名前 Set-Content 概要 Writes or replaces the content in an item with new content. 構文 Set-Content [-Path] [-Value] [-Credential []] [-Encoding {Unknown | Stri ng | Unicode | Byte | BigEndianUnicode | UTF8 | UTF7 | UTF32 | Ascii | Default | Oem | BigEndianUTF32}] [-Ex clude []] [-Filter []] [-Force] [-Include []] [-NoNewline] [-PassThru] [-Stream []] [-Confirm] [-WhatIf] [-UseTransaction []] [] Set-Content [-Value] [-Credential []] [-Encoding {Unknown | String | Unicode | Byte | BigEndianUnicode | UTF8 | UTF7 | UTF32 | Ascii | Default | Oem | BigEndianUTF32}] [-Exclude []] [-Filter []] [-Force] [-Include []] [-NoNewline] [-PassThru] [-Stream []] -Litera lPath [-Confirm] [-WhatIf] [-UseTransaction []] [] 説明 The Set-Content cmdlet is a string-processing cmdlet that writes or replaces the content in the specified it em, such as a file. Whereas the Add-Content cmdlet appends content to a file, Set-Content replaces the exist ing content. You can type the content in the command or send content through the pipeline to Set-Content. パラメーター -Credential [] Specifies a user account that has permission to perform this action. The default is the current user. Type a user name, such as User01 or Domain01\User01, or enter a PSCredential object, such as one generat ed by the Get-Credential cmdlet. If you type a user name, you will be prompted for a password. This parameter is not supported by any providers installed with Windows PowerShell. 必須 false 位置 named 既定値 none パイプライン入力を許可する true (ByPropertyName) ワイルドカード文字を許可する false -Encoding [] Specifies the file encoding. The acceptable values for this parameter are: -- ASCII. Uses the encoding for the ASCII (7-bit) character set. -- BigEndianUnicode. Encodes in UTF-16 format using the big-endian byte order. -- Byte. Encodes a set of characters into a sequence of bytes. -- String. Uses the encoding type for a string. -- Unicode. Encodes in UTF-16 format using the little-endian byte order. -- UTF7. Encodes in UTF-7 format. -- UTF8. Encodes in UTF-8 format. -- Unknown.: The encoding type is unknown or invalid. The data can be treated as binary. The default value is ASCII. Encoding is a dynamic parameter that the FileSystem provider adds to Set-Content. This parameter works o nly in file system drives. 必須 false 位置 named 既定値 none パイプライン入力を許可する false ワイルドカード文字を許可する false -Exclude [] Specifies items that this cmdlet omits. The value of this parameter qualifies the Path parameter. Enter a path element or pattern, such as *.txt. Wildcard characters are permitted. 必須 false 位置 named 既定値 none パイプライン入力を許可する false ワイルドカード文字を許可する false -Filter [] Specifies a filter in the format or language of the provider. The value of this parameter qualifies the Path parameter. The syntax of the filter, including the use of wildcard characters, depends on the provi der. Filters are more efficient than other parameters, because the provider applies them when it is retr ieving the objects, instead of having Windows PowerShell filter the objects after they are retrieved. 必須 false 位置 named 既定値 none パイプライン入力を許可する false ワイルドカード文字を許可する false -Force [] Forces the cmdlet to set the contents of a file, even if the file is read-only. Implementation varies fr om provider to provider. For more information, see about_Providers. Even using the Force parameter, the cmdlet cannot override security restrictions. 必須 false 位置 named 既定値 none パイプライン入力を許可する false ワイルドカード文字を許可する false -Include [] Specifies items that this cmdlet changes. The value of this parameter qualifies the Path parameter. Ente r a path element or pattern, such as *.txt. Wildcard characters are permitted. 必須 false 位置 named 既定値 none パイプライン入力を許可する false ワイルドカード文字を許可する false -LiteralPath Specifies the path of the item that receives the content. Unlike Path, the value of the LiteralPath para meter is used exactly as it is typed. No characters are interpreted as wildcard characters. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell Windows Po werShell not to interpret any characters as escape sequences. 必須 true 位置 named 既定値 none パイプライン入力を許可する true(ByPropertyName) ワイルドカード文字を許可する false -NoNewline [] Indicates that this cmdlet uses the no newline setting. 必須 false 位置 named 既定値 none パイプライン入力を許可する false ワイルドカード文字を許可する false -PassThru [] Returns an object that represents the content. By default, this cmdlet does not generate any output. 必須 false 位置 named 既定値 none パイプライン入力を許可する false ワイルドカード文字を許可する false -Path Specifies the path of the item that receives the content. Wildcard characters are permitted. 必須 true 位置 1 既定値 none パイプライン入力を許可する true (ByPropertyName) ワイルドカード文字を許可する false -Stream [] Specifies an alternative data stream for content. If the stream does not exist, this cmdlet creates it. Wildcard characters are not supported. Stream is a dynamic parameter that the FileSystem provider adds to Set-Content. This parameter works onl y in file system drives. You can use the Set-Content cmdlet to change the content of the Zone.Identifier alternate data stream. H owever, we do not recommend this as a way to eliminate security checks that block files that are downloa ded from the Internet. If you verify that a downloaded file is safe, use the Unblock-File cmdlet. This parameter was introduced in Windows PowerShell 3.0. 必須 false 位置 named 既定値 none パイプライン入力を許可する false ワイルドカード文字を許可する false -Value Specifies the new content for the item. 必須 true 位置 2 既定値 none パイプライン入力を許可する true (ByValue, ByPropertyName) ワイルドカード文字を許可する false -Confirm [] Prompts you for confirmation before running the cmdlet.Prompts you for confirmation before running the c mdlet. 必須 false 位置 named 既定値 false パイプライン入力を許可する false ワイルドカード文字を許可する false -WhatIf [] Shows what would happen if the cmdlet runs. The cmdlet is not run.Shows what would happen if the cmdlet runs. The cmdlet is not run. 必須 false 位置 named 既定値 false パイプライン入力を許可する false ワイルドカード文字を許可する false -UseTransaction [] Includes the command in the active transaction. This parameter is valid only when a transaction is in pr ogress. For more information, seeIncludes the command in the active transaction. This parameter is vali d only when a transaction is in progress. For more information, see 必須 false 位置 named 既定値 false パイプライン入力を許可する false ワイルドカード文字を許可する false このコマンドレットは、次の共通パラメーターをサポートします: Verbose、 Debug、ErrorAction、ErrorVariable、WarningAction、WarningVariable、 OutBuffer, PipelineVariable、および OutVariable。詳細については、 about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216) を参照してください。 入力 System.Object You can pipe an object that contains the new value for the item to this cmdlet. 出力 None, System.String This cmdlet generates a System.String object that represents the content, if you specify the Passthru pa rameter. Otherwise, this cmdlet does not generate any output. メモ You can also refer to Set-Content by its built-in alias, sc. For more information, see about_Aliases. Set-Content is designed for string processing. If you pipe non-string objects to this cmdlet, it convert s the object to a string before writing it. To write objects to files, use Out-File. Set-Content cmdlet is designed to work with the data exposed by any provider. To list the providers avai lable in your session, type Get-PsProvider. For more information, see about_Providers. Example 1: Replace the contents of multiple files in a folder PS C:\>Set-Content -Path "C:\Test1\test*.txt" -Value "Hello, World" This command replaces the contents of all files in the Test1 folder that have names that start with "test" w ith "Hello, World". This example shows how to specify content by typing it in the command. Example 2: Send content to a file PS C:\>Get-Date | Set-Content -Path "C:\Test1\date.csv" This command creates a comma separated variable length (csv) file that contains only the current date and ti me. It uses the Get-Date cmdlet to get the current system date and time. The pipeline operator passes the re sult to Set-Content, which creates the file and writes the content. If the Test1 directory does not exist, the command fails, but if the file does not exist, the command create s it. Example 3: Replace text in a file PS C:\>(Get-Content -Path "Notice.txt") | ForEach-Object {$_ -Replace "Warning", "Caution"} | Set-Content -P ath "Notice.txt" This command replaces all instances of Warning with Caution in the Notice.txt file. It uses Get-Content to get the content of Notice.txt. The pipeline operator sends the results to the ForEach -Object cmdlet, which applies the expression to each line of content in Get-Content. The expression uses the $_ symbol to refer to the current item and the Replace parameter to specify the text to be replaced. Another pipeline operator sends the changed content to Set-Content which replaces the text in Notice.txt wit h the new content. The parentheses around Get-Content make sure that the Get operation is complete before the Set operation sta rts. Without them, the command fails because the two functions will be trying to access the same file. 関連するリンク Online Version: http://go.microsoft.com/fwlink/p/?linkid=293909 Add-Content Clear-Content Get-Content
