.0.0.0 in the example) and will only listen on the loopback address.
