mkdir command not found?
I think I messed up the PATH. I was installing Bioperl and tried to changed path. The correct code should be:
$ export PATH=/usr/local/ActivePerl-5.26/bin:$PATH
$ export PATH=/usr/local/ActivePerl-5.26/site/bin:$PATH
$PATH=/usr/local/ActivePerl-5.26/bin:$PATH
$PATH=/usr/local/ActivePerl-5.26/site/bin:$PATH
export PATH
--
But I did something stupid and what I typed is attached. Although Bioperl is installed, the ls or mkdir command are not working any more.

The first time you ran export PATH=/usr/local/ActivePerl-5.26/ it replaced your entire previous path with that one single directory.
Subsequent attempts to "do the right thing" were now using the new path, so when you ran PATH=/usr/local/ActivePerl-5.26/bin:$PATH, what that did was update the PATH variable to contain the following string:
/usr/local/ActivePerl-5.26/bin:/usr/local/ActivePerl-5.26/
To recover from this situation, you have a few options:
1. Explicitly set the path to be what you want
Run something like the following (edit according to your requirements:
export PATH=/usr/local/ActivePerl-5.26/bin:/usr/local/bin:/usr/bin:/bin
2. Source your bashrc or bash_profile to reset the environment
You probably have your default path set in either ~/.bashrc or ~/.bash_profile. Let's assume it's in ~/.bashrc, then you can reset it like so:
. ~/.bashrc
Which is short for:
source $HOME/.bashrc
3. Start a new shell session
It might be simplest to just abandon the current session and start over. Close the terminal and open a new one; or go into a new shell inside the current terminal by running /bin/bash
