Extract a certain file from an archive with 7-Zip from the command line



7-Zip is a popular and free open source file archiving program used to compress and decompress files. It is available as a command line tool and a GUI tool, both of which support a wide range of archive formats. With 7-Zip, IT administrators can easily extract a certain file from an archive from the command line.

To extract a certain file from an archive with 7-Zip from the command line, the administrator will need to use the “x” (extract) command. This command supports a wide range of archive formats including 7z, ZIP, RAR, CAB, ISO, and others. The administrator can then specify the source archive and the destination folder to extract the files to.

The syntax for the extract command is as follows:

7z x [source archive] -o[destination folder] [file(s) to extract]

The source archive is the full path and filename of the archive containing the file(s) to be extracted. The destination folder is the path to the folder where the files will be extracted. The file(s) to extract is the name of the file or files to be extracted. The file(s) can be a wildcard to extract all files from the archive.

For example, if an administrator wants to extract the file “example.txt” from the archive “C:\\Data\\Archive.zip” to the folder “C:\\Data\\Extracted”, the command would be as follows:

7z x C:\\Data\\Archive.zip -oC:\\Data\\Extracted example.txt

The administrator can also extract multiple files from the archive at once. For example, if an administrator wants to extract the files “example.txt” and “example2.txt” from the archive “C:\\Data\\Archive.zip” to the folder “C:\\Data\\Extracted”, the command would be as follows:

7z x C:\\Data\\Archive.zip -oC:\\Data\\Extracted example.txt example2.txt

The administrator can also extract all files from the archive. To do this, the administrator can use a wildcard as the file(s) to extract. For example, if an administrator wants to extract all files from the archive “C:\\Data\\Archive.zip” to the folder “C:\\Data\\Extracted”, the command would be as follows:

7z x C:\\Data\\Archive.zip -oC:\\Data\\Extracted *

These commands can be used for a wide range of archive formats. For more information about the 7-Zip command line syntax and options, the administrator can refer to the 7-Zip documentation.

Using the 7-Zip command line tool, IT administrators can easily extract a certain file from an archive from the command line. This can save the administrators time and effort when dealing with large archives. The syntax is simple and the tool is powerful, allowing the administrator to extract multiple files or all files from an archive with ease.
