説明

    The `Select-String` cmdlet uses regular expression matching to search for text patterns in input strings and files. You can use `Select-String

    ` similar to `grep` in UNIX or `findstr.exe` in Windows.

    `Select-String` is based on lines of text. By default, `Select-String` finds the first match in each line and, for each match, it displays the

     file name, line number, and all text in the line containing the match. You can direct `Select-String` to find multiple matches per line, disp

    lay text before and after the match, or display a Boolean value (True or False) that indicates whether a match is found.

    `Select-String` can display all the text matches or stop after the first match in each input file. `Select-String` can be used to display all

    text that doesn't match the specified pattern.

    You can also specify that `Select-String` should expect a particular character encoding, such as when you're searching files of Unicode text.

    `Select-String` uses the byte-order-mark (BOM) to detect the encoding format of the file. If the file has no BOM, it assumes the encoding is U

    TF8.
