Script, FF incompatibility

Post#1 by Ed_P » 21 Jul 2014, 15:54

I have a script that invokes Firefox with a URL that Firefox rejects because the script passes the URL misformed. How do I get the script to pass what I give it?

Code: Select all

firefox "/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF" 2>/dev/null &
exit 0

Code: Select all

File not found

Firefox can't find the file at /mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF.
And the reason is the URL in the URL field is:

Code: Select all

file:///mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%3Fb=FF
If I manually change the %3F back to ? or manually paste the URL into FireFox's URL field it works fine.

Don't know if this will help:

Code: Select all

guest@porteus:~$ ff='mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%3Fb=FF'
guest@porteus:~$ echo $ff
mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%3Fb=FF
guest@porteus:~$ ls $ff
/bin/ls: cannot access mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%3Fb=FF: No such file or directory
guest@porteus:~$ firefox $ff

(process:3903): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed
^C
Couldn't get error msg. Because of 100% cpu, terminated it.

Look into escape characters. You need to escape the question mark character.

Thank Bogomips. I tried that approach but it didn't get far.

Code: Select all

ff="/mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html?b=FF"
echo $ff
firefox $ff 2>/dev/null &
exit

Code: Select all

guest@porteus:~$ weather.sh
"/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF"
guest@porteus:~$ weather.sh
/mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html?b=FF
And while the variable works FireFox doesn't like it still.

I tried \? and '?' brokenman but that didn't work either.

Your example uses double quotes ("). How about single quotes (') as in my example?

Have script problem somewhat similar to yours. Can get blanks through, but special characters a barrier so far.

Code: Select all

guest@porteus:~$     ff='/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF'
guest@porteus:~$     echo $ff
/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF
guest@porteus:~$     echo "$ff"
/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF
Another variant: firefox "$ff" 2>/dev/null &

guest@porteus:~$ weather.sh
/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF
And the FF URL result is the same.

Code: Select all

file:///mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%3Fb=FF
In that the echos work OK I'm leaning more toward this being a Linux/Porteus FireFox problem.

I gave up and took a different approach to resolve the problem. I tried ", ', \, \x3F in various combinations and none worked. So I changed the webpage's html code.

Code: Select all

 var _parm = location.href;
 var _parm = _parm.indexOf("?");
 if (_parm != -1) {
    _url = 'USNY1645.xml';
 }
 if (navigator.appName == "Netscape") {
    _url = 'USNY1645.xml';
 }
It no longer needs a start parameter when run in Firefox. I hope that option is available to you also Bogomips.

Hi Ed_P

My script is not to do with FF, but with splitting up big movie files for the cloud.

Also of that opinion.

Looks like we've been going round the houses. This is URL format:

Code: Select all

file:///mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%3Fb=FF
This is same URL decoded:

Code: Select all

file:///mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF
Yesterday tried:

Code: Select all

guest@porteus:~$ ff='/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF'
guest@porteus:~$ echo $ff
/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF
firefox $ff
FF decided to create a URL like so: http://www.mnt.com/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF
Today did:

Code: Select all

guest@porteus:~$ ff='/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF'
guest@porteus:~$     echo $ff
/mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF
guest@porteus:~$ firefox "$ff"
and got something else:

Code: Select all

file:///mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%3Fb=FF

File not found

Firefox can't find the file at /mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html?b=FF.
However sometimes a distinction has to be made between CLI in interactive mode and in a script, batch mode, as sometimes programs behave differently depending on the mode.

Code: Select all

guest@porteus:~$ firefox -h

(process:2854): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed
Usage: firefox [ options ... ] [URL]
FF expects a URL. However before surmising a FF defect, FF has to be invoked with a proper URL, where special characters are properly encoded, as opposed to what goes in the navigator bar.

Code: Select all

ff='file:///mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%3Fb=FF'
firefox "$ff"
End of Story. ;)

Firefox can't find the file at /mnt/sda5/Users/Ed/My Webpages/EdsxoapWeatherData.html%3Fb=FF.
And FF's URL box shows:

Code: Select all

file:///mnt/sda5/Users/Ed/My%20Webpages/EdsxoapWeatherData.html%253Fb=FF
What makes this even more interesting, the "?b=FF" URL doesn't work in Internet Explorer either. Remove the "?b=FF" and the URL works fine in IE. :shock:
