Following on from my gpx2tcx AWK script and Windows batch file, I now present what will probably the last separate component in the series... my gpx2tcx.sh Bash shell script.

This script is similar in nature to the Windows equivalent presented earlier, however it is considerably more flexible. Unlike the Windows batch file, this Bash script supports a number of command line arguments that allow its operation to be tweaked more easily.

I recently came across a number of forum topics asking how to calculate CPU usage from /proc/stat, which raised a very slight sense of challenge within me (was just in "the mood" to do some BASH scripting)... so, here's an example showing how to calculate CPU usage with a simple BASH script.
