Hello Everyone,

I am trying to read a file which contains numbers(Floats and integers) line by line, I am able to read the line correctly and it works fine, but when I try to compare it with a different number I am failing at that point

test.txt contains numbers as:
10.5
0.52
78.5
29.8
45
13
21.45
0.02
0.99
1.00


if the number in text file is greater than 30 then print greater else print smaller.

I am new to programming

Thanks in advance

What I have tried:

Here is my code:

#!/bin/bash

file=~/test.txt
while IFS= read -r line
do
    echo $line
        if [[ "$line > 30" | bc) -eq "1" ]]; then
            echo Greater
        else
            echo Smaller
        fi
done < $file

You can use normal comparison operators inside a bash [[ ]] expresion.
Try
Bash
if [[ $line > 30 ]]; then
    ...
fi
