fselect

Find files with SQL-like queries

Why use fselect?

While it doesn't tend to fully replace traditional find and ls, fselect has these nice features:

• complex queries
• SQL-like (not real SQL, but highly relaxed!) grammar easily understandable by humans
• shortcuts to common file types

More is under way!

Installation

• Install Rust with Cargo and its dependencies to build a binary
• Run cargo install fselect

...or download a statically precompiled binary from Github if you are on a modern Windows 64bit

Examples

Find images (full path and size):

fselect path, size from /home/user where name = *.jpg or name = *.png

Find files (just names) with any content (size > 0):

fselect name from /home/user/tmp where size gt 0

or put arguments into the quotes:

fselect "name from /home/user/tmp where size > 0"

Specify file size:

fselect path from /home/user where size gt 2g
fselect path from /home/user where size = 5m
fselect path from /home/user where size lt 8k

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 path from '/home/user/Misc stuff' where name != 'Some file'

Regular expressions supported:

fselect name from /home/user where path ~= .*Rust.*

And even simple glob will suffice:

fselect name from /home/user where path = *Rust*

Find files by creation date:

fselect path from /home/user where created = 2017-05-01

Be more specific to match all files created at 3PM:

fselect path from /home/user where created = '2017-05-01 15'

And even more specific:

fselect path from /home/user where created = '2017-05-01 15:10'
fselect path from /home/user where created = '2017-05-01 15:10:30'

Date and time intervals possible (find everything updated since May 1st):

fselect path from /home/user where modified gte 2017-05-01

Default is current directory:

fselect path, size where name = *.jpg

Search within multiple locations:

fselect path from /home/user/oldstuff, /home/user/newstuff where name = *.jpg

With maximum depth specified:

fselect path from /home/user/oldstuff depth 5 where name = *.jpg
fselect path from /home/user/oldstuff depth 5, /home/user/newstuff depth 10 where name = *.jpg

Shortcuts to popular file extensions:

fselect path from /home/user where is_archive = true
fselect path from /home/user where is_audio = 1
fselect path from /home/user where is_image = false
fselect path from /home/user where is_video != true
