TREE(1) General Commands Manual TREE(1) NAME tree - list contents of directories in a tree-like format. SYNOPSIS tree [-acdfghilnpqrstuvxACDFQNSUX] [-L level [-R]] [-H baseHREF] [-T title] [-o filename] [--nolinks] [-P pattern] [-I pattern] [--inodes] [--device] [--noreport] [--dirsfirst] [--version] [--help] [--filelimit #] [--si] [--prune] [--du] [--timefmt format] [--matchdirs] [--] [directory ...] DESCRIPTION Tree is a recursive directory listing program that produces a depth indented listing of files, which is colorized ala dircolors if the LS_COLORS environment variable is set and output is to tty. With no arguments, tree lists the files in the current directory. When direc- tory arguments are given, tree lists all the files and/or directories found in the given directories each in turn. Upon completion of list- ing 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 sym- bolic link refers to is printed after the name of the link in the for- mat: 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: LISTING OPTIONS -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. -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. -f Prints the full path prefix for each file. -x Stay on the current file-system only. Ala find -xdev. -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. -P pattern List only those files that match the wild-card pattern. Note: you must use the -a option to also consider those files begin- ning 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. .TP --ignore-case If a match pattern is specified by the -P or -I option, this will cause the pattern to match without regards to the case of each letter. --matchdirs If a match pattern is specified by the -P option, this will cause the pattern to be applied to directory names (in addition to filenames). In the event of a match on the directory name, matching is disabled for the directory's contents. If the --prune option is used, empty folders that match the pattern will not be pruned. --prune Makes tree prune empty directories from the output, useful when used in conjunction with -P or -I. See BUGS AND NOTES below for more information on this option. --noreport Omits printing of the file and directory report at the end of the tree listing. --charset charset Set the character set to use when outputting HTML and for line drawing. --filelimit # Do not descend directories that contain more than # entries. --timefmt format Prints (implies -D) and formats the date according to the format string which uses the strftime(3) syntax. -o filename Send output to filename. FILE OPTIONS -q Print non-printable characters in filenames as question marks instead of the default. -N Print non-printable characters as is instead of as escaped octal numbers. -Q Quote the names of files in double quotes. -p Print the file type and permissions for each file (as per ls -l). -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. -s Print the size of each file in bytes along with the name. -h Print the size of each file but in a more human readable way, e.g. appending a size letter for kilobytes (K), megabytes (M), gigabytes (G), terabytes (T), petabytes (P) and exabytes (E). --si Like -h but use SI units (powers of 1000) instead. --du For each directory report its size as the accumulation of sizes of all its files and sub-directories (and their files, and so on). The total amount of used space is also given in the final report (like the 'du -c' command.) This option requires tree to read the entire directory tree before emitting it, see BUGS AND NOTES below. Implies -s. -D Print the date of the last modification time or if -c is used, the last status change time for the file listed. -F Append a `/' for directories, a `=' for socket files, a `*' for executable files, a `>' for doors (Solaris) and a `|' for FIFO's, as per ls -F --inodes Prints the inode number of the file or directory --device Prints the device number to which the file or directory belongs SORTING OPTIONS -v Sort the output by version. -t Sort the output by last modification time instead of alphabeti- cally. -c Sort the output by last status change instead of alphabetically. Modifies the -D option (if used) to print the last status change instead of modification time. -U Do not sort. Lists files in directory order. Disables --dirs- first. -r Sort the output in reverse order. This is a meta-sort that alter the above sorts. This option is disabled when -U is used. --dirsfirst List directories before files. This is a meta-sort that alters the above sorts. This option is disabled when -U is used. --sort[=]<name> Sort the output by name (as per ls): name (default), ctime (-c), mtime (-t), size or version (-v). GRAPHICS OPTIONS -i Makes tree not print the indentation lines, useful when used in conjunction with the -f option. Also removes as much whitespace as possible when used with the -J or -x options. -A Turn on ANSI line graphics hack when printing the indentation lines. -S Turn on CP437 line graphics (useful when using Linux console mode fonts). This option is now equivalent to `--charset=IBM437' and may eventually be depreciated. -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 col- orize output to a pipe. XML/JSON/HTML OPTIONS -X Turn on XML output. Outputs the directory tree as an XML format- ted file. -J Turn on JSON output. Outputs the directory tree as an JSON for- matted array. -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://hostname.organiza- tion.domain/pub' (baseHREF should be `ftp://hostname.organiza- tion.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 style-sheet, 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. --nolinks Turns off hyperlinks in HTML output. MISC OPTIONS --help Outputs a verbose usage listing. --version Outputs the version of tree. -- Option processing terminator. No further options will be pro- cessed after this. FILES /etc/DIR_COLORS System color database. ~/.dircolors Users color database. ENVIRONMENT LS_COLORS Color information created by dircolors TREE_COLORS Uses this for color information over LS_COLORS if it is set. TREE_CHARSET Character set for tree to use in HTML mode. LC_CTYPE Locale for filename output. LC_TIME Locale for timefmt output, see strftime(3). TZ Timezone for timefmt output, see strftime(3). AUTHOR Steve Baker (email@example.com) HTML output hacked by Francesc Rocher (firstname.lastname@example.org) Charsets and OS/2 support by Kyosuke Tokoro (NBG01720@nifty.ne.jp) BUGS AND NOTES Tree does not prune "empty" directories when the -P and -I options are used by default. Use the --prune option. The -h and --si options round to the nearest whole number unlike the ls implementations which rounds up always. Pruning files and directories with the -I, -P and --filelimit options will lead to incorrect file/directory count reports. The --prune and --du options cause tree to accumulate the entire tree in memory before emitting it. For large directory trees this can cause a significant delay in output and the use of large amounts of memory. The timefmt expansion buffer is limited to a ridiculously large 255 characters. Output of time strings longer than this will be undefined, but are guaranteed to not exceed 255 characters. XML/JSON trees are not colored, which is a bit of a shame. Probably more.
