Set the iTerm tab title to the current directory, not full path.
# put this in your .bash_profile
if [ $ITERM_SESSION_ID ]; then
export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
fi
# Piece-by-Piece Explanation:
# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
# the $PROMPT_COMMAND environment variable is executed every time a command is run
# see: ss64.com/bash/syntax-prompt.html

Moving git repository and all its branches, tags to a new remote repository keeping commits history
#!/bin/bash
# Sometimes you need to move your existing git repository
# to a new remote repository (/new remote origin).
# Here are a simple and quick steps that does exactly this.
#
# Let's assume we call "old repo" the repository you wish
# to move, and "new repo" the one you wish to move to.
#
### Step 1. Make sure you have a local copy of all "old repo"
### branches and tags.

BASH Script to keep Route53 updated with your current external IP address
#!/bin/bash
# (optional) You might need to set your PATH variable at the top here
# depending on how you run this script
#PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
# Hosted Zone ID e.g. BJBK35SKMM9OE
ZONEID="enter zone id here"
# The CNAME you want to update e.g. hello.example.com
