how can I override priority between paths of /bin and /usr/local/bin?
Solution 1
You can give /bin/ss
priority by creating a symbolic link to it.
sudo mkdir /opt/ss
sudo ln -s /bin/ss /opt/ss/
and add /opt/ss
to your path before /usr/local/bin
export PATH=/opt/ss:$PATH
$ echo $PATH
/opt/ss:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
to make this permanent, add to the end of ~/.profile
PATH=/opt/ss:$PATH
Solution 2
Your PATH does.
$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:
/bin:/usr/games:/usr/local/games
and please do not just change the path (it will likely change more than just "ss"). Use
/bin/ss -tpla

Today I wanted to run
ss -tpla
command to see network connections, to my surprize I goterror: unknown option -t
. Then I checked location ofss
command:~$ whereis ss ss: /bin/ss /usr/local/bin/ss /usr/share/man/man8/ss.8.gz
As you see I have two
ss
commands, one in/bin/ss
and the other in/usr/local/bin/ss
.I might have installed another application with the same name from source code into
/usr/local/bin/ss
. I don't remember when and usage of it but it's not the command I want to run. Strange thing is that when I runss -tpla
it redirects the command to
/usr/local/bin/ss
I can run actualss
command with/bin/ss -tpla
I thought
/bin
has the priority over other paths.My question is what determines priorities of system paths and how I can override them.
