How to assign echo in variable

I've testing the following code:
PHP Code:
echo test.txt cut -. -f1 
and get the output "text"

So why can't i assign the command to a variable?
PHP Code:
VAR='"echo test.txt | cut -d . -f1"'
echo $VAR

Because your quotes are in the wrong place. Try this:


Code:
  var="`echo test.txt | cut -d . -f1`"

Or the preferred way (no backticks)
Code:
var=$(echo test.txt |cut -d . -f 1)

If you can use $(...) you can use and other POSIX feature:
Code:
VAR=test.txt
echo ${VAR%.txt}

Good point, but probably better off using ${VAR%%.*}since the OP was wanting to cut field 1. The example was test.txt, but the input string might be foo.bar.txt.
