Bash : Get the current browser tab - bash

Question

Is there any way to get the current opened tab in a browser (firefox at least) using bash .
In other words, the url of the tab that called the bash script from the file browser (incorporated in that page)

Answer 1

Firefox changed the way it stores urls on the hard drive in version 33.
I wrote this php script to search for opened tabs. I used php, so you'll need php5-cli (or newer) package installed.
You'll need to ajust the $displayOnlyLastActiveUrl to fit your needs: set to false to display all opened url, true for last active opened URL
the script might need to be improved, but it fits my needs.
known limitations:
migth not look in the good profile if you have multiple profiles set in firefox.
might takes up to 10 seconds to update
if you choose to output all urls, some closed tabs may appear
just create a php file with the above content and run it within shell with php yourfile.php
<?php

// Display curent opened URLs in firefox.

$displayOnlyLastActiveUrl=true; //set to false to display all opened url, true for last active opened URL
//Search for restore.js (might need to be improved for multiprofiles environement...)
if (!$profileIniContents=fopen(getenv("HOME")."/.mozilla/firefox/profiles.ini", "r")) trigger_error("unable to open profiles file", E_USER_ERROR);
$profile="";
$ar_match=array();
while ($ligne=fgets($profileIniContents))
if (preg_match("/Path=([^.]*)[.]default/", $ligne, $ar_match))
$profile=$ar_match[1];
//Open recovery.js file
if(! $recoveryFileHandle=fopen(getenv("HOME")."/.mozilla/firefox/$profile.default/sessionstore-backups/recovery.js", "r")) trigger_error("unable to open recovery.js file", E_USER_ERROR);
$recoveryData=json_decode(fread($recoveryFileHandle, 4000000), true);
//parse data
$ar_tabs=array();
foreach ($recoveryData["windows"] as $actWindow)
foreach ($actWindow["tabs"] as $actTabGroup)
{
$lastAccess=$actTabGroup["lastAccessed"];
foreach ($actTabGroup["entries"] as $actTabEntry)
if(!$displayOnlyLastActiveUrl) echo($actTabEntry["url"]."\n");
else $ar_tabs[$lastAccess]=$actTabEntry["url"];
}
//search last URL
if ($displayOnlyLastActiveUrl)
{
ksort($ar_tabs);
echo array_pop($ar_tabs);
}
?>

I've found this by chance :
#!/bin/bash
for var in "$#"
do
#
#
done
$# contains the url of the tab.
