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’.
