I have two files in my directory,
the multiply.txt file contains only a single line 3*6
I want to display the value of the expression in the multiply file using only echo and cat commands.
the runner.txt contains the shell script required
I have tried
echo $((cat multiply.txt)) #didnt work
I also tried to extract 3*6 as a string into a variable and none of the below commands seem to do the trick.
value = cat<multiply.txt # didnt work
cat multiply.txt # didnt work
value = $(cat multiply.txt)
