Find files with SQL-like queries
Find images:
fselect name, size from /home/user where name = *.jpg or name = *.png
Find files with any content:
fselect name from /home/user/tmp where size gt 0
or
fselect "name from /home/user/tmp where size > 0"
More complex query:
fselect name from /tmp where (name = *.tmp and size = 0) or (name = *.cfg and size gt 1000000)
Use single quotes if you need to address files with spaces:
fselect name from '/home/user/Misc stuff' where name != 'Some file'
