SED Question

I need to SED a file and replace:

   Transport Hostname="cscx1001"

with:

   Transport Hostname="9.9.9.9"

Here is the whole command:

cat plugin-cfg.xml | sed "s/Transport Hostname="cscx1234"/Transport Hostname="10.9.9.9"/g" > plugin.xml

I'm having issues due to the "'s around "cscx1234" and "10.9.9.9"

I tried escaping the " with slash, but that didn't work.

After I get the syntax to make this work from the command line I have to take it one step further....

I will be placing "cscx1234" and "10.9.9.9" in variables - HOSTNAME and IP.  If the double quotes were not an issue it would look something like this:

cat ${CONFIG}/plugin-cfg.xml | sed "s/Transport Hostname="${HOSTNAME}"/Transport Hostname="${IP}"/g" > ${CONFIG}/plugin.xml

Any ideas on the correct syntax for these strings?

Thanks,

Lisa

070,

The first statement worked like a charm at the command line, so I assumed the second statement would work as well within the script - but it didn't.

Will you take a look at the script and see if you find anything wrong?  I echoed the HOSTNAME and IP, so I know they are gettting set.  Let me know what you think.

Thanks,

Lisa

*** SCRIPT ***
[wsadmin @ cscx1001:/opt/WebSphere/AppServer/bin/scripts]:> more genPlugin.sh
DT=$(date +%d-%m-%y)
BACKUP=/local/WebSphere/apps/Backup
HOSTNAME=`uname -n`
BIN=/opt/WebSphere/AppServer/bin
CONFIG=/opt/WebSphere/AppServer/config
BOOTSTRAP=$(grep bootstrapPort ${BIN}/admin.config | awk -F'=' '{print $2}')
IP=`ping -c 1 $HOSTNAME | sed "s/)/(/g" | awk '{FS="("}{print $2}'`

echo $HOSTNAME
echo $IP

${BIN}/GenPluginCfg.sh -adminNodeName $HOSTNAME -nameServiceHost $HOSTNAME -nameServicePort $BOOTSTRAP

cat ${CONFIG}/plugin-cfg.xml | sed 's/Transport Hostname="${HOSTNAME}"/Transport Hostname="${IP}"/g'
 > ${CONFIG}/plugin.xml


** OUTPUT ** The "plugin.xml" doesn't have any changes - it is the same as plugin-cfg.xml  ***

/scripts]:> genPlugin.sh
cscx1001  (echo of HOSTNAME)
10.12.90.10  (echo of IP)

/WebSphere/AppServer/config]:> ls -lat plugin*
-rw-r--r--   1 wsadmin  wsadmin        3943 Jun 27 16:00 plugin.xml
-rwxr-----   1 wsadmin  wsadmin        3943 Jun 27 16:00 plugin-cfg.xml

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

You left out the ' between the end of
's/Transport Hostname="
and
${HOSTNAME}
also the 's around
"/Transport Hostname="
and before
"/g'

# ozo's working suggestion improved:
(cat ${CONFIG}/plugin-cfg.xml)|sed 's/Transport Hostname="'${HOSTNAME}'"/Transport Hostname="'${IP}'"/g' > ${CONFIG}/plugin.xml
