EnvTool v1.2:

Build Status

A tool to search along various environment variables for files (or a wildcard). The following modes handles these environment variables: screenshot

It also checks for missing directories along the above env-variables.

The --path option also checks these registry keys: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths and HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths

and enumerates all keys for possible programs. E.g. if registry contains this: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\makensis.exe = f:\MinGW32\bin\MingW-studio\makensis.exe,

envtool --path maken* will include f:\MinGW32\bin\MingW-studio\makensis.exe in the result.

Problem with old programs pestering your PATH and Registry entries can be tricky to diagnose. Here I had an problem with an old version of the FoxitReader PDF reader: Checking with envtool --path foxit*.exe, resulted in:

  Matches in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths:
   (2)  27 Nov 2014 - 10:24:04: f:\ProgramFiler\FoxitReader\FoxitReader.exe
  Matches in %PATH:
        21 Apr 2006 - 17:43:10: f:\util\FoxitReader.exe
   (2): found in "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths".

Hence if you write FoxitReader in the Window Run-box (Winkey-R), you'll get the newer (27 Nov 2014) FoxitReader launched. But if you say FoxitReader in your shell (cmd etc.), you'll get the old version (21 Apr 2006).

Other examples:

E.g. 1: envtool --path notepad*.exe first checks the %PATH% env-var for consistency (reports missing directories in %PATH%) and prints all the locations of notepad*.exe. On my box the result is:

Thu Jul 21 16:02:20 2011: f:\windows\system32\notepad-orig.exe
Mon Nov 18 19:26:40 2002: f:\windows\system32\notepad.exe
Thu Jul 21 16:13:11 2011: f:\windows\system32\notepad2.exe
Mon Nov 18 19:26:40 2002: f:\windows\notepad.exe

E.g. 2: envtool --inc afxwin* first checks the %INCLUDE% env-var for consistency (reports missing directories in %INCLUDE) and prints all the locations of afxwin*. On my box the result is:

Thu Apr 14 18:54:46 2005: g:\vc_2010\VC\AtlMfc\include\AFXWIN.H
Thu Apr 14 18:54:46 2005: g:\vc_2010\VC\AtlMfc\include\AFXWIN1.INL
Thu Apr 14 18:54:46 2005: g:\vc_2010\VC\AtlMfc\include\AFXWIN2.INL
Thu Apr 14 18:54:46 2005: g:\vc_2010\VC\AtlMfc\include\AFXWIN.H
Thu Apr 14 18:54:46 2005: g:\vc_2010\VC\AtlMfc\include\AFXWIN1.INL
Thu Apr 14 18:54:46 2005: g:\vc_2010\VC\AtlMfc\include\AFXWIN2.INL

E.g. 3: If an App Paths registry key has an alias for a command, the target program is printed. E.g. if: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\winzip.exe points to c:\PROGRA~1\WINZIP\winzip32.exe

(here winzip.exe is an alias for the real program winzip32.exe). Hence envtool --path winzip* reports:

Fri Oct 11 09:10:00 2002: f:\PROGRA~1\WINZIP\winzip.exe !
Fri Oct 11 09:10:00 2002: f:\PROGRA~1\WINZIP\winzip32.exe !
(!) - found in registry.

E.g. 4: It's pretty amazing what the FindFile() API in Windows can do. E.g.: envtool --path *-?++.exe:

Tue Nov 19 12:01:38 2002: f:\Mingw32\bin\mingw32-c++.exe
Tue Nov 19 12:01:38 2002: f:\Mingw32\bin\mingw32-g++.exe
Wed Mar 09 14:39:05 2011: f:\CygWin\bin\i686-pc-cygwin-c++.exe
Wed Mar 09 14:39:05 2011: f:\CygWin\bin\i686-pc-cygwin-g++.exe

Although not as powerful as "POSIX-style file matching" which is also built-in via the fnmatch() function.

E.g. 5: If you have Python installed, the --python option will search in %PYTHONPATH and sys.path[] for a match. E.g.: envtool.exe --python ss*.py:

24 Jun 2011 - 11:38:10: f:\ProgramFiler\Python27\lib\ssl.py
16 Feb 2011 - 12:14:28: f:\ProgramFiler\Python27\lib\site-packages\win32\lib\sspi.py
16 Feb 2011 - 12:14:28: f:\ProgramFiler\Python27\lib\site-packages\win32\lib\sspicon.py

E.g. 6: The --python option will also look inside Python _EGG_s (plain ZIP-files) found in sys.path[]. E.g.: envtool.exe --python socket.py:

27 Mar 2013 - 16:41:58: stem\socket.py  (%PYTHONHOME\lib\site-packages\stem-1.0.1-py2.7.egg)
30 Apr 2014 - 09:54:04: f:\Programfiler\Python27\lib\socket.py

E.g. 7: The --evry option combined with the --regex (or -r) is quite powerful. To find all directories with Unix man-pages, you can do this: envtool.exe --evry -r "man[1-9]$":

<DIR> 03 Jun 2014 - 17:56:08: f:\CygWin\usr\share\man\man1\
<DIR> 03 Jun 2014 - 17:56:08: f:\CygWin\usr\share\man\man3\
<DIR> 03 Jun 2014 - 17:56:08: f:\CygWin\usr\share\man\man5\
<DIR> 03 Jun 2014 - 17:56:08: f:\CygWin\usr\share\man\man7\
<DIR> 03 Jun 2014 - 17:56:08: f:\CygWin\usr\share\man\man8\

(assuming you have only 1 set of man-pages from a CygWin install)

Or to find only foo*.bar files under directory-branch(es) misc, you can do:

envtool.exe --evry -r "misc\\.*\\foo.*\.bar"

Or how much space is wasted in your Python cach-files. This would tell you quickly:

  envtool.exe --evry -sD __pycache__*
  ...
  592 matches found for "__pycache__*". Totalling 125 MB (131,391,488 bytes).

E.g. 8: More than one option-mode can combined. For example: envtool.exe --man --evry awk*.[1-9]*:

Matches in %MANPATH:
      13 Mar 2011 - 19:47:43: f:\CygWin\usr\share\man\man1\awk.1.gz (f:\CygWin\usr\share\man\man1\gawk.1)
      09 Dec 1997 - 17:55:20: e:\djgpp\share\man\man1\awk.1
      15 Dec 2004 - 02:06:32: e:\djgpp\share\man\cat1\awk.1
Matches from EveryThing:
<DIR> 24 May 2014 - 12:48:16: e:\DJGPP\gnu\awk-1.3-3\
      09 Dec 1997 - 17:55:20: e:\DJGPP\share\man\man1\awk.1
<DIR> 01 Sep 2014 - 17:49:32: f:\MingW32\msys32\var\lib\pacman\local\awk-1.6-1\

E.g. 9: All modes support showing the file-owner. Or only specific owners.
For example: envtool.exe --path --owner=Admin* --owner=S-1-5* add* could return:

Matches in %PATH:
      25 Jun 2015 - 17:46:39: Administratorer  f:\MingW32\TDM-gcc\bin\addr2line.exe
      01 Jun 2013 - 08:05:42: S-1-5-21...1001  f:\MingW32\bin\addr2line.exe
      17 Aug 2001 - 22:04:02: Administratorer  f:\ProgramFiler\Support-Tools\addiag.exe
      04 Nov 1999 - 09:45:44: Administratorer  f:\ProgramFiler\RKsupport\addiag.exe
      19 Jan 2018 - 00:12:23: Administratorer  f:\gv\dx-radio\UHD\host\bin\addr_test.pdb

The inverse envtool.exe --path --owner=!Admin* is also possible; showing files on the
%PATH who's owner does not match Admin*.

Changes:

  0.1:  Initial version.

  0.2:  Added file date/time stamp. Check for suffix or trailing
        wildcard in file-specification. If not found add a trailing "*".

  0.3: Handled the case where an env-var contains the current directory.
        E.g. when "PATH=./;c:\util", turn the "./" into CWD (using 'getcwd()')
        for 'stat("/.")' to work. Turn off command-line globbing in MinGW
        ('_CRT_glob = 0').

  0.4:  Rudimentary check for Python 'sys.path' searching.

  0.5:  Add a directory search spec mode ("--dir foo*.bar" searches for
        directories only). Better handling of file-specs with a sub-directory
        part. E.g. "envtool --python win32\Demos\Net*".

  0.6:  Add support for POSIX-style file matching (using fnmatch() from djgpp).
        E.g. a file-spec can contain things like "foo/[a-d]bar".
        Note: it doesn't handle ranges on directories. Only ranges on directories
              withing Pyhon EGG-files are handled.

        Improved Python 'sys.path' searching. Uses zipinfo.exe and looks inside
        Python EGG-files (zip files) for a match.

  0.7:  Improved Python 'sys.path' searching. Look inside Python EGGs and ZIP-files
        for a match (this uses the zipinfo external program).
        Add colour-output option '-C'.

  0.8:  New option '--pe' outputs version info from resource-section. E.g.:
          envtool --path --pe vcbuild.*
          Matches in %PATH:
               19 Mar 2010 - 15:02:22: g:\vc_2010\VC\vcpackages\vcbuild.dll
               ver 10.0.30319.1

  0.9:  Cosmetic changes in debug-output ('-d') and command-line parsing.

  0.92: Added option "--evry" to check matches in Everything's database.
        This option queries the database via IPC.
        Ref. http://www.voidtools.com/support/everything/

  0.93: The "--python" option now loads Python dynamically (pythonXX.dll)
        and calls 'PyRun_SimpleString()' to execute Python programs.

  0.94: Fixes for '--evry' (EveryThing database) searches.
        Drop '-i' option.
        Add  '-r' option.

  0.95: Tweaks for better 'fnmatch()' matches.
        Improved '--evry' Regular Expression (--regex) searches.
        Build the MSVC-version using '-MT' (drop the dependency on MSVC1*.DLL)

  0.96: Better Python embedding; lookup python.exe in env-var %PYTHON, then on
        %PATH. Test for correct Python DLL. Report full name of python.exe in
        "envtool -V".

  0.97: Lots of improvements. Print more details on "envtool -VV" (compiler and
        linker flags).

  0.98: Added option "--man" to search for matches in all *subdir* of %MANPATH%.
        E.g. subdirs "man[1-9]" and "cat[1-9]".

        Added option "--cmake" to search for matches along the built-in Cmake
        module path and '%CMAKE_MODULE_PATH%'.

  0.99: Option "--pe" now calls WinTrust functions (in win_trust.c) to check if
        a PE-file is "Verified", "Not trusted" etc.

  1.0:  Added option "--pkg" to search in pkg-config's searcch-path specified by
        %PKG_CONFIG_PATH%.

  1.1:  Added option "--check" to check for missing directories in all supported
        environment variables.
        Added reading of an config-file; "%APPDATA%\envtool.cfg" is read at startup
        to support files to ignore. Copy the included "envtool.cfg" to your "%APPDATA"
        folder if needed.

  1.2:  Modifiers for "--evry" option is now possible. E.g.
          envtool --evry *.exe rc:today                     - find today's changes of all *.exe files.
          envtool --evry Makefile.am content:pod2man        - find Makefile.am with pod2man commands.
          envtool --evry M*.mp3 artist:Madonna "year:<2002" - find all Madonna M*.mp3 titles issued prior to 2002.
