|LR(1)||General Commands Manual||LR(1)|
lris a versatile tool to generate file listings with configurable formatting, ordering and filtering.
When no path is given or path is an empty string, the current directory is used by default.
The special path argument
read file names from standard input, instead of traversing
path. Likewise, the special path
lr read file names from
The options are as follows:
- Output filenames separated by NUL bytes. Likewise, read input filenames separated by NUL bytes.
- Output filenames and an indicator of their file type (one of
- Long output a la ‘
ls -l’ (implies
-l, print atime.
-l, print ctime.
-l, print mtime. This is the default.
- Output inspired by BSD stat(1) (implies
- Custom formatting, see FORMATTING.
- Use breadth first traversal. For each depth of the directory tree, files are sorted and printed, then the next depth is looked at.
- Use depth first traversal.
prunewill not work, but
totalare computed on the fly.
- Only follow symlinks on command line (default: don't follow symlinks).
- Follow all symlinks.
- Don't go below one level of directories.
- Don't list files starting with a dot.
- Quote file names using Austin Group #249 syntax
- Quote file names (default for output to TTY).
- Don't enter directories.
- Colorize output to TTY. Use twice to force colorized output. If the
NO_COLORis set, colors are never used.
- Output OSC 8 hyperlinks to TTY. Use twice to force hyperlinks.
- Print human readable size for
- Strip directory prefix passed on command line.
- Don't enter other filesystems.
- Don't sort results.
- Sort according to ord, see SORT ORDER.
- Only show files where basename matches the POSIX ERE regex.
- Only show files matching the expression test, see
TESTS. Multiple occurrences of
-eare regarded as a conjunction.
- Behaves as if path was passed like an ordinary
argument, but overrides the color of the file names to the number
color which must be between 0 and 255 (default: 2,
lrformat strings support the following escape sequences:
- Special characters as in C.
- Byte with one, two or three-digit octal value.
- Byte with one or two-digit hexadecimal value.
- A plain ‘%’.
- File size in bytes
- File size, with human readable unit
- File size in 512-byte blocks
- File size in 1024-byte blocks
- Path depth
- Device number (stat.st_dev)
- Device ID for special files (stat.st_rdev)
- Inode number
- One space character for every depth level
- Full path (
- Full path without command line argument prefix
- Symlink target
- Number of hardlinks
- File indicator type symbol (one of

- Octal file permissions

SORT ORDER¶Sort order is string consisting of the following letters. Uppercase letters reverse sorting. Default sort order is ‘
- path depth
- file extension
- inode number
- file name
- directory name
- file size
- file type. This sorts all directories before other files.
- File name as version numbers (sorts ‘2’ before ‘10’).
Sn’ sorts first by
size, smallest last, and then by name (in case sizes are equal).
lrtests are given by the following EBNF:
