I need to print the directory structure of our production system and I would like to remove some specific directories from the tree?

How do we specify multiple ignore patterns for tree command?

You simply provide all the patterns to the -I command, separated by |. From the manpage:

-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.

So, for example

tree -I 'test*|docs|bin|lib'

skips the 'docs', 'bin', and 'lib', directories, and any directory with 'test' in the name, wherever they may lie within the directory hierarchy. Obviously, you can apply wildcards for much more powerful matching.

    Looked at the man page, saw a very terse explanation for "-I", was frustrated. Didn't think to look a few lines above. Thanks. ;) – Tomislav Nakic-Alfirevic Nov 13 '14 at 9:47

  • Thanks! I use this to browse my code from the command line with excluding node_modules. – thevangelist Mar 15 '17 at 15:43

    How can a subdirectory such as docs/subdoc/ be excluded? – user1032531 Dec 25 '17 at 12:39
  • @JitendraVyas: how about tree --prune -P '*.html' You will also get directories, but only those with .html files in them. – fbicknel Aug 22 '18 at 14:57
