Command Line

This is all implemented and working as of the v1.1.0 release (March 2013).

Use Cases

  • open file in GUI via command line
  • specify path to extract all files
  • Specify file(s) to extract (issue 23)
  • output msi version
  • output msi table to csv (patch in issue 26)

Syntax

lessmsi <command> [switches] <msi_name> [<path_to_extract\>] [file_names]

Note: If no command is specified the GUI opens.

Commands

Command o: - Open in GUI

Opens the specified msi_name in the GUI.

  • switches: Not supported.
  • msi_name: The name of the msi to open in the GUI
  • path_to_extract: Not supported.
  • file_names: Not supported.

Examples

lessmsi o theinstall.msi

Command x: - Extract

Extracts from the specified archive.

  • switches: Not supported.
  • msi_name: (required) specifies the msi to extract files from
  • path_to_extract: (optional) The path to extract the files to. MUST have trailing backslash or it will be treated as one of the file_names.
  • file_names: (optional) Names of files that you want to extract from the msi. All files are extracted if not specified.

Note: There is a known bug err "limitation" that you can only specify the name of the file (not the path). Therefore if there are multiple instances of the file inside the msi with the same name and you want to extract that file there is no way to specify which file to extract. If this is a problem for you report an issue and if I know it is important to someone I'll take the time to make that work.

Note: /x will work as the "command" for backward compatibility. The /x command is obsolete. It may be removed in the future!

Examples

Extracts all files from theinstall.msi into the current directory:

lessmsi x theinstall.msi

Extracts a.txt and b.txt from c:\theinstall.msi into the directory c:\theinstallextracted.

lessmsi x c:\theinstall.msi c:\theinstallextracted\ a.txt b.txt
