# fselect
Find files with SQL-like queries
[![Crates.io](https://img.shields.io/crates/v/fselect.svg)](https://crates.io/crates/fselect)
[![build](https://github.com/jhspetersson/fselect/actions/workflows/rust.yml/badge.svg)](https://github.com/jhspetersson/fselect/actions/workflows/rust.yml)
### 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, compare results in several directories with [subqueries](docs/usage.md#subqueries-for-in-and-exists)
* aggregate, statistics, date, and other [functions](docs/usage.md#functions)
* search within archives
* `.gitignore`, `.hgignore`, and `.dockerignore` support (experimental)
* search by width and height of images, EXIF metadata
* search by audio metadata (MP3, FLAC, Ogg Vorbis, Opus, M4A/AAC, WAV, AIFF, APE, WavPack, Musepack, Speex)
* search by extended file attributes, POSIX ACLs, and Linux capabilities
* search by file hashes
* search by MIME type
* shortcuts to common file types
* [interactive mode](docs/usage.md#interactive-mode)
* support for `plocate` and `Everything` indexes for lightning-fast search
* various output formatting (CSV, JSON, and others)
More is under way!
### Installation
#### Latest release from source
* Install [Rust with Cargo](https://www.rust-lang.org/en-US/install.html) and its dependencies to build a binary
* Run `cargo install fselect`
You can optionally build with fast, index-backed search support: [voidtools *Everything*](https://www.voidtools.com/)
on Windows (`--features everything`, then pass `--everything`) or [*plocate*](https://plocate.sesse.net/)
on Linux (`--features plocate`, then pass `--plocate`). See the
[usage guide](docs/usage.md#index-backed-search-everything--plocate) for details.

### Documentation
[Detailed description of all the supported features.](docs/usage.md)
### 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"
Search within a directory name with spaces (backticks are also supported):
fselect "name from '/home/user/dir with spaces' where size > 0"
fselect "name from `/home/user/dir with spaces` where size > 0"
Or simply escape the single quote:
fselect name from \'/home/user/dir with spaces\' where size gt 0
Specify the file size, get an 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
fselect name, size from ./tmp where size between 5mb and 6mb
More complex query:
fselect "name from /tmp where (name = *.tmp and size = 0) or (name = *.cfg and size > 1000000)"
You can use subqueries:
fselect "name from /test1 where size > 100 and size in (select size from /test2 where name in (select name from /test3 where modified in (select modified from /test4 where size < 200)))"
fselect "name, path, size from /data as data where exists (select * from /backup as backup where backup.name = data.name)"
A subquery can also be used in the `FROM` clause as the source of the outer query:
fselect "src.name, src.size from (select path from /projects depth 2 where size > 100) as src where src.name like '%.rs'"
Aggregate functions (you can use curly braces if you want and even combine them with the regular parentheses):
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 the 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](https://docs.rs/regex/1.1.0/regex/#syntax) 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 an 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 are possible (find everything updated since May 1st):
fselect path from /home/user where modified gte 2017-05-01
Default is the 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 git 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 images with a known name part but unknown extension:
fselect path from /home/user/projects where name = "*RDS*" and width gte 1
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
Even simpler way of using boolean columns:
fselect path from /home/user where is_doc
fselect path from /home/user where is_image
fselect path from /home/user where is_video
Find files with dangerous permissions:
fselect mode, path from /home/user where other_write or other_exec
fselect mode, path from /home/user where other_all
Simple glob-like expressions or even regular expressions in 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
fselect path from /tmp where is_sticky
fselect path from /tmp where is_pipe
fselect path from /tmp where is_socket
Find files with xattrs, check if a 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'"
Group results:
fselect "ext, count(*) from /tmp group by ext"
fselect "ext, count(*) from /tmp group by 1"
fselect "mime, ext, count(*) from /tmp group by 1, 2"
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
