using variables in sed statements

[hcclnoodles]

Hi there,

I need to be able to put the hostid of my box into a file (replacing the text "enter_hostid_here" so i tried


sed -e 's/enter_hostid_here/`hostid`/g' inputfile > outputfile



but it takes the `hostid` literally as text .....how can I get this info into the file (ideally in a single line)

I notice also that you cant call $VARIABLES in sed statements either as they too are taken literally

any help would be great
Cheers

Either:

[tt]sed -e 's/enter_hostid_here/'`hostid`'/g' inputfile > outputfile[/tt]

or:

[tt]sed -e "s/enter_hostid_here/`hostid`/g" inputfile > outputfile[/tt]

` characters between single quotes are treated literally, so you either need to terminate and reopen the single quotes, or use double quotes.
