In my last post I mentioned that I use tcsh. This was a very popular shell on the Ohio State Computer Science Department's Sun 4 and SLC network ca. 1990. It's a supported package under Ubuntu, so it's clearly not dead, at least not entirely. How widely used is it these days? Here's the result from Google Trends:

Google Trends Showing the Decline of tcsh

Clearly the trend is downward. It was about five times as popular as a search term in early 2004 as now. The US ranks eighth in search frequency, and English fifth among languages. I suspect there will come a day when I need to try out a new shell.
