%path%looks something like this:
PATH=c:rubybin;C:Perlsitebin;C:Perlbin;C:Oracle OraHome817bin;C:oracleproduct10.2.0gpdbin;C:Program FilesOraclejre1.1.7bin;C:Python26;C:Python26scripts;C: Python26Libidlelib;C:cygwinbin;C:Program FilesWindows Resource KitsTools;C:WINDOWSsystem32;C:WINDOWS;C:WINDOWS Downloaded ProgramFiles;C:Program FilesIBMDirectorbin;C: Program FilesDiskeeper CorporationDiskeeper;c:Program FilesMicrosoft SQL Server90Toolsbinn;C:Program Files Rationalcommon;c:scripts;C:Program FilesjEdit;C:Program FilesQuickTimeQTSystem;C:Program FilesTortoiseSVNbin;C: ipdsdevaxis2axis2c-rel-1.3.0lib;C:Program FilesJava jdk1.5.0_16bin;C:jruby-1.2.0bin
Then save this to "road.bat" somewhere on your path:
@echo off rem source: http://www.perlmonks.org/?node_id=757655 for %%i in ("%path:;=" "%") do @echo %%i
When you run
C:\>roadall those paths are nicely split and one-lined:
C:>road "c:rubybin" "C:Perlsitebin" "C:Perlbin" "C:OracleOraHome817bin" "C:oracleproduct10.2.0gpdbin" ...
and you can do cool things like
C:\>road | find /i "Perl"to find out where Perl is hiding.
To paraphrase the (brilliant) author VinsWorldcom, this one-liner
wraps the %PATH% ENV var in double quotes and then replaces all the semicolon separators with a double-quote, space, double quote. This effectively puts double quotes around all the paths (so spaces won't give any troubles) then use the for loop to list each newly double-quoted string.
