fgr

Rust crates.io MIT licensed

Find & Grep utility with SQL-like query language.

Examples

# Find all files with name equal to sample under the current directory:
fgr -e name=sample

# Find files with containing 's' and 777 permissions:
fgr /home /bin -e 'name=*s* and perm=777'

# Find files with name containing SAMPLE
fgr /home -e 'name="*SAMPLE*"'

# Find files with name containing SAMPLE ignore case
fgr /home -e 'name=i"*SAMPLE*"'

# Find files with name containing SAMPLE (regex)
fgr /home -e 'name=r".+SAMPLE.+"'

# Find files with name containing SAMPLE ignore case (regex)
fgr /home -e 'name=ri".+SAMPLE.+"'

# Find files under the /bin directory not owned by root:
fgr /bin -e 'user > 0'

# Find files under the /bin directory having suid bit (but not limited to):
fgr /bin -e 'perms>4000'

# Find recently accessed files (but not in future):
fgr /home -e 'atime > now - 1h and atime < now'

# Find stuff in files:
fgr /home -e 'type=text and contains=*stuff*'

# Other examples:
fgr /home /bin -e 'name=*s* and perm=777 or (name=*rs and contains=r".+user.is_birthday.*")'
fgr /home /bin -e 'name=*s* and perm=777 or (name=*rs and contains=*birth*)'
fgr /home /bin -e 'ext=so and mtime >= now - 1d'
fgr /home -e 'size>=1Mb and name != *.rs and type=vid'

# xargs & -print0 support
fgr /home -e 'perms=777' -p | xargs -0 -n1 | sort

Features

  • Filter files by:
    • Size
    • Depth
    • Type (text, app, archive, audio, book, doc, font, img, vid)
    • atime, mtime
    • name, extension
    • contents
    • user, group, permissions
  • Timeout IO operations (does not hang parsing files like /sys/kernel/security/apparmor/revision)
  • Regex & Glob name matching
  • Regex & Glob contents matching
  • Nexted expressions
  • Human-readable atime/mtime search patterns
  • .ignore support, thanks to ignore crate

Speed

By default, it acts like the find and visits all directories. Search by name is quite fast

du -h /home
# 98G     /home
# About 100G of .gradle, caches and all the whatnot

sudo sh -c 'echo 1 >/proc/sys/vm/drop_caches'
sudo sh -c 'echo 2 >/proc/sys/vm/drop_caches'
sudo sh -c 'echo 3 >/proc/sys/vm/drop_caches'

fgr /home -e 'name=*sample*' # 1.09s user 2.70s system 169% cpu 2.239 total

sudo sh -c 'echo 1 >/proc/sys/vm/drop_caches'
sudo sh -c 'echo 2 >/proc/sys/vm/drop_caches'
sudo sh -c 'echo 3 >/proc/sys/vm/drop_caches'

find /home -name '*sample*' # 0.71s user 2.09s system 12% cpu 22.156 total

TODO

  • Query precedence evaluation
  • Run command
  • Exclude patterns & default exclude patterns (handling /proc/**/pagemap scenarios)
  • Binary/Text type detector
  • Ignore case searches
  • Error printing
  • Documentation
  • AUR
