Just curious: why don't you use the hostname used for the scp connection? Is it different from the machine's hostname output?

Code:
scp -p "$host:/tmp/$host.html.gz" ...

Ooops, I just saw that Scott had already asked the same question Smilie

I dont want to redirect the name to a local file, otherwise I would've done it.

How can I save the output of a command to a local variable in my script, not to a local file?

my host is server1
my hostname includes the domain.... server1.domain.com

Same way you do it any other time.

Code:
VAR=$(ssh username@host 'cat /tmp/$(hostname).gz')

I don't think this will work for scp, because I see no way to make it print the retrieved file into standard output. again, scp is not a shell.

I understand, and what's the problem with the solution(s) provided by Corona688?

Then, just: scp $host:/tmp/$host.*.whatever ...

There's surely only one file on each host you want that matches that?

yes of course, that is the workaround, but what if for some reason, the hostname does not come out with the domain name...then the script will fail!! Smilie

that is why i want to store the vale of the command "hostname" of the remote server on my script, because that way I know for sure that the file is named with that same name. does that makes sense?
