Purpose:Add, update, or delete files in a Java .JAR archive


Format:JAR [/A:[[-][+]rhsdaecjot] /A /C /D /F /Ln /M /Ne /Nt /O:[-]adegnrstu /P /Q /R /TEST /U /V] jararchive [@file] file...


jararchiveThe jar file to work with
fileThe files(s) to be added to the jar file


/A:... (attribute switch)/O:... (sort order)


See also UNJAR.




After compression, the .JAR file may then be imported into Java code or executed by a JVM. The syntax is similar to the ZIP command:




/A:...Select only those files that have the specified attribute(s) set. See Attribute Switches for information on the attributes which can follow /A:. Do not use /A: with @file lists. See @file lists for details.


You can specify /A:= to display a dialog to help you set individual attributes.


/AAdd the specified file(s) to the Jar file. (This is the default.)


/CDisplay (on standard output) the contents of a file in the Jar archive.


/DDelete a file in the Jar archive.


/FUpdate only those files that currently exist in the tar file, and which are older than the files on disk.


/LSet the compression level (0-6)..


/MDelete the files from the disk after adding them to the tar file.


/O:...Sort the files before processing.


You may use any combination of the sorting options below. If multiple options are used, the files will be sorted with the first sort option as the primary key, the next as the secondary key, and so on:


nSort by filename and extension, unless e is explicitly included. This is the default.
-Reverse the sort order for the next sort key
aSort names and extensions in standard ASCII order, instead of numerically when numeric substrings are included in the name or extension.
dSort by date and time (oldest first); also see /T:acw
eSort by extension
gGroup subdirectories first, then files
rReverse the sort order for all options
sSort by size
tSame as d


/PDisplay the progress (0 - 100%) for each file as it is archived.


/QDon't display the files being archived.


/RIf the argument is a subdirectory, copy all of the files in that subdirectory and all of its subdirectories to the tar archive.


/TESTTest the integrity of the TAR file (header and contents). Any errors will be displayed on STDERR.


/UUpdate files which either don't exist in the tar, or which are older than the files on disk.


/VView the list of files in the tar file (date, time, size, and filename
