Hi,

I'm trying to assign the output of a command to a variable and then concat it with another string, however, it keeps overwriting the original string instead of adding on to the end of the string.

Contents of test.txt --> This is a test

var1="`head -n 1 test.txt`"
echo $var1 (This is a test)

var1=$var1"123"
echo $var1 (123s is a test [instead of: This is a test123)

The issue has something to do with the first line. If I simply assign a string like this:
var1="This is a test" , then it all works, but when I try to assign the output of a command to a variable, it does not add to the string properly.

Does anyone know how to get around this??

Thanks!!
