Khph is a tool for managing collections of files from the command line. It allows you to tag files via links, and query your collection with a simple query language.
Khph is for when you just want to tag your recent trip's photos, without worrying about what all-in-one program to use, or how it stores its metadata. With khph, the file system is the database.
Suppose ~/Pictures contains all of your photos, unorganized. With some minor setup:
$ cd ~/Pictures
$ echo 'sourceDirs: [all]' >.khph
$ mkdir all
$ mv *.* all/
We can then start tagging photos: (using shell brace expansion)
$ khph --tag-create /people/{me,friends} /places/{home,beach}
$ khph --tag-add me --files DSCN0001.jpg DSCN0003.jpg --print-file-actions
ln -s ../../all/DSCN0001.jpg ~/Pictures/people/me/DSCN0001.jpg
ln -s ../../all/DSCN0003.jpg ~/Pictures/people/me/DSCN0003.jpg
$ khph --tag-add home --files DSCN{0001..0004}.jpg
$ khph --tag-add beach friends --files DSCN{0005..0007}.jpg
... and so on ...
After that, we can make various useful queries:
(Look at all photos of myself or my family:)
$ khph --list 'tag at "me" or at "family"' | xargs geeqie
(Create a tag containing photos of people at my home:)
$ khph --realize /results 'tag atbelow "people" and tag atbelow "home"'
(Recreate the tag to contain yet-untagged photos:)
$ khph --realize /results 'no tag'
(Delete the tag, we're done with it:)
$ rm -r results
The query syntax is flexible and is described in full in the readme⤴.
