[ ]`\r\n\r\n`Remove-Item` and `Move-Item` currently do not support that, neither with `-Path` nor with `-Include`.\r\n\r\nSteps to reproduce\r\n------------------\r\n\r\n```powershell\r\n# Create a file that contains a literal backtick and a literal substring that would be a valid\r\n# sub-pattern if interpreted as a wildcard expression.\r\nNew-Item -Type File 'a`[b]'\r\n\r\n# Match the newly created file using a wildcard expression with suitable escaping.\r\nRemove-Item * -Include 'a```[b`]'  -WhatIf\r\nRemove-Item -Path 'a```[b`]' -WhatIf\r\n\r\nMove-Item * -Include 'a```[b`]' /tmp -WhatIf\r\nMove-Item -Path 'a```[b`]' /tmp -WhatIf\r\n```\r\n\r\nExpected behavior\r\n-----------------\r\n\r\nBoth commands in each pair should find the target file and output information about how it _would_ be deleted / moved.\r\n\r\nActual behavior\r\n---------------\r\n\r\nAll commands unexpectedly fail to find the file:\r\n\r\n```\r\nRemove-Item : An object at the specified path /Users/jdoe/a`[b] does not exist.\r\n...\r\n```\r\nCuriously, the error message quotes the correct _literal_ path that it claims doesn't exist.\r\n\r\n`Move-Item`'s symptoms differ: \r\n\r\n```\r\nMove-Item : Cannot move item because the item at '...' does not exist.\r\n...\r\nMove-Item : The specified wildcard character pattern is not valid: a\\[b\r\n```\r\n\r\nCuriously, all existing files in the directory (even those that don't match the pattern) are reported as non-existent.\r\n\r\nEnvironment data\r\n----------------\r\n\r\n```powershell\r\nPowerShell Core v6.0.0-alpha (v6.0.0-alpha.18) on macOS 10.12.4\r\nPowerShell Core v6.0.0-alpha (v6.0.0-alpha.18) on Ubuntu 16.04\r\n```\r\n","author":{"url":"https://github.com/mklement0","@type":"Person","name":"mklement0"},"datePublished":"2017-05-07T19:52:41.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/3725/PowerShell/issues/3725"}
