find filenames NOT ending in specific extensions on Unix

Question

Is there a simple way to recursively find all files in a directory hierarchy  that do not end in a list of extensions  E g  all files that are not   dll or   exe  UNIX GNU find  powerful as it is  doesn t seem to have an exclude mode  or I m missing it   and I ve always found it hard to use regular expressions to find things that don t match a particular expression   I m in a Windows environment  using the GnuWin32 port of most GNU tools   so I m equally open for Windows-only solutions

find        -name    exe  -o -name    dll

User · Answer

find   -name    exe -o -name    dll -o -print   The first two -name options have no -print option  so they skipped  Everything else is printed

Linux OS X   Starting from the current directory  recursively find all files ending in  dll or  exe  find   -type f   grep -P    dll    exe     Starting from the current directory  recursively find all files that DON T end in  dll or  exe  find   -type f   grep -vP    dll    exe     Notes    1  The P option in grep indicates that we are using the Perl style to write our regular expressions to be used in conjunction with the grep command  For the purpose of excecuting the grep command in conjunction with regular expressions  I find that the Perl style is the most powerful style around    2  The v option in grep instructs the shell to exclude any file that satisfies the regular expression   3  The   character at the end of say   dll   is a delimiter control character that tells the shell that the filename string ends with   dll

You could do something using the grep command   find     grep -v   dll exe      The -v flag on grep specifically means  find things that don t match this expression

Other solutions on this page aren t desirable if you have a long list of extensions -- maintaining a long sequence of -not -name  this  -not -name  that  -not -name  other  would be tedious and error-prone -- or if the search is programmatic and the list of extensions is built at runtime   For those situations  a solution that more clearly separates data  the list of extensions  and code  the parameters to find  may be desirable   Given a directory  amp  file structure that looks like this      -- a      -- 1 txt      -- 15 xml      -- 8 dll      -- b             -- 16 xml             -- 2 txt             -- 9 dll             -- c                 -- 10 dll                 -- 17 xml                 -- 3 txt      -- d             -- 11 dll             -- 18 xml             -- 4 txt             -- e                 -- 12 dll                 -- 19 xml                 -- 5 txt      -- f          -- 13 dll          -- 20 xml          -- 6 txt          -- g              -- 14 dll              -- 21 xml              -- 7 txt   You can do something like this      data section  list undesired extensions here declare -a  BADEXT  xml dll      code section  this never changes BADEXT     IFS       echo     BADEXT        sed  s       g     find   -type f   -regex         BADEXT      Which results in     a 1 txt   a b 2 txt   a b c 3 txt   a d 4 txt   a d e 5 txt   a f 6 txt   a f g 7 txt   You can change the extensions list without changing the code block   NOTE doesn t work with native OSX find - use gnu find instead

Or without   and the need to escape it   find   -not -name    exe  -not -name    dll    and to also exclude the listing of directories  find   -not -name    exe  -not -name    dll  -not -type d   or in positive logic  -   find   -not -name    exe  -not -name    dll  -type f
