sed and variable value with a space issue

[sandeep t]

I have a file called file1
file:

component

In file1, I want to append one line after the first line which contains 'component' and store it in a file2. So my file 2 should like this:
file2:

components
<component name="DB Tools" displayDescription="false ">

This is my script which should do the above things.
script:

var="DB Tools"
sed '/components/a\
<component name="'$var'" displayDescription="false ">
' < file1 > file2

When I run the script I get following error:
sed: input file "Tools" displayDescription="false ">
": The system cannot find the file specified.

How can we fix the above error without using IFS?

Try this:

sed '/components/a\
<component name="'"$var"'" displayDescription="false ">
' < file1 > file2

Thanks, it worked! Sed sometimes looks tricky.
I was planning to use ant for the same purpose, but didn't find task which can so this. But that is another topic and need not be discussed here.

I'm not going to contradict that, but the problem here is not related to sed at all. It is related to quoting.

Agreed.

I was wondering how can we use sed append when the string after which I want to add a line is present in two lines.
For ex, this is my script:

<components>
<folder name="bin"/>
<components>

I want append a line and the output file should look like this:

<components>
<folder name="bin"/>
<components>
<component name="Server" />

Ofcourse, blindly I can't use
sed '/<components>/a\
<component name="Server"'

Can I take the reference of "folder name=bin" line?
