existing in tar backup of catridge.

To see if a file exists in a tar archive, you could use the t command. For example to see if the file data/files/myfile exists in the tarfile file.tar you could do this:

You might also employ grep to look for any files whose name contains the text "myfile" (note grep is case sensitive unless you specify the -i option):

You can delete files from a tar archive using the --delete option, but this is not for use with tapes - just if you are using tar files as a container format (e.g. for distribution of groups of files).

I recommend you take a look at the tar tutorial for more information, not to mention the manual and infotex pages which most likely are installed on your linux system. To access these, just type "man tar", and "info tar".

You can use an easy program like Ark or Karchiver. If you want to use the command line the command is:
For more info write tar --help or look at gnu tar manual.

IMPORTANT NOTE from the tar info page (emphasis mine):

i.e. don't do it on a tar archive which is on a tape drive.

Thank you for noting!
