Install ifort on Ubuntu 20

I am trying to install the ifort compiler on Ubuntu20. I downloaded the installation file from the site: intel

enter image description here

This is a file with the extension .sh, which I made executable:

  Downloads$ chmod +x l_fortran-compiler_p_2021.1.2.62_offline.sh
  Downloads$ ./l_fortran-compiler_p_2021.1.2.62_offline.sh

This opened the software installer:

enter image description here enter image description here

However, I cannot use the ifort compiler. Example:

  ifort -o name name.for

It gives the following message:

  Command 'ifort' not found, did you mean:

    command 'fort' from deb fort-validator (1.2.0-1)
    command 'isort' from deb isort (4.3.4+ds1-2)

  Try: sudo apt install <deb name>

I need to install the intel ifort compiler because the executable is faster if I compile with the -fast option.

there is also a file named modulefiles-setup.sh with setvars.sh file ,in the same folder(/intel/oneapi/) . you need to activate both files with command(source file.sh) to see ifort and icc commands. use this commands:

 source intel/oneapi/setvars.sh 

 source intel/oneapi/modulefiles-setup.sh

 source .bashrc

You have to "activate" the intel compilers with:

source /opt//oneapi/setvars.sh

The documentation says how to set the environment:

For root or sudo installations:

. /opt/intel/oneapi/setvars.sh

For normal user installations:

. ~/intel/oneapi/setvars.sh

You can put these into your bash profile or bashrc.
