Re: lug-bg: Little help about sed editor

[boukov@xxxxxxxxxxx (Petko Boukov)]

Vyprosyt ne e za perl, no shte si pozvolja da go probutam tuk, ponezhe sed e edno ot mnogoto neshta, koito perl e 'pogylnal'. Vzeh tova ot perlfaq3, kojto mozhesh da vidish s 'man'. Izpylnjava se napravo ot komandnija red (na edin red).

perl -0777 -pe 's{www.company.com/directory}{site.company.com}gs' some_file > another_file 

Sintaksisyt e pochti syshtijat, no perl pozvoljava da promenjash simvolite, zagrazhdashti regexps i po tozi nachin ne se nalaga da escape-vash slash-ovete i ne se chuvstvash vse edno igraesh hop-stop (klechka naljavo, klechka nadjasno).

Mojat syvet e da zarezhesh taja rabota sys syshtija file. Napravi si ako iskash shell script, kojto proverjava dali komandata se e izpylnila pravilno i ako da - iztriva originalnija file i preimenuva novija. Bezdrugo tova e edinstvenijat nachin. Dali shte stane nevidimo ot teb prez vremenen file ili ti sam shte si go organizirash, rezultatyt e syshtijat.
