개인 적으로 좋아하는 명령어 가 몇개 있는데

그중에 하나가 tree다..

쉽고 직관적이면서도 파워풀하다.

그런데 가끔 서버에서 보면 tree 명령어가 없는 서버들이 있다..

tree 명령어를 쓰면 아래와 같은 디렉코디 구조가 나온다.

NAME
tree - list contents of directories in a tree-like format.

SYNOPSIS
tree [ -adfgilnpqstuxACDFN ] [ -P pattern ] [ -I pattern ] [ directory ... ]

DESCRIPTION
   Tree is a recursive directory listing program that produces a depth indented listing of files. Color is supported ala dircolors
   if the LS_COLORS environment variable is set, output is to a tty, and the -C flag is used. With no arguments, tree lists the
   files in the current directory. When directory arguments are given, tree lists all the files and/or directories found in the
   given directories each in turn. Upon completion of listing all files/directories found, tree returns the total number of files
   and/or directories listed.

By default, when a symbolic link is encountered, the path that the symbolic link refers to is printed after the name of the link
in the format:

name -> real-path

If the `-l' option is given and the symbolic link refers to an actual directory, then tree will follow the path of the symbolic
link as if it were a real directory.

OPTIONS
Tree understands the following command line switches:

-a All files are printed. By default tree does not print hidden files (those beginning with a dot `.'). In no event does
tree print the file system constructs `.' (current directory) and `..' (previous directory).

-d List directories only.

-f Prints the full path prefix for each file.

-i Makes tree not print the indentation lines, useful when used in conjunction with the -f option.

-l Follows symbolic links if they point to directories, as if they were directories.

-x Stay on the current file-system only. Ala find -xdev.

-P pattern
List only those files that match the wild-card pattern. Note: you must use the -a option to also consider those files
beginning with a dot `.' for matching. Valid wildcard operators are `*' (any zero or more characters), `?' (any single
character), `[...]' (any single character listed between brackets (optional - (dash) for character range may be used: ex:
[A-Z]), and `[^...]' (any single character not listed in brackets).
-I pattern
Do not list those files that match the wild-card pattern.

-p Print the protections for each file (as per ls -l).

-s Print the size of each file along with the name.

-u Print the username, or UID # if no username is available, of the file.

-g Print the group name, or GID # if no group name is available, of the file.

-D Print the date of the last modification time for the file listed.

-F Append a `/' for directories, a `=' for socket files, a `*' for executable files and a `|' for FIFO's, as per ls -F

-q Print non-printable characters in filenames as question marks instead of the default caret notation.

-N Print non-printable characters as is instead of the default caret notation.

-t Sort the output by last modification time instead of alphabetically.

-n Turn colorization off always, over-ridden by the -C option.

-C Turn colorization on always, unless the LS_COLORS environment variable is not set. Useful to colorize output to a pipe.

-A Turn on ANSI line graphics hack when printing the indentation lines.

FILES
/etc/DIR_COLORS System color database.
~/.dircolors Users color database.

ENVIRONMENT
LS_COLORS Color information created by dircolors

BUGS
None known. Not heavily tested. Needs a few more options, ala ls.
