This article describes the string substitution operator in PowerShell: Replace. In Replace, you can use regular expressions, which greatly improves the functionality of replace.
Copy Code code as follows:
Ps> ' unit1,unit2,unit3 '-replace ' [, T] ', '; '
Unit1; Unit2; Unit3
The above example uses a comma (,) or tab (\ t) from the given string to replace the component number (;). This is a very common application that is often needed to construct a CSV file. A CSV file is a semicolon-delimited data for each cell.
The use of the replace operator is:
Copy Code code as follows:
< pending strings >-replace < find character >,< replacement character >
Explain the meaning of this grammar, which is to find the < lookup character in the < pending string >, and replace the < lookup character > with the < replacement character >. Here,< find characters > You can use regular expressions. Finding a match through a regular expression will greatly enhance the function of the replace operator.
