Es aconsejable hacer una copia de seguridad y comprobar que funcione antes de continuar de la siguiente forma:
$ cp .local/share/webbrowser-app/history.sqlite .
$ sqlite3 history.sqlite
SQLite version 3.8.5 2014-06-04 14:06:34
Enter ".help" for usage hints.
sqlite> .tables
history
sqlite> .schema history
CREATE TABLE history (
url VARCHAR,
domain VARCHAR,
title VARCHAR,
icon VARCHAR,
visits INTEGER,
lastVisit DATETIME
);
sqlite> .output url.txt
sqlite> select * from history ;
sqlite> .quit
$ cat url.txt
