在Linux中列出可由羣組寫入的文件和目錄

Question

在給定目錄及其子目錄中遞歸列出文件的最簡單方法是什麼？它們可由擁有它們的組寫入？我使用Debian 5.

Answer 1

喜歡的東西

find /dir/ -perm /g=w 

或者，如ls -l輸出

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

Answer 2

find /dir/ -perm /0020也是一個很好的解決方案。檢查手冊頁以查找。我在Debian中的版本（find（GNU findutils）4.4.0）有Sorpigal的論點作爲棄用。

-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.
