I just installed picc-9.82.9453-linux.run from Microchip website, and at the end it asked me

==> NOTE: You may wish to add the following
/usr/hitech/picc/9.82/bin
to your PATH environment variable.

What does it mean?

I also need to add this to the environment path

NOTE: You may wish to add the following
/usr/hitech/picc-18/pro/9.66/bin
to your PATH environment variable.

PATH is a global operating system variable that contains names of files that are to be executed without specyfing the whole path to them. For example You can just write startx to start graphic environemnt instead of /bin/some other folders/startx –  Misery May 24 '12 at 15:56
    
After editing .profile restart your system to get the changes to take effect. (Perhaps there is a way around this, but restarting certainly works) –  thn May 30 '13 at 8:42

Partial duplicate: How to add a directory to my path?

PATH is an enviroment variable. Basically, it tells your machine were to search for programs, so when you run your picc program, you can just do this:

picc

instead of

/usr/hitech/picc/9.82/bin/picc

To add a directory to your $PATH, follow any one of the below.

  1. simply edit ~/.profile

    gedit ~/.profile
    

    find the following line:

    PATH="$HOME/bin:$PATH"
    

    and change it to:

    PATH="$HOME/bin:$PATH:/usr/hitech/picc/9.82/bin"
    
  2. Run the below command in terminal

    export PATH=$PATH:/usr/hitech/picc/9.82/bin

Just keep adding a colon, then your new path to that string. i.e. PATH="$HOME/bin:$PATH:/usr/hitech/picc/9.82/bin:/my/new/path" –  reverendj1 May 24 '12 at 16:37
