Comments on: How to split large file into several smaller files – Linux

I think froff meant the really single – .
From the split manpage:
“With no INPUT, or when INPUT is -, read standard input.”

For example, it tells split to read from the pipe (created by the ‘|’) instead of a specified file. Or it tells tar to write to standard output.

By the way, this article / discussion is really helpful!

the – is the way to include additional options.
it’s very common in linux and unix

hello
What does that ‘-’ single character mean in command line?

Whoops, guess I should have proof read that.

After the tar commands, and parameters (jcf, cf, cfz, etc.) and after the -, you’ll of course need to tell it what file(s) to use and/or what directory and after the split command and parameters, just before the output filename, be sure to use the final – as well.

Here’s a better, yet simple example (remove quotes):
“tar cvfp – filename.iso |bzip2 -9 -c |split -a 3 -db 500M – split_file.tbz.”

Attention to: Grahack

gzip:
tar cfz – |split -b 100M split_file.tgz. (note the last dot, optional though)

gzip with level 9 compression:
tar cf – |gzip -9 -c |split -b 100M split_file.tgz.

bzip2:
tar jcf |split -b 100M split_file.tbz.

bzip2 with level 9 compression:
tar cf – |bzip2 -9 -c |split -b 100M split_file.tbz.

then simply cat split_file* > file.tgz or .tbz and untar/gunzip or bunzip2 accordingly.

In most Linux distro’s, this should work as is. In OpenBSD or FreeBSD, I think the syntax may be a little different – the man pages will say though. As for other *nix OS’s, YMMV. =)

Hope this helps…

Hi all,
resurrecting this old interesting post to ask a question about tar.
I’m creating an archive doing:

tar cfz /media/disk/0912171726.tar.gz /data

Is there a way to use ’split’ and a pipe to create a few files WITHOUT creating the big file first?

for 3gp files they have a header that quicktime or other players look for to be able to play it. So you cannot use split to split it to 2 3gp files ever you change the extension. You have to use a special splitter for media files that copy also the header of the file.

not really familiar with 3gp file.
but i think u can try Ulead media studio, or Adobe Premier.
Both are good for video editing.

Okay, thanks for your reply.

Do you have any suggestions for a suitable video editor?
