Этот скрипт Powershell переименует файлы так, как вам нужно. Сохраните его как RenameFiles.ps1 и запустите из консоли PowerShell.
Скрипт принимает следующие аргументы:
- Путь: Обязательно, существующая папка на диске, где хранятся ваши файлы.Вы можете указать несколько путей.
- Recurse: опциональный переключатель, контролирует рекурсию.Если указано, скрипт будет переименовывать файлы во всех подпапках.
- WhatIf: Необязательный переключатель, если он указан, скрипт будет сообщать только о новых и старых именах файлов.Переименование не будет сделано.
Примеры (запускаются из консоли PowerShell):
Переименуйте все файлы в папке c:\path\to\files:
.\RenameFiles.ps1 -Path 'c:\path\to\files'
Переименуйте все pdf файлы в папке c:\path\to\files:
.\RenameFiles.ps1 -Path 'c:\path\to\files\*.pdf'
Переименуйте все pdf файлы в папке c:\path\to\files , recurse
.\RenameFiles.ps1 -Path 'c:\path\to\files\*.pdf' -Recurse
Сканирование файлов в нескольких папках, повтор, только отчет (без переименования):
.\RenameFiles.ps1 -Path 'c:\path\A\*.pdf', 'c:\path\B\*.psd' -Recurse -WhatIf

Begin

# You can change this block to adapt new rules for file renaming,
# without modifying other parts of script.
# Regex to match, capture groups are used to build new file name
$Regex = '(Sample2).*(\d{2}-\d{2}-\d{4}).*(?<=[a-z]_)(\d+)(?=_\d+).*(?<=_)(\d+)$'
# Scriptblock that builds new file name. $Matches is hashtable, but we need array for the format (-f) operator.
# So this code: @(0..$Matches.Count | ForEach-Object {$Matches[$_]})} transforms it to the array.
# Basically, we creating a new array of integers from 0 to count of $Matches keys, e.g. @(0,1,2,3,4,5)
# and passing it down the pipeline. Then, in the foreach loop we output values of $Matches keys which name
# match the current pipeline object, e.g. $Matches['1'], $Matches['2'], etc.
# $Matches['0'] holds whole matched string, other keys hold capture groups.
# This would also work:
# $NewFileName = {'{0}_{1}_{2}_{3}{4}' -f $Matches['1'], $Matches['2'], $Matches['3'], $Matches['4'], $Matches['5']
$NewFileName = {'{1}_{2}_{3}_{4}{5}' -f @(0..$Matches.Count | ForEach-Object {$Matches[$_]})}
}

# If original file name matches regex
if($FileName -match $Regex)

В этом сценарии используется регулярное выражение: https://regex101.com/r/hT2uN9/2 (обратите внимание, что регулярное выражение PowerShell по умолчанию не учитывает регистр). Копия объяснения регулярного выражения здесь:
Регулярное выражение:
(Sample2).*(\d{2}-\d{2}-\d{4}).*(?<=[a-z]_)(\d+)(?=_\d+).*(?<=_)(\d+)$
Строка Sample2 :
1st Capturing group (Sample2)
Sample2 matches the characters Sample2 literally (case insensitive)
Любой символ (не захвачен и не существует в переменной $Matches ):
.* matches any character (except newline)
Quantifier: * Between zero and unlimited times, as many times as possible,
giving back as needed [greedy]
Дата:
2nd Capturing group (\d{2}-\d{2}-\d{4})
\d{2} match a digit [0-9]
Quantifier: {2} Exactly 2 times
- matches the character - literally
\d{2} match a digit [0-9]
Quantifier: {2} Exactly 2 times
- matches the character - literally
\d{4} match a digit [0-9]
Quantifier: {4} Exactly 4 times
Любой символ (не захвачен и не существует в переменной $Matches ):
.* matches any character (except newline)
Quantifier: * Between zero and unlimited times, as many times as possible,
giving back as needed [greedy]
Количество страниц:
(?<=[a-z]_) Positive Lookbehind - Assert that the regex below can be matched
[a-z] match a single character present in the list below
a-z a single character in the range between a and z (case insensitive)
_ matches the character _ literally
3rd Capturing group (\d+)
\d+ match a digit [0-9]
Quantifier: + Between one and unlimited times, as many times as possible,

(?=_\d+) Positive Lookahead - Assert that the regex below can be matched
_ matches the character _ literally
\d+ match a digit [0-9]
Quantifier: + Between one and unlimited times, as many times as possible,
