Is it possible in PowerShell, to truncate a string, (using SubString()
?), to a given maximum number of characters, even if the original string is already shorter?
For example:
foreach ($str in "hello", "good morning", "hi") { $str.subString(0, 4) }
The truncation is working for hello
and good morning
, but I get an error for hi
.
I would like the following result:
hell
good
hi
You need to evaluate the current item and get the length of it. If the length is less than 4 then use that in the substring function.
foreach ($str in "hello", "good morning", "hi") {
$str.subString(0, [System.Math]::Min(4, $str.Length))
}
