Suppose I want to compare
gcc version to see whether the system has the minimum version installed or not.
To check the
gcc version, I executed the following
gcc --version | head -n1 | cut -d" " -f4
The output was
So, I wrote a simple
if statement to check this version against some other value
if [ "$(gcc --version | head -n1 | cut -d" " -f4)" -lt 5.0.0 ]; then echo "Less than 5.0.0" else echo "Greater than 5.0.0" fi
But it throws an error:
[: integer expression expected: 4.8.5
I understood my mistake that I was using strings to compare and the
-lt requires integer. So, is there any other way to compare the versions?
