1. Temel Kavramlar: Bash ve Alt Dize \u0130\u015flemleri<\/strong><\/p>\n

Bash, Unix tabanl\u0131 i\u015fletim sistemlerinde kullan\u0131lan g\u00fc\u00e7l\u00fc bir komut yorumlay\u0131c\u0131s\u0131d\u0131r. Metin i\u015fleme konusunda olduk\u00e7a yeteneklidir ve \u00e7e\u015fitli ara\u00e7lar kullanarak alt dize i\u015flemlerini kolayca ger\u00e7ekle\u015ftirebiliriz. Bu ara\u00e7lar aras\u0131nda cut<\/code>, sed<\/code>, awk<\/code> ve parametre geni\u015fletme gibi y\u00f6ntemler bulunur. Bu y\u00f6ntemlerin her birinin kendine \u00f6zg\u00fc avantajlar\u0131 ve dezavantajlar\u0131 vard\u0131r ve hangi y\u00f6ntemi se\u00e7ece\u011finiz, verilerinizin yap\u0131s\u0131na ve performans gereksinimlerinize ba\u011fl\u0131d\u0131r.<\/p>\n

Alt dize, bir dizenin bir par\u00e7as\u0131d\u0131r. Belirli bir karakterden \u00f6nceki alt dizeyi \u00e7\u0131karmak ise, hedef karaktere kadar olan b\u00f6l\u00fcm\u00fc ay\u0131klama i\u015flemidir. \u00d6rne\u011fin, “fatihsoysal@example.com” dizisinde “@” karakterinden \u00f6nceki alt dize “fatihsoysal” d\u0131r.<\/p>\n

2. Bash’te Alt Dizeyi \u00c7\u0131karma: Yeni Ba\u015flayanlar \u0130\u00e7in Ad\u0131m Ad\u0131m K\u0131lavuz<\/strong><\/p>\n

Bu \u00f6rnekte, %.*<\/code> parametre geni\u015fletmesi, dizinin sonundaki “.” ve sonras\u0131ndaki t\u00fcm karakterleri kald\u0131r\u0131r.  Daha basit bir yakla\u015f\u0131m ise cut<\/code> komutudur:<\/p>\n
echo "fatihsoysal.txt" | cut -d '.' -f 1<\/code><\/pre>\n
Bu komut, “.” karakterini ay\u0131r\u0131c\u0131 (-d '.'<\/code>) olarak kullan\u0131r ve ilk alan\u0131 (-f 1<\/code>) ekrana yazar.<\/p>\n

Bu log dosyas\u0131ndan sadece tarih bilgisini ay\u0131klamak i\u00e7in awk<\/code> komutunu kullanabiliriz:<\/p>\n
awk '{print $1}' log_dosyasi.txt<\/code><\/pre>\n
Bu komut, her sat\u0131r\u0131 bo\u015fluklara g\u00f6re ay\u0131r\u0131r ($1<\/code> ilk alan\u0131 temsil eder) ve sadece tarih bilgisini yazd\u0131r\u0131r.  Daha spesifik bir ay\u0131r\u0131c\u0131 kullanmak isterseniz -F<\/code> se\u00e7ene\u011fini kullanabilirsiniz:<\/p>\n
awk -F ' ' '{print $1}' log_dosyasi.txt<\/code><\/pre>\n
Bu, bo\u015flu\u011fu ay\u0131r\u0131c\u0131 olarak belirtir.  Performans optimizasyonu i\u00e7in awk<\/code>‘\u0131n tek sat\u0131rl\u0131k i\u015flemler i\u00e7in daha verimli oldu\u011funu unutmay\u0131n.<\/p>\n

echo "fatihsoysal@example.com" | sed 's\/@.*\/\/'<\/code><\/pre>\n
Bu komut, “@” karakterinden sonraki t\u00fcm karakterleri (“@.*”) bo\u015f bir dizeyle de\u011fi\u015ftirir (\/\/<\/code>), b\u00f6ylece sadece “fatihsoysal” kal\u0131r.<\/p>\n

Daha b\u00fcy\u00fck dosyalarla \u00e7al\u0131\u015f\u0131rken performans \u00f6nemlidir.  xargs<\/code> komutu ile cut<\/code> veya awk<\/code> komutlar\u0131n\u0131 birle\u015ftirerek performans\u0131 art\u0131rabilirsiniz.  A\u015fa\u011f\u0131daki \u00f6rnekte, b\u00fcy\u00fck bir dosyadan belirli bir karakterden \u00f6nceki alt dizeleri ay\u0131klamak i\u00e7in xargs<\/code> kullan\u0131lm\u0131\u015ft\u0131r:<\/p>\n
cat b\u00fcy\u00fck_dosya.txt | xargs -n 1 bash -c 'echo "$1" | cut -d ":" -f 1'<\/code><\/pre>\n
Bu komut, her sat\u0131r\u0131 ayr\u0131 bir bash<\/code> i\u015flemine g\u00f6ndererek paralel i\u015fleme sa\u011flar.

B\u00fcy\u00fck dosyalar i\u00e7in awk<\/code> veya perl<\/code> gibi daha g\u00fc\u00e7l\u00fc ara\u00e7lar daha uygun olabilir.  awk<\/code>‘\u0131n substr()<\/code> fonksiyonu da kullan\u0131labilir:<\/p>\n

Bu komut, sat\u0131r\u0131n ba\u015f\u0131ndan (@ i\u015faretinin indeksinden 1 eksik kadar olan k\u0131sm\u0131n\u0131 yazd\u0131r\u0131r.<\/p>\n
6.  Edge Case’ler ve Hata Y\u00f6netimi (\u0130leri D\u00fczey)<\/strong><\/p>\n
Hedef karakterin bulunmad\u0131\u011f\u0131 durumlar gibi edge case’leri ele almal\u0131y\u0131z.  \u00d6rne\u011fin,  “@”” karakteri olmayan bir e-posta adresi i\u00e7in kodumuzun nas\u0131l davranaca\u011f\u0131n\u0131 d\u00fc\u015f\u00fcnmeliyiz.  Hata y\u00f6netimi i\u00e7in if<\/code> ko\u015fullar\u0131 kullanabiliriz:<\/p>\n

Bu kod, “@”” karakterinin olup olmad\u0131\u011f\u0131n\u0131 kontrol eder ve buna g\u00f6re i\u015flem yapar.<\/p>\n
