Use the "r" operation instead of "c" to append files to an existing
archive.

Maybe he can find something like:

tar uf $FILE $PATH

That's not the faster option.

Re: How to add files into a tar file

I tried before. 'r' just for tar file into file(*.tar) not for tape.

Please, don't top post,

r and u options are supported when writing to a tape device.

How don't top post ? Somtime, user feedback like this.

Some unix systems use different file names to either automatically rewind
the tape drive, or to keep it in the same place when closing.

Be aware that putting a new record on a tape is different from
appending to an existing record.

It's also safer. If one of the records is bad, you can use mt(1) to
skip over that record to read the next.

It works.

#tar cvf /dev/rmt/2m *.txt
a abc.txt 6 tape blocks
a dump_time.txt 59 tape blocks
#tar rvf /dev/rmt/2m *.txt2
a drwg.txt2 282 tape blocks
a y.txt2 5 tape blocks
#tar rvf /dev/rmt/2m *.txt2
a drwg.txt2 282 tape blocks
a y.txt2 5 tape blocks


#tar tvf /dev/rmt/2m
-rw-r--r-- 0/1 2754 Nov 3 08:54 2005 abc.txt
-rw-r--r-- 1013/10 29882 Jan 16 08:48 2006 dump_time.txt
