Welcome to the cbird wiki! Just random stuff for now

Using filters

Filters can be used for a few things, but usually it is

• limit scope of the search
• remove or certain results

Limiting the scope

Say you know that the originals were taken before a certain date, so you only want to find duplicates of these. You can use -with to select the subset, then search within the subset using "@" to refer to it.

cbird -select-type i -with exif#Photo.DateTimeOriginal#todate '<2022-01-03' -similar-to @

You have a project folder that is known to have copies of your assets/originals folder, and you don't want to include it. You can use a regular expression to select the search set, then search within it.

cbird -select-all -without relPath ':^projects/.*' -similar-in @

Using Expressions

Boolean tests on properties (v0.7.1)

• -with name '~foo || ~bar' == "name contains foo or bar"
• -with name '~foo && ~bar' == "name contains foo and bar"

Type conversions for metadata properties to enable correct evaluation (v0.7.1)

• -with exif#Photo.DateTimeOriginal#todate '>=2021-01-01 && <2022-02-01'
• date is sometime in January 2021

Comparison with the needle property (v0.7.1)

• -similar-to ./originals -with res '==%needle' -with suffix '==%needle' -with fileSize '<%needle'
• assume dupes are of lower quality due to smaller size at the same resolution and file type
