Joining files created by the SPLIT command

Alexander Laing — Mon, 05 Dec 2005 15:10:37 GMT

Hello,

I have a file named "backup.tar" file that is greater that 2Gig. When trying to dump the file to tape, using the "tar" command, the error occurs indicating that the file is more than 2Gig.

To get around this problem I used the UNIX "split" command to split the backup.tar file in to two 1Gig files - backup01.tar and backup02.tar.

What I would like to know is that for recovery purposes, after the two tar files have been restored from tape, how do I properly join them back to form the one "backup.tar" file?

Thanks in Advance.

Shalom Alexander,

Please make sure the filesystem you are assembling these files on permits largefiles.
cp backup01.tar > backup.tar
cat backup02.tar >> backup.tar

try :
cat backup01.tar backup02.tar > backup.tar

All you have to do is cat them.

cat backup.01.tar backup02.tar > backup.tar

Split creates filenames that are lexically ordered, eg, myfileaa, myfileab, myfileac ...

so that

cat myfile* > myfile does just what you want to do.
