Zdravei,

Ne sym v chas mnogo tochno sys sed, no
 
ako e samo za '/' izpolzvai:

's/www.company.com\/support/support.company.com/gw output' input 

ne vsichki sed versii shte ti pozvolqt da pravish write v syshtiq file,
pone gnu sed 3.02 se pravi na devica (kraen rezultat - truncate).

Tova gornoto moshe da go napravish i na Perl dosta po gyvkavo kato:

/(\w+).company.com\/(\w+)/$2.company.com/g;

primerno. (kakto i po dosta drugi nachini)

Vyobshte edin bezplaten syvet - ako iskash da polzvash regex functions za
stream operacii, po-dobre zabravi za sed, izpolzvai awk ili perl.

... i RTFM. :-)

Shiv i zdrav.

Cheers,
atanas argirov
