Today I wanted to sftp a 10Gb file over the wire. Knowing that the transfer would fail in the middle of it, I decided to split this file into small pieces beforehand. Below I think is the easiest way on osx.
// to split my huge file into 100mb files, having the prefix "bak_" split -b 100m my_huge_file.ext bak_ // to re-construct my huge file cat `ls bak_*` > my_huge_file2.ext
After running the split command, you will see some files named bak_aa, bak_ab, etc in your directory. These are the chucks of your original huge file. So just transfer these small bak_* files over the wire.
sftp doesn’t have mput… sigh…
Also the original file name is gone missing in the process… sigh… That’s unfortunate. What I decided to do is to write up a small readme file to store the above two commands, so later on I know what output filename to use when running the second command.
