By default the PATH environment variable is searched (as well as, on Windows, the AppPaths key in the registry), but a specific 'path' list to search may be specified as well. On Windows, the PATHEXT environment variable is applied as appropriate. If "verbose" is true then a tuple of the form (, ) is returned for each match. The latter element is a textual description of where the match was found. For example: from PATH element 0 from HKLM\SOFTWARE\...\perl.exe i(tprint_functions Show the full path of commands. Usage: which [...] [...] Options: -h, --help Print this help and exit. -V, --version Print the version info and exit. -a, --all Print *all* matching paths. -v, --verbose Print out how matches were located and show near misses on stderr. -q, --quiet Just print out matches. I.e., do not print out near misses. -p , --path= An alternative path (list of directories) may be specified for searching. -e , --exts= Specify a list of extensions to consider instead of the usual list (';'-separate list, Windows only). Show the full path to the program that would be run for each given command name, if any. Which, like GNU's which, returns the number of failed arguments, or -1 when no was given. Near misses include duplicates, non-regular files and (on Un*x) files without executable access. s/$Id: which.py 430 2005-08-20 03:11:58Z trentm $iit.Nt WhichErrorcBseZRS((t__name__t __module__(((sB/home/psgendb/BIRCHDEV/install/weblogo-3.4/corebio/utils/_which.pyRQscCsd}tiidotii|didjo|d7}nddk}y3d|}|i |i |}|d|f}Wn|i j onX|o"tii |d o d}qn|S( sAWindows allow application paths to be registered in the registry.twinis.exeiNs4SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\s from HKLM\i( tNonetsystplatformt startswithtostpathtsplitexttlowert_winregt QueryValuetHKEY_LOCAL_MACHINEterrortexists(texeNamet registeredRtkeytvalue((sB/home/psgendb/BIRCHDEV/install/weblogo-3.4/corebio/utils/_which.pyt_getRegisteredExecutableXs# cCsetiido;tiitii|tiitii|jStii||SdS(NR(RRR R R tnormpathtnormcasetsamefile(tfname1tfname2((sB/home/psgendb/BIRCHDEV/install/weblogo-3.4/corebio/utils/_which.pyt _samefilejs cCsx|D]B}t|d|do$|otiid|ndSqWtiti|dip#|otiid|qnOti |dti p#|otiid|qn|i ||SdS(sCull inappropriate matches.
