Generate a one-time TOTP token, then restore the clipboard after 3 seconds

Typing a word in terminal is easier than digging your phone out, opening your two-factor authentication app and typing the code in manually. This alias copies the one-time code to your clipboard for 3 seconds (long enough to paste it into a web form), then restores whatever was on the clipboard beforehand. This command works on Mac. Replace pbpaste/pbcopy with your distribution's versions.

Convert control codes to visible Unicode Control Pictures

Not better, but more lightweight (sed instead of perl). Above command is reduced due to length restriction of less than 256 characters and entity encoding of "Save" command on this page. This is complete command (best without entity encoding): echo -e '\x2Helo folks\t!\r' | sed "y/\x0\x1\x2\x3\x4\x5\x6\x7\x8\x9\xA\xB\xC\xD\xE\xF\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F\x20/␀␁␂␃␄␅␆␇␈␉␊␋␌␍␎␏␐␑␒␓␔␕␖␗␘␙␚␛␜␝␞␟␠/" ␂Helo␠folks␉!␍ Show Sample Output

Remove duplicate lines from the current copy buffer.

OSX users as well as linux users with copy/paste buffer commands can remove duplicate items from their copy buffer with this command. I use this often when I have to copy a long list of items that I didn't generate, but I need to paste elsewhere in a list that's unique. If retaining the original order of lines isn't important to you, use the following command which is easier to remember. pbpaste | sort | uniq | pbcopy

Get primary IP of the local machine

Plenty of commands out there for finding external IP, but sometimes getting the [internal] IP bound to the NIC handling Internet traffic is useful. Probably not production worthy, but a useful quick kludge. Assumes IPv4 and no fancy routing. Show Sample Output

Dropbox login using only curl, sed and bash

Use the command line to log into Dropbox. You have to replace me@yahoo.com with your Dropbox email (note the URL-encoding of "@" as %40). Also replace my_passwd with your Dropbox password. (Note: special characters in your password (such as #) must be url-encoded. You will get a cookie (stored in file "cookie") that you can use for subsequent curl operations to dropbox, for example curl -b cookie https://www.dropbox.com/home. Debug note: If you want to see what data curl posts, use curl's --trace-ascii flag. Show Sample Output

link=https://www.dropbox.com/login ; curl -b a -c cookie -d "t=$(curl -c a $link | sed -rn 's/.*TOKEN: "([^"]*).*/\1/p')&login_email=me%40yahoo.com&login_password=my_passwd" $link
