List the contents of directories in a tree-like format.
| --help |
Outputs a verbose usage listing. |
| --version |
Outputs the version of tree. |
| -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. Symbolic links that will result in recursion are avoided when detected. |
| -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) and `|' separates
alternate patterns. |
| -I pattern |
Do not list those files that match the wild-card pattern. |
| --noreport |
Omits printing of the file and directory report at the end of the tree listing. |
| -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. |
| --inodes |
Prints the inode number of the file or directory |
| --device |
Prints the device number to which the file or directory belongs |
| -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 carrot notation. |
| -N |
Print non-printable characters as is instead of the default carrot notation. |
| -r |
Sort the output in reverse alphabetic order. |
| -t |
Sort the output by last modification time instead of alphabetically. |
| --dirsfirst |
List directories before files. |
| -n |
Turn colorization off always, over-ridden by the -C option. |
| -C |
Turn colorization on always, using built-in color defaults if 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. |
| -S |
Turn on ASCII line graphics (useful when using linux console mode fonts). This option is now equivalent to
`--charset=IBM437' and will eventually be depreciated. |
| -L level |
Max display depth of the directory tree. |
| -R |
Recursively cross down the tree each level directories (see -L option), and at each of them execute tree again adding `-o 00Tree.html' as a new option. |
| -H baseHREF |
Turn on HTML output, including HTTP references. Useful for ftp sites. baseHREF gives the base ftp location when using HTML output. That is, the local directory may be `/local/ftp/pub', but it must be referenced as `ftp://host-name.organization.domain/pub'
(baseHREF should be `ftp://hostname.organization.domain'). Hint: don't use ANSI lines with this option, and don't give more than one directory in the directory list. If you wish to use colors via CCS stylesheet, use the -C option in addition to this option to force color output. |
| -T title |
Sets the title and H1 header string in HTML output mode. |
| --charset charset |
Set the character set to use when outputting HTML and for line drawing. |
| --nolinks |
Turns off hyperlinks in HTML output. |
| -o filename |
Send output to filename. |
tree
Simply running the command without any option will
give a tree output of the current directory and alls sub
directories. Therefore if you're at root
it's not a good idea to run this command alone otherwise it will
list every file and directory on the computer.
tree -L 1
List the directories and files in the current
directory. Below is an example of what this may look like.
