starting command [solved]

[Lando]

I've an old Firefox in /usr/bin that start typing "firefox" on a terminal . Now I've installed the last firefox version and I'd wish to start it

from the terminal . What have I to change to do that ? ( I want to keep also the old version...) .

Thanks.

You could either start the new version by typing the full path, such as /usr/local/firefox, or create a symlink to the new version in a directory in your PATH. If the latter, be sure the symlink has a unique name to avoid conflict with existing commands.

where can I see an example ( the new path is /home/lando/Firefox1.5/firefox and the old one is /usr/local/firefox ) ? I

This:

 

/home/lando/Firefox1.5/firefox

 

is not in PATH which means you would have to give the above full path in a console to start your updated firefox. That will probably get old in a real hurry. You can handle that in two ways - you can edit your ~.bash_profile file to add /home/lando/Firefox1.5/ to PATH or you can craeate a link to /home/lando/Firefox1.5/firefox to some directory that is already in PATH. The second is a little easier:

 

$ su
<enter root password>
# ln -s /home/lando/Firefox1.5/firefox /usr/bin/firefox1.5

 

After running the above you can launch your new firefox with:

 

$ firefox1.5

I've added the link below in /usr/bin , but typing "firefox" I get "command not found"

 

ln -s /home/lando/Firefox1.5/firefox/firefox

 

Still I get "command not found" with the .bashrc below >>>>>

 

**************************************************

# .bashrc

 

# User specific aliases and functions

 

# Source global definitions

if [ -f /etc/bashrc ]; then

. /etc/bashrc

fi

 

export PATH=$PATH:.

 

PATH=$PATH:/home/lando/FIREFOX_15/firefox

export PATH

 

******************************************************

 

Where is my mistake ?

Thanks.

You didn't type the ln -s command correctly. Therefore, it would have attempted to create a symlink called firefox, and of course, one already probably exists in this directory. As pmpatrick said, it should be created as this:

 

ln -s /home/lando/Firefox1.5/firefox /usr/bin/firefox1.5

 

then it would have worked, because you forgot to put "/usr/bin/firefox1.5" at the end of your ln -s command. It can't overwrite /usr/bin/firefox if it already exists, as this is what it tried with your command.

[Lando]

It doesn't work..........

 

[lando@localhost ~]$ su

Password:

[root@localhost lando]# ln -s /home/lando/Firefox1.5/firefox /usr/bin/firefox1.5

[root@localhost lando]# firtefox

bash: firtefox: command not found

[ianw1974]

That's because you should type:

 

firefox1.5

 

to get it to work. The symlink says firefox1.5, thats why when you type firefox it doesn't work! Or firtefox from your text above is incorrect also.

[Lando]

No...firefox1.5 is the folder containing the folder "firefox" that contains the "firefox" script

 

ln -s /home/lando/Firefox1.5/firefox /usr/bin/firefox1.5

couldn't be correct ?

[ianw1974]

Yes, because the first part of the ln command is where firefox 1.5 exists, and therefore it shows firefox1.5/firefox. The /usr/bin/firefox1.5 is so that you can execute it.

 

When you type firefox1.5, it looks at /usr/bin and then this symlink knows that firefox1.5 isn't here, but in /home/lando/firefox1.5/firefox and it will run this command.

 

So yes, it's correct. Type:

 

firefox1.5

 

if it doesn't work, your symlink hasn't been created properly:

 

ls -l /usr/bin/firefox*

 

and see what it says for symlinks in this directory that follow the firefox pattern plus any other detail after when using the asterisk.

[Lando]

It works only if I do : cd /usr/bin /FIREFOX_1.5

then firefox

But it's not what I wanted...it has to work typing "firefox" on any directory the terminal is opened.

 

Below your request >>>>>

 

[root@localhost bin]# ls -l /usr/bin/FIREFOX_1.5

lrwxrwxrwx 1 root root 31 lug 11 10:20 /usr/bin/FIREFOX_1.5 -> /home/lando/FIREFOX_1.5/firefox/

[ianw1974]

You've set the symlink up wrong then, if you have to go into a directory called firefox_1.5 in /usr/bin.

 

For it to work, it HAS to be in /usr/bin. Here is a sample for you from my system, and you can use this on yours, and it should work.

 

[root@europa firefox]# ln -s /usr/local/mozilla/firefox/firefox /usr/bin/firefox
[root@europa firefox]# cd /
[root@europa /]# ls -l /usr/bin/fire*
lrwxrwxrwx  1 root root 34 Jul 11 14:36 /usr/bin/firefox -> /usr/local/mozilla/firefox/firefox*

 

replace /usr/local/mozilla/firefox with the path to your version of Firefox 1.5. I installed Firefox 1.5 on my system in /usr/local/mozilla/firefox as you can see from my example.

 

If it still fails after this, then you're definitely not following it properly.

[Lando]

Our settings are equals.....To do working all the stuff I have added in .bashrc > PATH=$PATH:/usr/bin/FIREFOX_1.5

export PATH

I don't know why...every thing in /usr/bin isn't searched first of all ...?

[ianw1974]

It should be, mine searches perfectly fine by just putting the symlink in /usr/bin. I think your problems are occurring because you're trying to put them in a sub-directory called firefox_1.5 in /usr/bin. I would suggest putting the symlink in /usr/bin like I did.

Your is >>>> /usr/bin/firefox

mine is >>>> /usr/bin/FIREFOX_1.5

 

[root@europa /]# ls -l /usr/bin/fire*

lrwxrwxrwx 1 root root 34 Jul 11 14:36 /usr/bin/firefox -> /usr/local/mozilla/firefox/firefox*

 

 

root@localhost bin]# ls -l /usr/bin/FIREFOX_1.5

lrwxrwxrwx 1 root root 31 lug 11 10:20 /usr/bin/FIREFOX_1.5 -> /home/lando/FIREFOX_1.5/firefox/

 

It seems much the same ..........
