Když to v bash-i ulítne - výběr komprimační metody

Když to bash-i ulítne. Kdo někdy programuje, tak to zná: „jen si tady něco vyzkouším na, to je prkotinka v bash-i na 10 řádků“.
Jenže ta prkotina dává nějaké informace, které chceme rozvíjet a tak je rozvíjíme, a už při délce 20 řádků začíná být jasné, že zvolený nástroj, tedy bash, není to nejlepší, ale pokračujeme…
…přece vím(e): „Jo je to naprd, bude to sice trvat 3× déle, ale když už to mám(e), přece nebudeme začínat od začátku“. A najednou tu máme 1500 řádků.
No a přesně to se mi opět stalo.
Řešil jsem už po několikáte situaci jakou komprimaci na data zvolit.
Ve spoustě případů je to fuk, a je to zbytečné to řešit - místa je dosta a je snažší navýšit kapacitu. Někdy to naráží „zlom“ (více disků se tam nevleze a pod…) a když už, tak to udělat pořádně.
bzip2 -9 je sem-tam horší než bzip2 -5, stane se i, že je gzip na tom lépe než bzip2, záleží na typu dat.
Takže když to člověk chce pořádně, tak si to zkusí a pak to aplikuje, ale ono je to docela opruz. Tak jsem si říkal, že bych si mohl udělat takový testík, který to zkusí a vyhodnotí (hlavně druhá část byla velká chyba, na to je přece tabulkový procesor).
Řešil jsem už v zásadě 3 situace:

1. All-in-one co nejmenší. Normální archiv či záloha maximálně zkomprimovaná.
2. Jednotlivé soubory, každý komprimovaný zvlášť (stejným typem komprese). Konkrétní případ nebudu popisovat, ale lze to přirovnat k úložišti RAW-ů (fotek), kde jsou vygenerované náhledy a je jich smečka. Každý zvlášť chceme proto, že jej chceme rychle získat, nejen rozbalit, ale i přenést.
3. Jednotlivé složky obsahující roj dat, každá komprimovaná zvlášť. Co složka to zakázka s velkým objemem různých dat, po určité době není třeba mít data ihned po ruce, ale běžně dostupné. Jejich komprimace + přenastavení práv archivu, hezky řeší situaci, rychle a kompaktně lze data získat a zabírají méně místa.

No jak šel čas, tak mi z toho vylezl tento „skriptík“, jistě obsahující spoustu chyb, někté označené jako vlastnost.

Běžné spuštení pro test souborů všemi metodami a jejich kombinacemi:
find /absolute/path/dir -type f | ./comptest.bash -v -n 42 -w /absolute/path/to/save/dir/result.res -f

Běžné spuštení pro test adesářů (které si zataruje), jen compresí gz -9, bz-9 a 7z může vypadat nějak takto:
find /absolute/path/dir -mindepth 1 -maxdepth 1 -type d | ./comptest.bash -v -n 'e0 1 4' -w /absolute/path/to/save/dir/result.res -d

A případné opakované zobrazení výsledků:
./comptest.bash -o /absolute/path/to/save/dir/result.res
nebo
./comptest.bash -o -R 0.8 -S 8388608 /absolute/path/to/save/dir/result.res

Pro vytvořeni a uchování nejmenšího archivu:
./comptest.bash -t /directory/to/save/ -T noexistsdirname -L -n allbest1 -f /full/file/path/name
nebo pro tar adresáře
echo /full/dir/path/name | ./comptest.bash -t /directory/to/save/ -T noexistsdirname -L -n allbest1 -d

…si to vytvoří pomocnou složku (v /tmp , přestavit lze pomocí -t), kam si každý zadaný úkol připraví a otestuje (v případě -L, -l i archiv-y zanechá).
V případě úkolu 'po souboru' (-i nebo -f) si bere soubor, v případě adreářů (-d) si vytvoří tar ze zadaného adresáře. Zvláštností je, že každý cesta MUSÍ být zadána plná-absolutní (to není bug to je právě feature).
Umí to vybrat a zanechat nejmenší archiv (-L) nebo případně i všechny (-l). U menších dat nemusí být tak důležitá velikost, ale kolik zabírají bloků, což lze zadat (-b), někdy máme předvolený čas (server se třeba v noci fláká) nebo nás zajímá kompresní poměr, tak je lze zadat (-S -R) a v grafu se pak objeví jako dvojtečkovaná či tildová čára.
Výsledky si lze uložit do souboru (-w) a pak opět načíst (-o), ale nelze pak už změnit velikost bloku…
-w je dobré použít, uloží to údaje po každém testovaném soouboru a tedy i když se to pak zeštřelí, bo nás už nebaví na to čekat, tak něco z toho je.
(Pokud se to udělá kill <PID toho testu>, snad se to zestřelí až po skončení právě testovaného souboru - po všech vybraných kompresích.)

Tady je pár zbytečností či zajímavostí, ke ketrým jsme došel.

Výsledek z různých specifckých dat (80 adresářů/vzorků celkem do 15GiB), kde 20 % dole považuji za účelné (rcyhlost není důležitá, ale je hezky vidět jak je gzip rychlý):

Jinak na VMWare adresáře virtuálních strojů je 7z i 10 % efektivnější než bz2 či gz.

Když nic, tak jsem si opět připoměl, že minimálně za − (minus) pro bc je vhodné dávat mezeru, protože XY=-5; echo "10-${XY}" | bc to nesežere.

A fčul hurá na bramborový salát… (vyrobit, ne zlikvidovat…)

Jinak na VMWare adresáře virtuálních strojů je 7z i 10 % efektivnější než bz2 či gz.

Jestli si dobre pamatuju, tak je to tim ze 7z u kazdeho souboru testne jestli nejsou komprimovana data delsi nez nekomprimovana a pokud jo, tak ulozi do archivu ty nekomprimovana. Takze pokud je tam smeska ruznych typu souboru, muze to mit velmi pozitivni ucinek na vyslednou velikost.

[Radovan Garabík]

Zaujímavé by bolo porovnať aj rzip, prípadne lrzip (a možno aj xz/lzip, ale tam budú asi výsledky o niečo horšie ako 7zip)

[Šangala]

Asi je to zajímavá myšlenka (jsem to doplnil - ten script, kdyby to někdo chtěl, tak sem dám znovu),

7zip soubory zvětšuje

[w4rr10r]

Nevím, kdo tě učil skloňovat, ale nenaučil tě to. "bash-i" apod. fakt není dobře.

[Šangala]

Vidiš a já su přesvědčený, že je…

[w4rr10r]

Jistě to podpoříš argumentem, a sice nejlépe odkazem na výjimku z pravidel českého pravopisu, která o takové grafické úpravě skloňování přejatých slov a jmen hovoří. Tvrdím, že taková úprava nejen neexistuje, ale navíc to vypadá nechutně.

[Šangala]

Nepodpořím. A je mi jedno co existuje či neexistuje, přijde mi to jako nejlepší kompromis a nyní je na pravidlech, aby se do mé úpravy vyvinula ;). Sice mě mrzí, že Tě to irituje, za což se Ti omlouvám, ale s trochou tolerance nebo ignorace to lze zvládnout…

[falešný amig4poשer]

Taková úprava existuje, stačí si přečíst tento blog. A nechutnej seš ty, tak neremcej :)

[Josef Kufner]

Tyhle věci se nechávají bez skloňování. Stejně jako například číslovky psané číslicemi.

[imploder]

Jako že správně by to mělo být všude v 1. pádě (v bash)? To mi teda rozhodně správné nepřipadá.

[jekub]

můžete o tom pochybovat, můžete proti tom protestovat, ale ...

[Václav HFechs Švirga]

Souhlasím, možná je to správné, ale zato dementní (dle mého názoru) . Kdo nehrotí normy a netrápí ho pohoršené pohledy puristů, nemá problém . Ale napsal bych v bashi.

[Xerces]

Ne. Správně by mělo být ... v bashu ... protože BASH = Bourne-Again SHell a tedy v Bourne-Again SHellu. :-]

[tom]

Zkratkovita slova se nezklonuji podle posledniho slova zkratky, doporucuji vyzkouset na Cedoku

[falešný amig4poשer]

Toš ty jako správný moravák byz měl vědět, že správně je "v bash-u"

[Šangala]

Toš to su a vím to, ale bárgde by tomu nerozuměli
