replace text in file using variable
Hi,
I'm making a script that automaticaly set file size and path in xml file.

I tried with :
Code:
sed -i 's/BOOTPATH/TEST/g' file.xml

it works fine

but if I use a viriable :
Code:
sed -i 's/BOOTPATH/$bootpathf/g' file.xml

with this one, no change are made.

I don't understand why. If a make a
Code:
echo $bootpathf

the displayed value is correct.

Have you tried to use " instead of ' to surround your command?

I was wrong with the '
a modification is made, but it put "$bootpathf" instead of the variable value.

You might be using single quotes. Make sure you use double quotes.
Code:
sed -i "s/BOOTPATH/$bootpathf/g" file.xml

If no good, post your command.

Your previous note:
Quote:
sed: -e expression #1, char 13: unknown option to `s'
leads me to think you are not using the " character, next to the ENTER key

Please post your command.
