Question

Using powershell I want to replace a specific numeric part of a string with another number.

It’s best to describe this problem with an example.

$s = '   First part: 65 Second Part'

###################################################################
# this generates "       First part: sixty-six Second Part"       #
###################################################################
$s -replace '^(\s*First part:\s+)[0-9]+(.*)$', '$1sixty-six$2'

###################################################################
# But I want to generate"    First part: 66 Second Part"          #
###################################################################
$s -replace '^(\s*First part:\s+)[0-9]+(.*)$', '$166$2'

It doesn’t work.

How do I specify “$1 followed by the number 66” as opposed to “$166”?

Answer 1

Use this syntax: ${1}66$2

Output:

'   First part: 66 Second Part'
