ENV PATH Variable update Link to heading

I have recently installed SNAPD and HUGO. But i am unable to run this “hugo version” as the installed folder does not fall under the default /bin or /usr/bin. Refer the error

$ hugo version                                                                                                                                                      127 ⨯
Command 'hugo' is available in '/snap/bin/hugo'
The command could not be located because '/snap/bin' is not included in the PATH environment variable.
hugo: command not found

Default ENV variables

env | grep PATH
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/home/rocky/.local/bin

You can see /snap/bin does not fall under this. To add this at the end of existing use this command

export PATH=$PATH:/some/new/path

To add the new path prepending the existing values Use this

export PATH=/some/new/path:$PATH

To keep Only new path Use this command( remember if any programs under /bin or /usr/bin will not work without mentioning the full path after this)

export PATH=/some/new/path

In this case I am adding new path to the end of existing PATH variables.

export PATH=$PATH:/snap/bin

┌──(rocky㉿kali)-[~/mysite/exsite]
└─$ env | grep PATH            
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/home/rocky/.local/bin:/snap/bin

Now the Hugo command works as well( no need to manually type /snap/bin/hugo)

hugo version
hugo v0.93.3+extended linux/amd64 BuildDate=2022-03-08T16:34:16Z

However this is not permanant and valid for only existing session. Refer my output after reboot

Command 'hugo' is available in '/snap/bin/hugo'
The command could not be located because '/snap/bin' is not included in the PATH environment variable.
hugo: command not found

Repeat the export command once again. The edit the /etc/enviornment

Now the new path has been added permanatly. To test you can open a new sesison or after reboot issue this command test

env | grep PATH 
$ env | grep PATH                                                               
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/snap/bin:
