- Subject: Can I use a variable in sed?
I'm trying to write a script that allows me to change the port number
depending on when environment I'm in. I can pass in the port number to
my script, but I stuck trying to get sed modify my file with my port
number variable. Here is the line I'm executing
sed '1,$ s^8080^$Shutdown_Port^' <./temp.xml >./server.xml
Since my line started out to be
<Server port="8005" shutdown="SHUTDOWN">
Since Shutdown_Port was 9300, I thought the resulting line would be
<Server port="9300" shutdown="SHUTDOWN">
Instead, I got:
<Server port="$Shutdown_Port" shutdown="SHUTDOWN">
What am I doing wrong here? Can sed be passed a variable?
thanks,
Jerome
