In effect, Get-ChildItem looked for an file or directory named ls on all levels of the subdirectory hierarchy and, in the absence of any, produced no output, i.e. Ls in your dir -recurse ls command was positionally bound to Get-ChildItem'sīecause of the highly unfortunate behavior of -Path in combination with -Recurse, described in GitHub issue #5699, no error occurred, despite there (presumably) being no file or subdirectory literally named ls. This ran, but didn't do anything to any of the files If you want to match ALL only in all-uppercase, use the case- sensitive variant of the operator, Note: The -replace operator is case- insensitive by default, as PowerShell generally is. Also, omitting the replacement-string operand of the -replace operator defaults to '' (the empty string), so it can be omitted. I'm using '.' quoting instead of "." quoting for conceptual clarity, given that the string's content is to be used verbatim (no string interpolation needed). To see all aliases that are defined for Get-ChildItem, run Get-Alias -Definition Get-ChildItem.Īdditionally, to limit processing to files, add the -File switch: Get-ChildItem -File -Recurse | Rename-Item -NewName or, finally, using the full cmdlet name, Get-ChildItem -Recurse.or - the best choice if you want to use an alias - gci -recurse.Dir and ls are both aliases of PowerShell's Get-ChildItem cmdlet, so you need:
