Intermediate Sed: Linux Ortam\u0131nda Metin Ak\u0131\u015flar\u0131n\u0131 Manip\u00fcle Etmek<\/h2>\n

Linux ve UNIX benzeri sistemlerde metin i\u015fleme, g\u00fcnl\u00fck sistem y\u00f6netimi g\u00f6revlerinden karma\u015f\u0131k veri analizine kadar pek \u00e7ok alanda temel bir ihtiya\u00e7t\u0131r. Bu ba\u011flamda, sed<\/code> (Stream Editor) komutu, metin ak\u0131\u015flar\u0131n\u0131 sat\u0131r sat\u0131r i\u015fleyerek d\u00f6n\u00fc\u015ft\u00fcrme, filtreleme ve d\u00fczenleme yetene\u011fiyle \u00f6ne \u00e7\u0131kan g\u00fc\u00e7l\u00fc bir ara\u00e7t\u0131r. \u00c7o\u011fu kullan\u0131c\u0131 sed<\/code>‘in temel ikame (s<\/code>) ve silme (d<\/code>) komutlar\u0131n\u0131 bilse de, bu makale sed<\/code>‘in daha derinlemesine \u00f6zelliklerini, ak\u0131\u015f kontrol mekanizmalar\u0131n\u0131, geli\u015fmi\u015f adresleme y\u00f6ntemlerini ve karma\u015f\u0131k metin manip\u00fclasyonlar\u0131 i\u00e7in nas\u0131l kullan\u0131labilece\u011fini ke\u015ffedecektir. Amac\u0131m\u0131z, sed<\/code>‘i yaln\u0131zca basit bir arama-de\u011fi\u015ftirme arac\u0131 olmaktan \u00e7\u0131kar\u0131p, ger\u00e7ek bir programlama dili gibi kullanabilen, metin ak\u0131\u015flar\u0131 \u00fczerinde tam kontrol sahibi bir kullan\u0131c\u0131 profili olu\u015fturmakt\u0131r.<\/p>\n

Ayr\u0131ca, sed<\/code>‘i di\u011fer Linux ara\u00e7lar\u0131yla birle\u015ftirerek daha g\u00fc\u00e7l\u00fc \u00e7\u00f6z\u00fcmler \u00fcretme yollar\u0131na ve yayg\u0131n hatalardan ka\u00e7\u0131nma ipu\u00e7lar\u0131na da de\u011finece\u011fiz. Bu yolculu\u011fun sonunda, sed<\/code>‘in ger\u00e7ek g\u00fcc\u00fcn\u00fc ke\u015ffetmi\u015f ve metin i\u015fleme becerilerinizi bir \u00fcst seviyeye ta\u015f\u0131m\u0131\u015f olacaks\u0131n\u0131z.<\/p>\n

Sed’in Temellerini Hat\u0131rlayal\u0131m<\/h3>\n

sed<\/code>, bir giri\u015f ak\u0131\u015f\u0131ndan (dosya veya boru hatt\u0131) okunan metin sat\u0131rlar\u0131 \u00fczerinde belirtilen i\u015flemleri ger\u00e7ekle\u015ftiren do\u011frusal bir metin d\u00fczenleyicidir. Her sat\u0131r\u0131 okur, \u00fczerinde komutlar\u0131 uygular ve varsay\u0131lan olarak standart \u00e7\u0131kt\u0131ya yazar. Temel s\u00f6zdizimi \u015f\u00f6yledir: sed [SE\u00c7ENEKLER] 'KOMUT' [DOSYA...]<\/code>.<\/p>\n

En yayg\u0131n kullan\u0131lan komutlar:
\n* s\/eski\/yeni\/<\/code>: eski<\/code> deseniyle e\u015fle\u015fen ilk ifadeyi yeni<\/code> ile de\u011fi\u015ftirir.
\n* d<\/code>: E\u015fle\u015fen sat\u0131rlar\u0131 siler.
\n* p<\/code>: E\u015fle\u015fen sat\u0131rlar\u0131 yazd\u0131r\u0131r. Genellikle -n<\/code> se\u00e7ene\u011fiyle birlikte kullan\u0131l\u0131r, bu da sed<\/code>‘in varsay\u0131lan \u00e7\u0131kt\u0131s\u0131n\u0131 bast\u0131r\u0131r ve yaln\u0131zca p<\/code> komutuyla belirtilen sat\u0131rlar\u0131 yazd\u0131r\u0131r.<\/p>\n

Adresleme, sed<\/code>‘in hangi sat\u0131rlar \u00fczerinde i\u015flem yapaca\u011f\u0131n\u0131 belirler. Bu, bir sat\u0131r numaras\u0131 (sed '5d' dosya.txt<\/code>), bir adres aral\u0131\u011f\u0131 (sed '5,10d' dosya.txt<\/code>) veya bir d\u00fczenli ifade (sed '\/hata\/d' log.txt<\/code>) olabilir.<\/p>\n
