A couple weeks ago I started noticing my terminal was weirdly slow to startup. I never understood why people cared about terminal latency until I had to wait literally several seconds after opening my terminal to start typing. I thought it was because I had installed oh my zsh and it was doing something funky at startup. Looking into it more I realized that I had unthinkingly pasted an echo '...' >> ~/.zshrc command into my .zshrc instead of running it on the command line. So every time I ran my terminal, it was not only running the same line hundreds of times, it was appending one more line. I now appreciate a fast terminal startup much more after the experience.
