Very much a beginner here. I am teaching myself how to write Bash Scripts. I am going through a lesson called “Shell Scripting for Beginners – How to Write Bash Scripts in Linux” and so far, so good.
I am however having a problem trying to expand on a sample in the lesson regarding looping with numbers. When I create a script as described in the lesson:
for i in {1…5}
do
echo $i
done
And run the script, the output is as expected. My screen shows, vertically, the numbers 1 through 5. However, I would like to allow the use of a variable, input by the user, as the “top” number in the count. For example, I want the user to enter the number they want the script to count to, and have the vertical list go from 1 to that number. Here’s the script I wrote:
echo “Runs a loop”
read -p "What do you want the loop to count to? " count
for i in {1…$count}
do
echo $i
done
And here’s the output (I typed in the number “7”). As you can see, the script did not perform as expected. Instead of counting from 1 through 7, it simply printed the following:
Runs a loop
What do you want the loop to count to? 7
{1…7}
So, any suggestions would be very much appreciated.
Thank you…
