That returns a very large number, but does not guarantee all lines if the file has more lines than `$([int]::MaxValue)`.\r\n\r\n### Expected behavior\r\n\r\n```console\r\nPS\u003e Get-Content ${filePath} -Wait -Tail -1\r\n\u003cfull content of the file at ${filePath} shown here\u003e\r\n```\r\n\r\n\r\n### Observed behavior\r\n\r\n```console\r\nPS\u003e Get-Content ${filePath} -Wait -Tail -1\r\nGet-Content: Cannot validate argument on parameter 'Tail'. The -1 argument is less than the minimum allowed range of 0. Supply an argument that is greater than or equal to 0 and then try the command again.\r\n```\r\n\r\n\r\n### Error details\r\n\r\nI am submitting this issue report on a different computer from the one in which I discovered this issue, so I don't have direct copy access to the output of `Get-Error`.  The error says `Get-Content: Cannot validate argument on parameter 'Tail'. The -1 argument is less than the minimum allowed range of 0. Supply an argument that is greater than or equal to 0 and then try the command again.` though.\r\n\r\n\r\n### Environment data\r\n\r\nI am submitting this issue report on a different computer from the one in which I discovered this issue, so I don't have direct copy access to the output of ${PSVersionTable}.  It says the version is `7.4.1` though.","author":{"url":"https://github.com/BujuArena","@type":"Person","name":"BujuArena"},"datePublished":"2024-03-15T19:27:16.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/21347/PowerShell/issues/21347"}
