When I enter "ri" the powershell thinks it is "Remove-Item" - how do I use the ri command to invoke the "R"uby "I"ndex?
After poking around SO: ruby 1.9 ri on Windows knows nothing about any classes I tried cd'ing to the C:\Ruby22 and entering:
rdoc --all --ri
gem install rdoc rdoc-data
I entered this in Powershell's command line prompt:
rm -Force alias:ri
to get rid of the (ri = Remove-Item) association.
Now I can delete the duplicate files I named
C:\Ruby22\bin\rr & rr.bat and having set-up the Ruby Index with the above commands, Powershell recognizes "ri" as the command for Ruby Index. Yay.
Pardon my ignorance of shell conventions, but I found this resource useful: http://powershell.com/cs/blogs/tips/archive/2009/04/16/deleting-aliases.aspx
...and lastly, the other "remove" commands still work just fine: Remove-Item, remove-item, rm, rmdir, rd...
