7-Zip Command-Line Examples

I have a server with about GB Files that i have to take backup twice a week. I have split these GB into 4 different backup jobs. After the backup i have a scheduled task. One of the files is about 12 GB and it takes a reasonable time to compress. But i have to transfer these files to the Cloud backup Solution. I need to add to this command a line that splits this file into pieces such as 1GB per file and also a number and date next to it so i know which file to look for on the cloud.

While using 7z there are two component as we can see in the syntax. One of them is commands. Commands are used to specify the operations like:. Switches are used to specify some minor options like create SFX archive, compress shared files, set output log level. Here are some of them. The new archive file name will be mybackup. Here the. Here while starting 7z applications shows some information about the 7z application like build number, version, developer. And than provided files and folders are scanned and the scan result is printed like 56 folders, files and total MB. After that the archive creation starts. Total items those will be compresses are show as Compression takes some time. In previous example we have created the archive file. Some time we need to add new files to the existing archive file. In this operation mybackup. Some information about the file is printed like path, compression type, size etc. Than new file is added to the existing archive or compressed file named mybackup. Another useful operation is removing one or more files from an existing archive file. In this example we want to remove file named fruits. As we can see from screenshot there are some existing files which will be over write. There question whether we want to over write, skip, rename etc. We answer this as Always. After extraction some statistical information like total folder count, file count size, compressed size is printed. We can also list files of an archive with l command. We will list all files of mybackup. In the output we can see that files and folders are listed.

Command Line Syntax


Skip to content. Skip to navigation. Although its interface is deceptively simple, the command-line versions of 7ZIP are highly customizable archiving programs when used with the command parameters and switches described below. Windows users who want to use the command-line version should generate a Help Desk ticket to install the standalone 7za. To begin a session, open a terminal window. Invoke the version of 7Zip you are using by entering " 7z " for P7Zip 7z. Please change the invocation to " 7za " when applying these examples for use in 7-Zip for Windows. The general command line syntax begins by invoking the version of 7Zip you are using:. Parameter and Switch Syntax: Use a separate -m switch for each parameter when adding them to the command line. The command-line versions of 7Zip look to the directory where the 7Zip executable file is located to find the files you are managing. Therefore, you will need to begin a session either by moving your files into 7Zip's directory or by using the full path for the file names. The full path must be enclosed in quotes as in the example above if any portion of it contains a space. Additionally, Windows users should use the Set Sensitive Case mode switch to " insensitive " -ssc. See Creating an Archive for detailed information on archive types. The archive type is denoted by the file type extension eg. If the archive doesn't exist, 7Zip will create it when you add the initial file s. Switches and other filenames can be in any order. Wildcards or filenames with spaces must be quoted:. Switch options can be combined to save command line length. However, some switch options take optional string arguments, and therefore must be the last option in a combined argument token string because 7-Zip accepts the rest of the argument token as the optional argument. Transferring files to recipients in other time zones, Daylight Savings Time adjustments and relocating notebook computers to different time zones can cause problems with update commands that depend on the file's modification time. However, in cases where you are restricted to using a file system that uses local time, use an archive format that supports local time as well; for example, use ZIP with FAT

These are the commands I am using:. All the files are compressed without their path. Is there a way to include the path for each file in the zip file? Then when backup. In this 7-zip forum threadin which many people express their desire for this feature, 7-zip's developer Igor points to the FAQ question titled "How can I store full path of file in archive? The command-line program for 7-Zip is 7z or 7za. Here's a helpful post on the options available. The -r recurse option stores paths. I've not looked into this but shooting from the hip I'd say that they dropped command line support in the portable. Typing that out for everything is why GUI's make sense with things like portable apps it the app can remember it's own location and handle that stuff for you and if you can't run it you know it's not attached. If you really want the portable app to contain that though you can always install the full version and pull the required 7z. It's not advisable to modify your system path for temproary "portable" drives though manualy do that by:. PS: sorry for the necro but I figured it needed a more direct answer to why even if it's just speculative. Since 7-zip version 9. If your list file has paths relative to another folder, you should be running 7Z from that folder. Update: I noticed from another post above that the new 7-Zip has an -spf option that doesn't require the above steps. Not tested it yet but my steps are for earlier versions that do not have this option. Instead of the option a use option xthis will create the directories but only for extraction, not compression.
