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:
- SQL-like (not real SQL, but highly relaxed!) grammar easily understandable by humans
- complex queries
- aggregate, statistics, date, and other functions
- search within archives
.gitignore,.hgignore, and.dockerignoresupport (experimental)- search by width and height of images, EXIF metadata
- search by MP3 info
- search by extended file attributes
- search by file hashes
- search by MIME type
- shortcuts to common file types
- interactive mode
- various output formatting (CSV, JSON, and others)
More is under way!

Documentation
More detailed description. Look at examples first.
Examples
Find temporary or config files (full path and size):
fselect size, path from /home/user where name = '*.cfg' or name = '*.tmp'
Windows users may omit the quotes:
fselect size, path from C:\Users\user where name = *.cfg or name = *.tmp
Or put all the arguments into the quotes like this:
fselect "name from /home/user/tmp where size > 0"
Find files (just names) with any content (size > 0):
fselect name from /home/user/tmp where size gt 0
Specify file size, get absolute path, and add it to the results:
cd /home/user
fselect size, abspath from ./tmp where size gt 2g
fselect fsize, abspath from ./tmp where size = 5m
fselect hsize, abspath from ./tmp where size lt 8k
More complex query:
fselect "name from /tmp where (name = *.tmp and size = 0) or (name = *.cfg and size > 1000000)"
Aggregate functions:
fselect "MIN(size), MAX(size), AVG(size), SUM(size), COUNT(*) from /home/user/Downloads"
Formatting functions:
fselect "LOWER(name), UPPER(name), LENGTH(name), YEAR(modified) from /home/user/Downloads"
Get the year of an oldest file:
fselect "MIN(YEAR(modified)) from /home/user"
Use single quotes if you need to address files with spaces:
fselect "path from '/home/user/Misc stuff' where name != 'Some file'"
Regular expressions of Rust flavor are supported:
fselect name from /home/user where path =~ '.*Rust.*'
Negate regular expressions:
fselect "name from . where path !=~ '^\./config'"
Simple globs expand automatically and work with = and != operators:
fselect name from /home/user where path = '*Rust*'
Classic LIKE:
fselect "path from /home/user where name like '%report-2018-__-__???'"
Exact match operators to search with regexps disabled:
fselect "path from /home/user where name === 'some_*_weird_*_name'"
Find files by date:
fselect path from /home/user where created = 2017-05-01
fselect path from /home/user where modified = today
fselect path from /home/user where accessed = yesterday
fselect "path from /home/user where modified = 'apr 1'"
fselect "path from /home/user where modified = 'last fri'"
Be more specific to match all files created at interval between 3PM and 4PM:
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 minimum and/or maximum depth specified (depth is a synonym for maxdepth):
fselect path from /home/user/oldstuff depth 5 where name = '*.jpg'
fselect path from /home/user/oldstuff mindepth 2 maxdepth 5, /home/user/newstuff depth 10 where name = '*.jpg'
Optionally follow symlinks:
fselect path, size from /home/user symlinks where name = '*.jpg'
Search within archives (currently only zip-archives are supported):
fselect path, size from /home/user archives where name = '*.jpg'
Or in combination:
fselect size, path from /home/user depth 5 archives symlinks where name = '*.jpg' limit 100
Enable .gitignore or .hgignore support:
fselect size, path from /home/user/projects gitignore where name = '*.cpp'
fselect size, path from /home/user/projects hgignore where name = '*.py'
Search by image dimensions:
fselect CONCAT(width, 'x', height), path from /home/user/photos where width gte 2000 or height gte 2000
Find square images:
fselect path from /home/user/Photos where width = height
Find old-school rap MP3 files:
fselect duration, path from /home/user/music where genre = Rap and bitrate = 320 and mp3_year lt 2000
Shortcuts to common file extensions:
fselect path from /home/user where is_archive = true
fselect path, mime from /home/user where is_audio = 1
fselect path, mime from /home/user where is_book != false
fselect path from /home/user where is_doc != 1
fselect path from /home/user where is_image = false
fselect path from /home/user where is_video != true
Find files with dangerous permissions:
fselect mode, path from /home/user where other_write = true or other_exec = true
fselect mode, path from /home/user where other_all = true
Simple glob-like expressions or even regular expressions on file mode are possible:
fselect mode, path from /home/user where mode = '*rwx'
fselect mode, path from /home/user where mode =~ '.*rwx$'
Find files by owner's uid or gid:
fselect uid, gid, path from /home/user where uid != 1000 or gid != 1000
Or by owner's or group's name:
fselect user, group, path from /home/user where user = mike or group = mike
Find special files:
fselect name from /usr/bin where suid = true
fselect path from /tmp where is_pipe = true
fselect path from /tmp where is_socket = 1
Find files with xattrs, check if particular xattr exists, or get its value:
fselect "path, has_xattrs, has_xattr(user.test), xattr(user.test) from /home/user"
Include arbitrary text as columns:
fselect "name, ' has size of ', size, ' bytes'"
Order results:
fselect path from /tmp order by size desc, name
fselect modified, fsize, path from ~ order by 1 desc, 3
Finally limit the results:
fselect name from /home/user/samples limit 5
Format output:
fselect size, path from /home/user limit 5 into json
fselect size, path from /home/user limit 5 into csv
fselect size, path from /home/user limit 5 into html
