Why Bash Scripting?

• As geophysicists, we are frequently forced to

• Obtain quick statistics from an existing large data bank,

• Extract the required data from a large volume of data,

• Convert automatically large volume of data to different formats (e.g., convert SEED seismic waveforms to SAC),

• Do sensitivity analysis by running a given program for different possible range of input parameters,

• Draw complex GMT plots,

• Do parallel computing
