Split Command... How to Rejoin?

Quantumstate · 11-03-2006, 02:19 PM

I've just lost an hour of my life to this stupid problem.

I need to split a file into pieces (madwifi), so I can move it over on floppy to my machine with malfunctioning network. I used split, and it divided it up just fine. But for the life of me, I can not figure out how to rejoin the files at the other end.

cp and mv do not have an append function. cp infile1 outfile does fine, but when I cp infile2 >> outfile, it gives "missing destination file operand after infile2". cp infile1,infile2 outfile doesn't fscking work.

join and paste are the wrong things. dd if=infile1,infile2 of=outfile doesn't work either. Maybe I should be using dd in the first place. I am enraged.

I use cat to restore it.
For example:

Code:

#ls -lh

total 62M
-rw-r--r--  1 root   root    62M Dec 25 23:55 aclinux.zip

To split aclinux.zip into files which are slightly smaller
than 9M , use the command: split -b 9000k aclinux.zip

#ls -lh

total 123M
-rw-r--r--  1 root   root    62M Dec 25 23:55 aclinux.zip
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xaa
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xab
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xac
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xad
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xae
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xaf
-rw-r--r--  1 root   root   8.6M Dec 26 00:01 xag


Restore the file with the command: cat xa* > aclinux-restored.zip

#ls -lh

total 185M
-rw-r--r--  1 root   root    62M Dec 26 00:10 aclinux-restored.zip
-rw-r--r--  1 root   root    62M Dec 26 00:06 aclinux.zip
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xaa
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xab
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xac
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xad
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xae
-rw-r--r--  1 root   root   8.8M Dec 26 00:01 xaf
-rw-r--r--  1 root   root   8.6M Dec 26 00:01 xag

Thank you, that worked.

(Of course! I should have known it would be cat... {smirk})
