title: Error in setting the path variable in Linux
body: <p>I would like to set a path to the Gnu toolchain downloaded from <a href="https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads" rel="nofollow noreferrer">https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads</a>. I used the line
  $PATH=$HOME/Toolchains/gcc-arm-none-eabi-9-2020-q2-update/bin:$PATH to set the path in the terminal.
  For the first time, I was able to change the path, then I closed the terminal and again set the (wrong) path $PATH=/home/paulson/Toolchains/gcc-arm-none-eabi-9-2020-q2-update/bin:$PATH. Now I am unable to set the correct path and the terminal shows as below.</p>
  <pre><code>paulson@debian:~/Toolchains$ 
  
  paulson@debian:~/Toolchains$ ls
  gcc-arm-none-eabi-9-2020-q2-update
  
  paulson@debian:~/Toolchains$ echo $PATH
  /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
  
  paulson@debian:~/Toolchains$ $PATH=$HOME/Toolchains/gcc-arm-none-eabi-9-2020-q2-update/bin:$PATH
  bash: /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games=/home/paulson/Toolchains/gcc-arm-none-eabi-9-2020-q2-update/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games: No such file or directory
