it can be very useful to visually distinguish shell sessions based on type.

did you know you can change your terminal emulator profile for different connections? say for example, you’re using ssh - you can wire up a quick function to change profiles on the fly:

# credit https://coderwall.com/p/s-2_nw/change-iterm2-color-profile-from-the-cli # add this to your shell profile set_iterm_profile () { echo -e " \0 33]50;SetProfile= $1 \a " }

source your shell profile source ~/.bash_profile

now lets say you have 2 iterm profiles ‘default’ and ‘deploy’

you can set up an alias to run set_iterm_profile deploy and your ssh command in sequence:

alias @deploy='set_iterm_profile deploy; ssh user@host; set_iterm_profile default;'

now your terminal emulator will set the new profile whenever you use the alias to connect to a box. when disconnecting, your profile will stitch back to your default :)

you’ll end up with something like this:

another option is to override the ssh method so it defaults to this behavior, but I prefer the simplicity of aliasing.

some amazing iterm2 profile designs

iterm2 is a highly customizable terminal emulator for mac osx and ships with many options to tailor appearance.

rainbow tab colors with iterm2

tab color can also be altered

iterm2 also lets you modify tab color to differentiate between sessions. check out my project https://github.com/lfender6445/iterm2_rainbow_tabs for randomized tab colors
