String split in windows powershell

Question

Can you please help me to get the desired output, where SIT is the environment and type of file is properties, i need to remove the environment and the extension of the string.

#$string="<ENV>.<can have multiple period>.properties
*$string ="SIT.com.local.test.stack.properties"
$b=$string.split('.')
$b[0].Substring(1)*

Required output : com.local.test.stack //can have multiple period

Answer 1

This should do.

$string = "SIT.com.local.test.stack.properties"
# capture anything up to the first period, and in between first and last period
if($string -match '^(.+?)\.(.+)\.properties$') {
 $environment = $Matches[1]
 $properties = $Matches[2]
 # ... 
}

Answer 2

You may use

$string -replace '^[^.]+\.|\.[^.]+$'

This will remove the first 1+ chars other than a dot and then a dot, and the last dot followed with any 1+ non-dot chars.

See the regex demo and the regex graph:

enter image description here

Details

• ^ - start of string
• [^.]+ - 1+ chars other than .
• \. - a dot
• | - or
• \. - a dot
• [^.]+ - 1+ chars other than .
• $ - end of string.

Answer 3

You can use -match to capture your desired output using regex

$string ="SIT.com.local.test.stack.properties"
$string -match "^.*?\.(.+)\.[^.]+$"
$Matches.1

Answer 4

You can do this with the Split operator also.

($string -split "\.",2)[1]

Explanation:

You split on the literal . character with regex \.. The ,2 syntax tells PowerShell to return 2 substrings after the split. The [1] index selects the second element of the returned array. [0] is the first substring (SIT in this case).
