When the update sub-option is used, dates on the files specified for archiving are compared against dates of files having the same name already present in the archive. PKZIP allows you to specify that only new or modified files are added to an archive. The update sub-option can save time when you repeatedly archive the same files.
You can change the default with the configuration command to modify the default setting for add.įor information on how to change default values for commands and options, see this page. Note: The add command uses the all sub-option to add all files in a specified directory to your archive file by default. The resulting test.zip file is stored in the current directory (the parent directory to the temp directory in our example). For example, if you were in a parent directory to a directory called temp and you wanted to compress all the files in the temp directory, you could type the following: You can also specify files from a different directory if you wish. (To learn how to compress files that appear in subdirectories, see " Compressing Files in Subdirectories" later in this chapter.) In the example above, all files in the current directory are compressed into the test.zip file. Simply type pkzipc -add, and the name of your ZIP file, as shown below: To do this, you do not have to specify each file. You can choose to compress all files in a particular directory with a single command. Pkzipc -add myarchive.zip *.txt Adding All Files in a Directory txt files in the current directory to myarchive.zip. If the archive does not already exist, PKZIP creates it. To add files to a new or existing archive, specify the name of the archive on the command line, then list one or more files to add. The add command adds files to an archive. See this page for information on how to change default settings. The default value determines the way that the command or option is done when the command or option is used on the command line by itself, with no sub-option explicitly specified.įor example, the initial default value for the add command is all, which causes the command to add all files.
Default Values for Commands and Optionsįor each operation in this chapter, the command or option that represents that operation has a default value. This chapter contains detailed information on the features and options available when you add files to an archive.
Unzipping a file from the command line is pretty straightforward using unzip -d. non-existent-folder/fontsĬheckdir: cannot create extraction directory. If you want to unzip into a subdirectory of this folder, you’ll run into an error. If you want to extract the archive into a non-existent folder path, you’ll run into errors.įor example, a directory non-existent-folder does not exist in the current path. Notice: the unzip command won’t create non-existent paths on your disk. Instead of polluting the current directory with extracted files, you may unzip the files into a new folder using the unzip -d flag: # “unzip -d” extracts the content into a directory It’s a command-line utility allowing you to unzip a compressed file.īy default, the unzip command extracts the ZIP’s contents into the current directory.
