2.2 - Filters and Special Characters in Queries

For Get-style actions (-GC, -GR, -GP, -GF, -GT), Info options are interpreted as query filters that specify the conditions used to query GDEXDB. Four characters refine those filters; quote or escape them on the command line so the shell does not consume them:

‘!’

negate the match. Must appear immediately after the option name (may need escaping as ‘!’ in some shells due to history expansion).

‘<’

less-than comparison against the next value.

‘>’

greater-than comparison against the next value.

‘<>’

range between the next two values (inclusive).

The combination “’!’ ‘<’ value” expresses ‘greater than or equal to value’.
