Get-Content -Raw neglects to read the last character, if it is a LF #4980
Description
Steps to reproduce
Save the following to t.Tests.ps1 and invoke with ./t.Tests.ps1:
Describe "Get-Content -Raw test" {
BeforeAll {
Push-Location TestDrive:/
$lfTextUnterminated = "a`nb"
$lfText = "a`nb`n"
$crlfTextUnterminated = "a`r`nb"
$crlfText = "a`r`nb`r`n"
Set-Content -Encoding Ascii -NoNewline 'lf.txt' -value $lfText
Set-Content -Encoding Ascii -NoNewline 'crlf.txt' -value $crlfText
Set-Content -Encoding Ascii -NoNewline 'lf-nt.txt' -value $lfTextUnterminated
Set-Content -Encoding Ascii -NoNewline 'crlf-nt.txt' -value $crlfTextUnterminated
}
It "Reads LF-terminated files in full." {
Get-Content -Raw 'lf.txt' | Should BeExactly $lfText
}
It "Reads CRLF-terminated files in full." {
Get-Content -Raw 'crlf.txt' | Should BeExactly $crlfText
}
It "Reads LF-separated files without trailing newline in full." {
Get-Content -Raw 'lf-nt.txt' | Should BeExactly $lfTextUnterminated
}
It "Reads CRLF-separated files without trailing newline in full." {
Get-Content -Raw 'crlf-nt.txt' | Should BeExactly $crlfTextUnterminated
}
AfterAll {
Remove-Item -LiteralPath 'lf.txt', 'lf-nt.txt', 'crlf.txt', 'crlf-nt.txt'
Pop-Location
}
}Expected behavior
All tests should pass.
Actual behavior
The files ending in an LF character are read without that last character.
Note that Windows Powershell is not affected.
