How do I display a tree of things in Bash?

How do I make a tree of all things wit开发者_运维技巧h bash? What is the command?

tree /

or

find / 

Update: @OP, since you have so much trouble with it, how about this alternative. On ubuntu 9.10, you should have bash 4.0 ? so try this

#!/bin/bash
shopt -s globstar
for rdir in /*/
do
    for file in $rdir/**
    do
      echo "$file"
    done
done

you should probably alias this :)

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/ /' -e 's/-/|/'

(Warning: huge output)

$ find . -print | sed -e 's;/*/;|;g;s;|; |;g'

Add alias to ~/.bash_profile

alias tree="find . -print | sed -e 's;/*/;|;g;s;|; |;g'"

tree -R /

and then cry because it's enormous.

On a related note, to stop the command, press CTRL+C

Assuming you want to find something from tree, do

    tree / > tree.txt

Then Ctrl + F it.
