do you know about linux command ls?
let me tell you about it
according to linux
ls – list directory contents


ls [OPTION]… [FILE]…


List information about the FILEs (the current directory by default).
Sort entries alphabetically if none of -cftuSUX nor –sort.

Mandatory arguments to long options are mandatory for short options

-a, –all
do not hide entries starting with .

-A, –almost-all
do not list implied . and ..

print the author of each file

-b, –escape
print octal escapes for nongraphic characters

use SIZE-byte blocks

-B, –ignore-backups
do not list implied entries ending with ~

-c with -lt: sort by, and show, ctime (time of last modification of
file status information) with -l: show ctime and sort by name
otherwise: sort by ctime

-C list entries by columns

some more about ls

control whether color is used to distinguish file types. WHEN
may be ‘never’, ‘always’, or ‘auto’

-d, –directory
list directory entries instead of contents, and do not derefer-
ence symbolic links

-D, –dired
generate output designed for Emacs’ dired mode

-f do not sort, enable -aU, disable -lst

-F, –classify
append indicator (one of */=@|) to entries

across -x, commas -m, horizontal -x, long -l, single-column -1,
verbose -l, vertical -C

like -l –time-style=full-iso

-g like -l, but do not list owner

-G, –no-group
inhibit display of group information

-h, –human-readable
print sizes in human readable format (e.g., 1K 234M 2G)

–si likewise, but use powers of 1000 not 1024

-H, –dereference-command-line
follow symbolic links listed on the command line

follow each command line symbolic link

that points to a directory

–indicator-style=WORD append indicator with style WORD to entry names:
none (default), classify (-F), file-type (-p)

-i, –inode
print index number of each file

-I, –ignore=PATTERN
do not list implied entries matching shell PATTERN

-k like –block-size=1K

-l use a long listing format

-L, –dereference
when showing file information for a symbolic link, show informa-
tion for the file the link references rather than for the link

-m fill width with a comma separated list of entries

-n, –numeric-uid-gid
like -l, but list numeric UIDs and GIDs

-N, –literal
print raw entry names (don’t treat e.g. control characters spe-

-o like -l, but do not list group information

-p, –file-type
append indicator (one of /=@|) to entries

-q, –hide-control-chars
print ? instead of non graphic characters

show non graphic characters as-is (default unless program is
‘ls’ and output is a terminal)

-Q, –quote-name
enclose entry names in double quotes

use quoting style WORD for entry names: literal, locale, shell,
shell-always, c, escape

-r, –reverse
reverse order while sorting

-R, –recursive
list subdirectories recursively

-s, –size
print size of each file, in blocks

-S sort by file size

extension -X, none -U, size -S, time -t, version -v

status -c, time -t, atime -u, access -u, use -u

show time as WORD instead of modification time: atime, access,
use, ctime or status; use specified time as sort key if

show times using style STYLE: full-iso, long-iso, iso, locale,

FORMAT is interpreted like ‘date’; if FORMAT is FORMAT1FORMAT2, FORMAT1 applies to non-recent files and FORMAT2 to
recent files; if STYLE is prefixed with ‘posix-’, STYLE takes
effect only outside the POSIX locale

-t sort by modification time

-T, –tabsize=COLS
assume tab stops at each COLS instead of 8

-u with -lt: sort by, and show, access time with -l: show access
time and sort by name otherwise: sort by access time

-U do not sort; list entries in directory order

-v sort by version

-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

Now let’s code

script for listing ls -l

(bash copy)
if [ $# -eq 1 ]
read -p "Enter the filename: " filen
if [ -a "$filen" ]
IFS=" "
outp=(`ls -lh $filen`)
echo "Name of the file input/entered: $filen"
echo "Permission bits are: "${outp[0]}
echo "Number of links are: "${outp[1]}
echo "Owner User Id(UID) is: "${outp[2]}
echo "Owner Group Id(GID) is: "${outp[3]}
echo "File Size is: "${outp[4]}
echo "Last Modified Time is: "${outp[*]:5:3}
echo "Name of File is: "${outp[8]}
