Join multiple Split files in Unix
Hi,
I have a big file of 50GB size. I need copy it to a second ftp from a ftp. I am not able to do the full 50GB transfer as it timesout after some time. SO i am trying to split the file into 5gb each 10 files with the below command.
split -b 5368709120 pack.tar.gz backup.gz
After I transfer these files to the second ftp, what is the command I need to use to join the files into a single file properly. Can some one please help me over here. Can you also please suggest If there is any good way of transferring the whole file at once?
Thanks.
