With xx you have a network wide shell based clip board for files and
STDIN/STDOUT: easy data exchange between different accounts on different
hosts.
usage: send file(s): xx file...
or: send STDIN: xx -
or: send pipe: ... | xx
or: get file(s) or STDIN: xx
or: get file(s) quickly: xx --
Pipe example:
framstag@tandem:~: uname -a | xx
/home/framstag/.fex/tmp/STDFEX : 0 kB in 1 s (0 kB/s)
framstag@fex:~: xx
transfered: 0 MB (100%)
Linux tandem 2.6.24-28-server #1 SMP Wed Aug 18 22:01:20 UTC 2010 i686 GNU/Linux
File transfer example:
framstag@tandem:~: xx /boot/
making tar transfer file /home/framstag/.fex/tmp/STDFEX :
/boot/
/boot/initrd.img-2.6.24-27-generic
/boot/vmlinuz-2.6.24-28-generic
(...)
/boot/System.map-2.6.24-27-generic
/home/framstag/.fex/tmp/STDFEX : 34 MB in 2 s (17605 kB/s)
framstag@fex:/tmp: xx
transfered: 34 MB (100%)
Files in transfer-container:
drwxr-xr-x root/root 0 2010-10-20 07:37 boot/
-rw-r--r-- root/root 7905085 2010-05-25 15:38 boot/initrd.img-2.6.24-27-generic
-rw-r--r-- root/root 1927544 2010-10-16 20:38 boot/vmlinuz-2.6.24-28-generic
(...)
-rw-r--r-- root/root 906803 2010-03-24 14:33 boot/System.map-2.6.24-27-generic
Extract these files?
One problem are shared system accounts like root where different persons
use them: xx (like fexsend and fexget) uses $HOME/.fex/id which contains
personal data.
But you can put the ID authorization in the environment variable FEXID.
fexsend on your local account gives you a string for "cut and paste", example:
framstag@moep:~: fexsend -I
export FEXID='fex.rus.uni-stuttgart.de:8080 framstag jmBhf9ht'
history -d $(history 1);history -d $(history 1)
You then copy these two lines with your mouse into the root account:
root@tandem:~# export FEXID'=fex.rus.uni-stuttgart.de:8080 framstag jmBhf9ht'
root@tandem:~# history -d $(history 1);history -d $(history 1)
(The second line deletes these two lines from the bash history)
Now you can use xx (or fexsend and fexget) as normal. Example:
root@tandem:~# grep sshd /var/log/daemon | xx
transfered: 265 kB in 1 s (265 kB/s)
framstag@moep:~: xx | wc -l
434279
After logging out from root@tandem the F*EX authorization data has gone.
Internal details:
The intermediate transfer file container is $HOME/.fex/tmp/STDFEX
When transfering files tar/gzip format is used, whereas STDIN (pipe) will
be transfered uncompressed. Tip: If you want to transfer files uncompress,
then use: tar cvf - your files... | xx
With default usage only one "storage slot" is available: STDFEX
But you can use as many "storage slots" as you want by using "xx :TAG"
Examples:
uname -a | xx
grep sshd /var/log/daemon | xx :log
xx :log | grep obertux
xx :config /boot /etc /root
xx :config --
|
