Linuxll command parameters

If the-cftuvSUX or -- sort option is not specified, it is sorted by letter size. Usage: ls [option]... [file]...
List FILE information (the current directory by default ).
If the-cftuvSUX or -- sort option is not specified, it is sorted by letter size.


Parameters required for long options are also required for short options.
-A, -- all does not hide any project that starts.
-A, -- almost-all: list any projects...
-- Author and-l list the authors of each file at the same time
-B, -- escape represents unprintable characters in an octal overflow sequence
-- Block-size = size block, in bytes of the specified size
-B, -- ignore-backups does not list any "~ "End Project
-C with-lt: Sort by ctime and display ctime (file
Time when the status was last changed)
Combined with-l: The ctime is displayed, but sorted by name. other cases: sorted by ctime
-C. list projects from top to bottom in each column
-- Color [= WHEN] controls whether to use color to distinguish files. WHEN can be
"Never" (default), "always", or "auto"
-D, -- directory: list the files in the directory rather than in the directory when a directory is encountered.
-D, -- dired generates results suitable for the dired mode of Emacs
-F is not sorted, The-aU option takes effect, and The-lst option is invalid.
-F, -- classify plus the file type indicator (*/= @ | one of them)
-- Format = staggered-x keywords, separated by commas (,)-m, horizontal-x, long-l,
Watermark-1, detailed-l, vertical-C
-- Full-time:-l -- time-style = full-iso
-G is similar to-l, but the owner is not listed.
-- Group-directories-first
Group directories before files. This option can be used with -- sort,
However, once -- sort = none (-U) is used, the group is disabled.
-G, -- no-group is in the form of a long list, and no group name is output
-H, -- human-readable and-l together, output the file size in an easy-to-read format
(For example, 1 K 234 M 2G)
-- Si is similar to the above, but 1000 is used as the base instead of 1024.
-H, -- dereference-command-line
Symbolic links listed by the command line
-- Dereference-command-line-symlink-to-dir
Symbolic links to directories listed by the command line
-- Hide = PATTERN: hide a project that meets the PATTERN.
(-A or-A will overwrite this option)
-- Indicator-style = specifies the method of adding an indicator after each project name:
None (default), classify (-F), file-type (-p)
-I, -- inode: displays the inode number of each file
-I, -- ignore = PATTERN does not display any project that meets the specified shell PATTERN
-K is -- block-size = 1 K
-L use a long format to list information
-L, -- dereference: when the file information of the symbolic link is displayed, the symbolic link indicates
Object instead of the information of the symbolic link.
-M all items are separated by commas (,) and the whole row width is filled.
-N, -- numeric-uid-gid is similar to-l, but UID and GID are listed.
-N, -- literal outputs unprocessed project names (for example, do not specially process control characters)
-O is similar to-l, but does not list information about the group.
-P, -- indicator-style = slash: add the symbol "/" to the directory "/"
-Q, -- hide-control-chars "? "Replace the characters that cannot be printed
-- Show-control-chars: displays unprintable characters directly (this is the default mode unless you call
The program name is "ls" and the result is output on the terminal)
-Q, -- quote-name enclose the entry name in double quotation marks
-- Quoting-style =: Use the specified quoting method to display the name of the entry:
Literal, locale, shell, shell-always, c, escape
-R, -- reverse order reserved
-R, -- recursive display subdirectory
-S, -- size displays the size allocated to each file in the form of blocks
-S sort by file size
-- Sort = Below is an optional WORD and the corresponding options they represent:
Extension-X status-c
None-U time-t
Size-S atime-u
Time-t access-u
Version-v use-u
-- Time = when both WORD and-l are used, the time represented by WORD is displayed instead of the time when it is modified.
: Atime, access, use, ctime, or status; and
-- Sort = time takes the specified time as the sorting keyword.
-- Time-style = when using STYLE and-l simultaneously, the time is displayed according to the format represented by STYLE:
Full-iso, iso, locale, posix-iso, and + FORMAT.
FORMAT is the time FORMAT used by "date". if FORMAT
Is FORMAT1 <换行> FORMAT2, FORMAT1 applies to older versions
While FORMAT2 applies to newer files; if the STYLE
If it starts with "posix-", the STYLE is only outside the POSIX language.
Effective.
-T sort by modification time
-T, -- tabsize = width specifies the width of the Tab, not 8 characters
-T sort by modification time
-T, -- tabsize = COLS specifies the width of the Tab, not 8 characters
-U used with-lt: sorted by access time and displayed
Use with-l: Display access time and sort by file name
Others: Sort by access time
-U is not sorted. projects are listed in the directory order.
-V sorts numbers (versions) in the text.
-W, -- width = COLS assume screen width instead of current value
-X list entries by lines instead of by columns
-X sort alphabetically by entry extension
-1 list one file per line


SELinux options:


-- Lcontext Display security context. Enable-l. Lines
Will probably be too wide for most displays.
-Z, -- context Display security context so it fits on most
Displays. Displays only mode, user, group,
Security context and file name.
-- Scontext Display only security context and file name.
-- Help: displays the help information and exits.
-- Version: displays the version information and exits.


SIZE can be an optional integer followed by one of the following units:
KB 1000, K 1024, MB 1000*1000, M 1024*1024, G, T, P, E, Z, Y.


The feature that uses color to differentiate file types has been disabled. it is disabled by default with -- color = never.
With the -- color = auto option, ls generates the color code only when the standard output is connected to the terminal.
You can use the dircolors command to set the LS_COLORS environment variable.




Exit status:
0 normal
1. general problem (for example, the sub-folder cannot be accessed)
2. serious problems (for example, command line parameters cannot be used)
