Selector index 1 is out of bounds. Index must be >= 1 and <= 0.

[d33tah]

Consider the output of the following command:

$ cat /dev/null | xsv select 1
Selector index 1 is out of bounds. Index must be >= 1 and <= 0.

This might happen in practice when xsv is being fed data from a broken script. It looks like this is the relevant piece of code:

xsv/src/select.rs

Line 315 in 3de6c04

Err(format!("Selector index '{}' for name '{}' is \

Perhaps it would make sense to catch this specific error case and throw an error like "input file is empty"?
