在PowerShell中转义单引号

Question

I have a replace statement in my code whereby Band's is being replaced by Cig's. However when I put single quote it took the first sentence... Example 'Band'

I tried to use double quote but it does not work. Do you know how to escape the single quote sign?

-replace 'Band's', 'Cig's'

Answer 1

See Escape characters, Delimiters and Quotes and Get-Help about_Quoting_Rules from the built-in help (as pointed out by as Nacimota).

To include a ' inside a single-quoted string, simply double it up as '' . (Single-quote literals don't support any of the other escape characters.)

> "Band's Toothpaste" -replace 'Band''s', 'Cig''s'

Or, simply switch to double-quotes. (Double-quote literals are required when wishing to use interpolation or escape characters.)

> "Band's Toothpaste" -replace "Band's", "Cig's"

(Don't forget that -replace uses a regular expression )

Answer 2

Escape a single quote with two single quotes:

"Band's Toothpaste" -replace 'Band''s', 'Cig''s'

Also, this is a duplicate of Can I use a single quote in a Powershell 'string'?

Answer 3

For trivial cases, you can use embedded escape characters. For more complex cases, you can use here-strings.

$Find = [regex]::escape(@'
Band's
'@)

$Replace = @'
Cig's
'@

"Band's Toothpaste" -replace $Find,$Replace

Then put the literal text you want to search for and replace in the here-strings.

Normal quoting rules don't apply within the here-string @' - '@ delimiters, so you can put whatever kind of quotes you want, wherever you want them without needing any escape characters.

The [regex]::excape() on $Find will take care of doing the backslash escapes on any regex reserved characters that might be in the search pattern.
