dtree

Command line program to draw trees

For installation instructions, see the file INSTALL.

Manual

See https://strahinja.srht.site/man/dtree/dtree.1.html.

Examples

Format a tree using double-stroke box drawing characters:

printf "A\n\tB\n\t\tC\n\tD\n" | dtree -sd

tree(1) replacement:

find . -print | sed -E "s,[^/]+/,$(printf '\t'),g" | dtree

same, using ASCII characters:

find . -print | sed -E "s,[^/]+/,$(printf '\t'),g" | dtree -sa

poor man's findmnt(1) (depends on having /proc/mounts active):

sort -k2 /proc/mounts |
awk 'BEGIN{ pp=0 } {		# pp = previous pointer
	sl = $2;
	gsub("[^/]", "", sl);
	slashc = length(sl);	# slash count
	if ($2 != "/" &&
		substr($2,0,length(prev[pp])) == prev[pp])
	{
		if (prev[pp] == "/" || slashc > prevsc[pp])
			pp++;
		for (i = 0; i < pp; i++)
			printf "\t";
		prev[pp] = $2;		# previous mountpoint
		prevsc[pp] = slashc;	# previous slash count
	}
	else if ($2 != "/")
	{
		if (slashc < prevsc[pp] &&
			substr($2,0,length(prev[pp-1])) != prev[pp-1])
			pp--;
		prev[pp] = $2;
		prevsc[pp] = slashc;
		for (i = 0; i < pp; i++)
			printf "\t";
	}
	else
	{
		prev[pp] = $2;
		prevsc[pp] = slashc;
	}
	print $2;
}' |
dtree

On OpenBSD, replace the first command in the above pipeline with

mount |

and the parameter $2 with $3.

Prerequisites

C compiler - defaults in config.mk (HaikuOS needs Clang/LLVM)

Install

$ git clone https://git.sr.ht/~strahinja/dtree
$ cd dtree
$ cp config.$(uname -s) config.mk
$ su
# make install

With got:

$ got clone https://git.sr.ht/~strahinja/dtree
$ got checkout dtree.git
$ cd dtree
$ cp config.$(uname -s) config.mk
$ su
# make install

Persistent build configuration file

The file config.mk will be sourced when building targets which also accept configuration through environment variables. For example, CPPFLAGS and PREFIX are specified in config.mk.

Initially, there will be no config.mk, you will need to copy one of the customized config.* files or write your own:

$ cp config.$(uname -s) config.mk || echo Write config.mk from scratch

Install (Arch)

$ git clone https://aur.archlinux.org/dtree.git
$ cd dtree
$ makepkg -si
