What would happen if someone created a file called INPUT_GIANT_123 rm -rf * .csv?

I fear a simple use of filename=INPUT_GIANT_*.csv might evaluate this as:-

Set the variable filename to INPUT_GIANT_123 and then run rm -rf * .csv

which might not be what you actually want to do. This might not be malicious and could be an error typing on the command line.

You might well be safer to sanitise the input before using it openly.
