[SOLVED] bash script creating a newline character?

Issue

Hi I have a script to read 4.29.0 and convert to 4-29-0

The raw file I am reading is this:

$ cat package.xml  | grep version
<?xml version="1.0"?>
  <version>4.29.0</version>

The command I have to read is this:

VERSION=$(grep "version" package.xml | awk -F '>|<' '{print $3}' | sed 's/\./-/g')

If I print it

echo "testing.. $VERSION"

This will print as follows

testing.. 
4-29-0

Why is there a new line character and how do I remoev this ? I want to see the string as

testing.. 4-29-0

Solution

Your initial grep is not sufficiently focused. You need to change

VERSION=$(grep "version" package.xml

to

VERSION=$(grep "<version>" package.xml

to ensure only the line that has the relevant content will be processed by the awk command.
