Opera initialization script (О гуру bashскриптинга, объясните!)

Makinos · Сообщение **Makinos** » 01.09.2009 07:09

было установлено 2е разные версии Оперы (с двумя разными профилями)- одна пакетным менеджером (дефолтная), другая в папке валялась в /home

Если запускать из терминала ту что в /home с помощью скритпа инициализации, то она и запускалась, а если какой-нить командой (из другого скрипта или приложения)- то вместо нее запускалась уже дефолтная! Как же млин так??
Кто-нить может объяснить, почему?

Я уже пробовал запускать и не exec`ом, а из дочернего процесса (типа fork) и чего только не пробовал

но ничего не изменилось.

Вот сам оперный скрипт инициализации:

Не очень понятно, какое отношение вопрос имеет к программированию...

Видимо, 'дефолтная' опера у вас в $PATH (что логично), в отличие от той что в /home (что тоже логично). Поэтому команда `opera' запускает дефолтную оперу, в отличие от скрипта, который запускает /home/.../usr/lib/opera/opera.

Потому что

Код: Выделить всё

which opera

киньте симлинк в /usr/local/bin на вашу оперу в хоме

Код: Выделить всё

ln -s /home/user/opera/opera /usr/local/bin/opera

Я идиот!!!
Я забыл, что в /usr/bin тоже есть линк или скрипт "opera"...

Не очень понятно, какое отношение вопрос имеет к программированию...

Спасибо, я уже понял, что никакого
