replace foo -> bar in all .txt files down the tree

Dunno why, the syntax highlighter adds 3's to the code. Try plain text.

# Select files
$files = gci . -recurse | ? { ($_ -match "txt$") -and ((gc $_.VersionInfo.FileName) -match "the_sink") } | % { $_.VersionInfo.FileName }
 
# Back'em up, just in case:
$files | % { cp $_ "$($_).bak" }
 
# Replace
$files | %{ (gc $_) -replace "foo","bar" | sc -Path $_ }
