Linux command jar to display a list of java files
While the contents of a war file can be displayed with the zipinfo or less command, the list of files in a jar file can be displayed with the jar command.
jar tf a.jar
You will now see a list of jar files.
jp/co/confrage/a.class jp/co/confrage/b.class jp/co/confrage/c.class
The options for the jar command are as follows. See the man command for details.
|t||List the contents of the archive|
|f||Specify the archive file name|
|v||display process contents on command line|
If the “tf” option is used, information such as file size and date will also be added to the display.
If you want to know the file size of a certain class, you can check the file size as follows.
jar tvf | grep hoge.class
