Convert filenames from ISO-8859-1 to UTF-8

Warn: use convmv or detox if you can: they are the right tools. But if you want to do it manually, you can use this command to find the problematic files and transliterate their accented characters to their ascii equivalent. (Useful when doing cd backup: growisofs may fail on files which come from the old iso8859-* days.)

Do not clear the screen after viewing a file with less

From the manpage: $ man less -X or --no-init Disables sending the termcap initialization and deinitialization strings to the terminal. This is sometimes desirable if the deinitialization string does something unnecessary, like clearing the screen. Bonus: If you want to clear the screen after viewing a file this way that had sensitive information, hit or just type clear. Since is readily available, I don't know why less bothers to automatically clear. If you're viewing the file at all, chances are you want to see the output from it after you quit.

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

Based on capsule8 agent examples, not rigorously tested

Test file system performance

You need bonnie++ package for this. More detail than a simple hdparm -t /dev/sda would give you. the -d is the directory where it performs writes/reads for example I use /tmp/scratch with 777 permissions Bonnie++ benchmarks three things: data read and write speed, number of seeks that can be performed per second, and number of file metadata operations that can be performed per second.

Spoof your wireless MAC address on OS X to 00:e2:e3:e4:e5:e6

If you want to check that the spoof worked, type the same command as earlier: $ifconfig en1 | grep ether Now you will see: $ether 00:e2:e3:e4:e5:e6 For the wired ethernet port: $sudo ifconfig en0 ether 00:e2:e3:e4:e5:e6

shell equivalent of a boss button

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

en/decrypts files in a specific directory

To decrypt the files replace "ccenrypt" with "ccdecrypt. ccrypt(1) must be installed. It uses the AES (Rijndael) block cipher. To make it handier create an alias.
