If you want to change your iTerm2 ZSH shell's theme/color scheme when you SSH into a server, follow these directions below.
Create 2 Profiles:
* Your personal preference theme (can be named anything)
* SSH color theme (must be named SSH)
Go into your ~/.oh-my-zsh/custom directory and create a new file entitled iTerm2-ssh.zsh. Copy and paste the following or copy from the repo:
function tabc() {
NAME=$1; if [ -z "$NAME" ]; then NAME="Default"; fi
# if you have trouble with this, change
# "Default" to the name of your default theme
echo -e "\033]50;SetProfile=$NAME\a"
}
function tab-reset() {
NAME="YOUR_CUSTOM_PROFILE_NAME_HERE"
echo -e "\033]50;SetProfile=$NAME\a"
trap - INT EXIT
}
function colorssh() {
if [[ -n "$ITERM_SESSION_ID" ]]; then
trap "tab-reset" INT EXIT
if [[ "$*" =~ "web*|production|ec2-.*compute-1" ]]; then
tabc SSH
fi
fi
ssh $*
}
compdef _ssh tabc=ssh
alias ssh="colorssh"The breakdown of this code:
function tabc() grabs the ssh name after the command $ ssh is entered. This
changes the SetProfile name to ssh.
tab-reset() is responsible for when you exit the ssh session to return back to
a profile name of your choosing. Remember to create a custom profile name and replace
the YOUR_CUSTOM_PROFILE_NAME_HERE with your profile name.
colorssh determines when to change the SetProfile name. Currently it will
changes to the ssh profile when the following values exist after $ ssh.
- web *
- production
- ec2-.*compute-1
