Opis

Potrzebowałem pakować dema do Deathmatch Classic. Zapomniałem go tu wrzucić.

• daje możliwość tez automatycznego pakowania i segregowania dem wg daty rok/miesiac/dzien
• nie pakuje aktualnie nagrywanych dem
• nie usuwa źle spakowanego dema (np jak sobie dysk zapchasz :) )
• może usuwać stare spakowane dema, np starsze niż 14 dni
• przy niewielkiej modyfikacji moze tez wywalac logi

Parametry w konfiguracji, linia po linii (bez komentarzy):

• konfiguracja ścieżki w której znajduje się skrypt (WORKDIR)
• konfiguracja gdzie znajdują się dema do spakowania (SRCDIR)
• ścieżka gdzie zapisywać dema w formacie (DSTDIR)/rok/miesiac/dzien/
• wzorzec rozpoznawania dem, domyślnie hltv*.dem
• wzorzec rozszerzenia nazwy pliku dem - tego lepiej nie ruszaj
• wybór pakera, domyślnie tar
• opcje pakera, domyślnie dla bzip2
• rozszerzenie pakowanego dema, domyślnie tar.bz2
• plik tymczasowy do listy plików do spakowania
• log z wykonanych operacji
• ustawienie priorytetu aby nie zamulać procka (NICE)
• opcja kasacji starych spakowanych dem DELETE_OLD
• spakowane dema starsze niż X dni są kasowane (domyślnie 14)

Do crona wpisać cos w ten deseń:

20 5 * * * /home/hlds/scripts/pack_demos.sh > /home/hlds/scripts/pack_demos.cron.log 2>&1

Jak włączysz mózg i poczytasz manuala to dostosujesz do dowolnego packera i pakowania dowolnie pojawiających się cyklicznie plików (chociażby log, aczkolwiek tutaj lepiej byłoby pakować logi dniami a nie każde osobno)

Kod

# _KaszpiR_ kaszpir@gmail.com
# Script to find and pack HLTV demos
# if you want to change it to something else you must edit awk lines where the year/month/day is extracted from filename
#
# run program with any parameter to see the list of  files that will be processed
#
# Changelog:
# ver 1.3 2011.01.20, 14:16 
# + added basic checks to avoid error configurations, should be really more
# + running script with any parameter will show command and will require pressing any key to continue
# + added quotation marks in some places to allow specific name patterns
# ver 1.2 2011.01.16, 15:15 
# + added ftp upload
# + all variables curly brackets for security reasons
# + listing old files is potional
# + added hashes on output lines for easier parsing
# ver 1.1 2009.08.31
# + added option to list directories for deletion older than X days
# + added definiton for the extension files

Info

No dobra, jak ktoś przeczytał kod to się pewnie kapnął że nie będzie kasowanych katalogów ze starymi spakownaymi demami, bo jest komenda echo a nie rm -rf

Tyle, że trzeba BARDZO uważać co się będzie kasować, dlatego dałem echo.
