If you are trying to compile your code with gcc, you need to use gcc as the command. Commands in bash are case sensitive.

Bash, like other Linux shells, is case sensitive: GCC is not the same as gcc, and you want to use gcc.

If even gcc doesn't work, it means:

  • You didn't install it, which you should do with the following commands.

    sudo apt-get install build-essential
    sudo apt-get install gcc
    
  • The command is not in your $PATH. In this case try first env | grep path, and then gcc hello.c -o hello1. If it doesn't work, find where gcc is with find . -name gcc, and add its path with export PATH=$PATH:/path/to/gcc. (Replace /path/to/gcc with the path where gcc was find with the previous command.)
