ok, here is what I want to do ..
| Quote: | | [root@host1 ]# ssh host2 "sed -e 's/^/'"`hostname`"' /' /tmp/part3" |
and what I get back is
| Code: | host1 root somehost Tue Apr 10 16:25:50 -0400 2012
host1 alice beast Thu Jun 3 09:38:42 -0400 2010
host1 fred hulk Tue Apr 24 11:04:26 -0400 2012 |
i am expecting the `hostname` to get run on the box that I am doing the ssh to.. but it appears that somehow its getting executed on the local box that im running the ssh command from.
WTF?!

... very funky quoting you've got there. Either that should be fixed, for instance $(hostname) (backticks are bad...) or just write the command in a script on the remote host and execute this?!

yeah i need the funky quoting to get the hostname command to run within a remote loop over ssh . ..
I could make the program run remotely, but I am going to run this command over a bunch of hosts in a loop, so that wouldnt be a very good option.

| To elaborate on the hint that avx gave you, why are you running hostname locally and inserting its contents into the otherwise remote string? |

ok
ssh host2 'sed -e "s/^/$(hostname) /" /tmp/part3'
