PowerShell convert string / manipulation: substring etc.

PowerShell

In this article I show a few examples for manipulating strings (character strings)

.ToUpper()

Converts a string to uppercase letters

PS C:\> $("test").ToUpper()

Result:

TEST

.ToLower()

Converts a string into lowercase letters

PS C:\> $("TEST").ToLower()

Result:

test

.Contains()

Tests a string whether a certain string is present

PS C:\> $("TEST").Contains("ES")

Result:

True

.StartsWith()

Tests a string to see if it starts with a certain string.

PS C:\> $("TEST").StartsWith("TE")

Result:

True

.EndsWith()

Tests a string to see if it ends with a specific string.

PS C:\> $("TEST").EndsWith("ST")

Result:

True

.Replace()

Replaces a specified string within a string

PS C:\> $("TEST").Replace("TE","ersetzt")

Result:

ersetztST

.Substring()

Replaces parts of a string based on their position

PS C:\> $("TEST").Substring("1")

Result:

EST

here is another example: start and end position:

PS C:\> $("TEST").Substring("1","2")

Result:

ES

1 ... after the first character

2 ... up to the 2nd character

If only the end position should be used, it looks like this:

PS C:\> $("TEST").Substring("","3")

Result:

TES

.TrimStart()

Removes certain characters at the beginning of the string:

PS C:\> $("TEST").TrimStart("TE")

Result:

ST

^{({{pro_count}})}

Rate Post:
{{percentage}} % positive

^{({{con_count}})}
