SSSU shell scripting

Lan_4 — Mon, 17 Feb 2014 07:28:46 GMT

I am making a shell script run sssu.
The script looks like this:
SNAP=...
HOST=...
sssu <select manager ... username=administrator password=administrator
select cell ...
add lun 3 vdisk="$SNAP" host="\Hosts\${HOST}"
exit
EOF

I am having troule with those "\" in the name
of host. Is there a better way to preserve the
real meaning of "\", don't try it as a special
character.

Thanks.

Yes, isn't it great that they designed it that way? Can you escape the \ using \\ in the symbol assign?

Tried.
like, host="\\Hosts\\${HOST}"
It did not work.
Thanks.

One problem with your original is that the \$ prevents ${HOST} from being evaluated.

Did you try:
(notice the 2 \\ before $)

HOST=yoyo
SNAP=vol1
cat <select manager ... username=administrator password=administrator
select cell ...
add lun 3 vdisk="$SNAP" host="\Hosts\\${HOST}"
exit
EOF

which produces:

select manager ... username=administrator password=administrator
select cell ...
add lun 3 vdisk="vol1" host="\Hosts\yoyo"
exit

I had to use 'cat' because I don't have access to SSSU right now.

The trick for "\\" worked for most of cases, but not with the hostname starting with
"n", "t", "a", "f", because
"\n","\t","\a","\f" are escape characters.
It happened that I have two hosts with names
starting with "a" and "f". I guess the solution
is to "hard coded" them into the script.

Thanks to all.
