Liste des fichiers et des répertoires accessibles en écriture pour le groupe sous Linux

Question

Quel est le moyen le plus simple de répertorier de manière récursive les fichiers d'un répertoire donné et de ses sous-répertoires, accessibles en écriture pour le groupe propriétaire? J'utilise Debian 5.

Answer 1

Quelque chose comme

find /dir/ -perm /g=w 

Ou, pour la sortie comme ls -l

find /dir/ -perm /g=w -exec ls -lLd {} + 

Answer 2

find /dir/ -perm /0020 est aussi une bonne solution. Vérifiez la page de manuel pour trouver. Ma version dans Debian (find (GNU findutils) 4.4.0) a l'argument de Sorpigal comme obsolète.

-perm mode 
      File's permission bits are exactly mode (octal or symbolic). 
      Since an exact match is required, if you want to use this form 
      for symbolic modes, you may have to specify a rather complex 
      mode string. For example -perm g=w will only match files which 
      have mode 0020 (that is, ones for which group write permission 
      is the only permission set). It is more likely that you will 
      want to use the `/' or `-' forms, for example -perm -g=w, which 
      matches any file with group write permission. See the EXAMPLES 
      section for some illustrative examples. 

    -perm -mode 
      All of the permission bits mode are set for the file. Symbolic 
      modes are accepted in this form, and this is usually the way in 
      which would want to use them. You must specify `u', `g' or `o' 
      if you use a symbolic mode. See the EXAMPLES section for some 
      illustrative examples. 

    -perm /mode 
      Any of the permission bits mode are set for the file. Symbolic 
      modes are accepted in this form. You must specify `u', `g' or 
      `o' if you use a symbolic mode. See the EXAMPLES section for 
      some illustrative examples. If no permission bits in mode are 
      set, this test currently matches no files. However, it will 
      soon be changed to match any file (the idea is to be more con- 
      sistent with the behaviour of -perm -000). 

    -perm +mode 
      Deprecated, old way of searching for files with any of the per- 
      mission bits in mode set. You should use -perm /mode instead. 
      Trying to use the `+' syntax with symbolic modes will yield sur- 
      prising results. For example, `+u+x' is a valid symbolic mode 
      (equivalent to +u,+x, i.e. 0111) and will therefore not be eval- 
      uated as -perm +mode but instead as the exact mode specifier 
      -perm mode and so it matches files with exact permissions 0111 
      instead of files with any execute bit set. If you found this 
      paragraph confusing, you're not alone - just use -perm /mode. 
      This form of the -perm test is deprecated because the POSIX 
      specification requires the interpretation of a leading `+' as 
      being part of a symbolic mode, and so we switched to using `/' 
      instead.
