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. |
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.
List the directories and files in the current
directory. Below is an example of what this may look like.
