powershell escape double quote is the technique to include double-quote characters within PowerShell string literals using the backtick (`) escape character, doubling quotes, or here-strings.
"Text with `"embedded double quote`" and escaped `$variable"Syntax
# Escape within double-quoted string (variable expansion enabled)
"Text with `"embedded double quote`" and escaped `$variable"
# Escape within single-quoted string (no expansion)
'Text with ''embedded single quote'' or "double quote"'
# Here-string (double-quoted variant)
@"
Line with "double quotes" without escaping
"@
# Escape smart quotation marks (Unicode)
"Double `“smart quotes`” escaped with backtick"
Tested on Windows Server 2022 with PowerShell 7.4 and Windows PowerShell 5.1.
Options and Flags
| Escape Method | Scope | Example | Notes |
|---|---|---|---|
| Backtick (`) | Double-quoted strings | "`"Hello`"" |
Escape character for double quote, dollar sign, and other special chars. Works in PS 2.0+. |
| Double quote | Double- or single-quoted strings | ""Hello"",''Hello'' |
Replace each embedded quote with two consecutive quotes. Universal across versions. |
| Here-string | Multi-line text | @" ... "@ or @' ... '@ |
No escaping needed for quotes inside. Double-quoted variant expands variables; single-quoted does not. |
Usage Examples
1. Embedding double quotes inside a double-quoted string with variable expansion
$name = "World"
$message = "Hello, `"$name`"! The path is `"C:Program Files`"."
Write-Host $message
# Output: Hello, "World"! The path is "C:Program Files.
Each backtick before a double quote prevents the quote from closing the string. The variable $name is still expanded. The backtick also escapes the backslash before the final quote.
2. Using doubled quotes to include a single double quote
$string = "He said ""PowerShell is powerful"""
Write-Host $string
# Output: He said "PowerShell is powerful"
Two consecutive double quotes ("""") inside a double-quoted string produce one literal double quote. This method is often more readable than backtick escapes.
3. Passing a quoted argument to an external executable
$arg = 'C:Program FilesMyAppfile.txt'
# Need to pass a quoted path to cmd.exe
cmd /c "echo The file is `"$arg`""
# Output: The file is "C:Program FilesMyAppfile.txt"
When PowerShell passes strings to external programs, additional escaping may be required. Using backslash+backtick (`) ensures the double quote is forwarded correctly to cmd.exe.
Troubleshooting & Common Errors
| Error Message | Root Cause | Resolution |
|---|---|---|
The string is missing the terminator: " |
Unclosed double-quoted string after a backtick escape that was misapplied | Verify each opening quote has a matching closing quote; ensure backtick is not escaping the closing quote itself. |
Cannot convert value to type "System.String" |
Smart quotation marks (U+201C/U+201D) used instead of ASCII quotes | Replace with standard double quotes or escape using `" for smart quotes inside a double-quoted string. |
Unexpected token '""' in expression or statement |
Double quotes used in a context where two consecutive quotes are mistaken for an empty string operator | Use a single backtick escape (`") or a different quoting method. |
| External command receives wrong argument | PowerShell may strip or add extra quotes when passing arguments; the backslash before backtick is missing | Use `" or the --% stop-parsing symbol for arguments. |
Frequently Asked Questions
What is the difference between using backtick (`) and doubling double quotes (“”) to escape a double quote in PowerShell?
Answer: Backtick escapes a double quote within double-quoted strings; doubling escapes quotes within expandable strings but only for literal quote. Backtick is the escape character used in double-quoted strings to insert a literal double quote: Write-Host "He said `"Hello`"". Doubling a double quote (“””) is used inside double-quoted strings to represent one literal double quote: Write-Host "He said ""Hello""". Both produce identical output. Use backtick for readability or when inside expandable strings; use doubling for compatibility with older argument parsers (e.g., passing to external commands).
When should I use the `–%` (stop-parsing) symbol to escape double quotes for external commands?
Answer: Use `–%` when passing arguments containing double quotes to native executables. After `–%`, PowerShell treats the rest of the argument string literally, preserving double quotes for the target command. Example: cmd /c --% echo "quoted string". Without `–%`, PowerShell strips outer quotes. Use `–%` for complex native command strings that include spaces and double quotes, avoiding manual backtick escaping.
How do I fix the error “Unexpected token ‘””‘ in expression or statement” when escaping double quotes in a PowerShell string?
Answer: Replace explicit double quotes inside expandable strings with backtick-escaped quotes (`”) or use single-quote strings (‘) that treat double quotes as literals. The error occurs when PowerShell encounters an unescaped double quote inside a double-quoted string. Fix by escaping: $path = "C:Path`"File`".txt". Alternatively, switch to a single-quoted string: $path = 'C:Path"File".txt'. When building strings with variables, use subexpression $() inside double quotes and escape only the needed double quotes.
Does the backtick (`) escape method for double quotes work identically on PowerShell Core (Linux/macOS) as on Windows PowerShell?
Answer: Yes, the backtick escape character behaves identically across all PowerShell platforms (Windows, Linux, macOS) for escaping double quotes. PowerShell Core (v6+) uses the same escaping rules as Windows PowerShell 5.1. Example on Linux: Write-Host "It`"s working" produces It"s working. However, note that the backtick character is also the line continuation character. For platform-specific quirks, avoid mixing with Unix shell quoting; always rely on PowerShell’s parser alone.
What is the fastest way to escape a double quote in a PowerShell command passed to a subprocess (e.g., Start-Process or Invoke-Expression)?
Answer: Use the `–%` stop-parsing symbol for native commands; for cmdlets, wrap the argument string in single quotes and use double quotes only inside. For native executables, stop-parsing is fastest: Start-Process cmd -ArgumentList '/c --% echo "quoted"'. For PowerShell cmdlets, embed double quotes inside a single-quoted argument: Invoke-Expression -Command 'Write-Host "escaped"'.
