I am unable to do: `cd somewhere ; cvs update`

because it doesn’t like the cd, and possibly not the ;. I also get a  
strange  
blowup when I do:

```
		`cvs update somewhere`

```

where it says: Protocol error: ’  
Protocol error: ‘Directory’ missingE Protocol error: ‘Directory’  
missingE

and on and on…

Can you please suggest something. I need to make this work, and I’m not  
finding it obvious in any way.

Off the top of my head: User full paths for the cvs binary and the  
target file or directory

Dir.chdir, preferably with a block.  
e.g:  
irb(main):001:0\> Dir.pwd  
=\> “/Users/logan/Projects/Ruby Experiments”  
irb(main):002:0\> Dir.chdir("/") { puts Dir.pwd; `ls` }  
/  
=\> “Applications\nApplications (Mac OS 9)\nDesktop DB\nDesktop DF  
\nDesktop Folder\nDeveloper\nLibrary\nNetwork\nPrevious Systems  
\nSystem\nSystem Folder\nTheVolumeSettingsFolder\nUser Guides And  
Information\nUsers\nVolumes\nautomount\nbin\ncores\ndev\netc\nmach  
\nmach.sym\nmach\_kernel\nprivate\nsbin\nsw\ntmp\nusr\nvar\n”  
irb(main):003:0\> Dir.pwd  
=\> “/Users/logan/Projects/Ruby Experiments”

So in your case you would use:  
cvs\_output = Dir.chdir(“somewhere”) { `cvs update` }
