change word in a property file
Hi,

I have a property file called "inspector.properties".
In this property file stands the following:
inspect=ON

Now I want to have a shell script that when you run it, changes the ON in OFF in this property file.
Is this possible with sed?

Can anybody help me with this?
Tnx very much.

Try:
Code:
perl -i -pe 's/(inspect=)ON/\1OFF/' file

Code:
echo ",s/^inspect=ON$/inspect=OFF/\nw\nq\n" | ed -s inspector.properties

Maybe stupid question, if you use this perl command, is it still needed to define this above in the script? #!/bin/ksh

So:
#!/bin/ksh
perl -i -pe 's/(inspect=)ON/\1OFF/' file

If you want to run that command inside a script, then yes.

with sed:
Code:
sed -i 's/inspect=ON/inspect=OFF/g'

If you are running on a Mac or a version of sed that errors out on the first one then try:
Code:
sed -i .bak 's/inspect=ON/inspect=OFF/g'

In a script
Code:
#!/bin/bash
echo "What is the full path to the Inspector.Properties file?"
read file
sed -i 's/inspect=ON/inspect=OFF/g' "$file"
if [ $? -ne 0 ]; then
sed -i .bak 's/inspect=ON/inspect=OFF/g' "$file"
else
echo ""
fi
exit 0
