tree

Show the contents of the current directory as a tree. More information: http://mama.indstate.edu/users/ice/tree/.

• Print files and directories up to 'num' levels of depth (where 1 means the current directory):
  tree -L {{num}}
• Print directories only:
  tree -d
• Print hidden files too with colorization on:
  tree -a -C
• Print the tree without indentation lines, showing the full path instead (use -N to not escape non-printable characters):
  tree -i -f
• Print the size of each file and the cumulative size of each directory, in human-readable format:
  tree -s -h --du
• Print files within the tree hierarchy, using a wildcard (glob) pattern, and pruning out directories that don't contain matching files:
  tree -P '{{*.txt}}' --prune
• Print directories within the tree hierarchy, using the wildcard (glob) pattern, and pruning out directories that aren't ancestors of the wanted one:
  tree -P {{directory_name}} --matchdirs --prune
• Print the tree ignoring the given directories:
  tree -I '{{directory_name1|directory_name2}}'
