Linux i\u015fletim sistemi, \u00e7ok kullan\u0131c\u0131l\u0131 ve \u00e7ok g\u00f6revli bir yap\u0131ya sahip oldu\u011fundan, sistem kaynaklar\u0131n\u0131n etkin bir \u015fekilde y\u00f6netilmesi b\u00fcy\u00fck \u00f6nem ta\u015f\u0131r. Bu y\u00f6netimin temelini olu\u015fturan kavramlardan biri de “s\u00fcre\u00e7ler”dir. Bir s\u00fcre\u00e7, \u00e7al\u0131\u015fan bir program\u0131n veya komutun bir \u00f6rne\u011fidir ve kendi bellek alan\u0131na, CPU zaman\u0131na ve di\u011fer sistem kaynaklar\u0131na sahiptir. S\u00fcre\u00e7 y\u00f6netimi, sistem y\u00f6neticilerinin ve ileri d\u00fczey kullan\u0131c\u0131lar\u0131n sistem performans\u0131n\u0131 optimize etmesi, sorunlar\u0131 gidermesi ve g\u00f6revleri otomatikle\u015ftirmesi i\u00e7in vazge\u00e7ilmez bir beceridir.<\/p>\n
Bu makale, Linux’ta s\u00fcre\u00e7 y\u00f6netiminin temel prensiplerini ve en yayg\u0131n komutlar\u0131n\u0131 inceleyecektir. S\u00fcre\u00e7leri g\u00f6r\u00fcnt\u00fcleme, kontrol etme, \u00f6nceliklerini de\u011fi\u015ftirme ve otomatik g\u00f6revler olu\u015fturma gibi konular\u0131 ele alarak, Linux ortam\u0131nda s\u00fcre\u00e7ler \u00fczerinde tam kontrol sa\u011flamay\u0131 hedefliyoruz.<\/p>\n
Bir sistem y\u00f6neticisi i\u00e7in, sistemde hangi s\u00fcre\u00e7lerin \u00e7al\u0131\u015ft\u0131\u011f\u0131n\u0131, ne kadar kaynak t\u00fckettiklerini ve hangi durumda olduklar\u0131n\u0131 bilmek, sorun giderme ve performans izleme a\u00e7\u0131s\u0131ndan kritik \u00f6neme sahiptir. Linux, bu bilgileri sa\u011flamak i\u00e7in bir dizi g\u00fc\u00e7l\u00fc komut sunar.<\/p>\n
Komutu \u00e7al\u0131\u015ft\u0131rd\u0131\u011f\u0131n\u0131zda, \u00fcst k\u0131s\u0131mda sistem \u00f6zeti (CPU y\u00fck\u00fc, bellek kullan\u0131m\u0131 vb.) ve alt\u0131nda s\u00fcre\u00e7 listesi bulunur. ps<\/code> (process status) komutu, o anki s\u00fcre\u00e7lerin bir anl\u0131k g\u00f6r\u00fcnt\u00fcs\u00fcn\u00fc (snapshot) alman\u0131z\u0131 sa\u011flar. Varsay\u0131lan olarak, sadece mevcut kabuk oturumunda \u00e7al\u0131\u015fan s\u00fcre\u00e7leri g\u00f6sterir. Ancak \u00e7e\u015fitli se\u00e7eneklerle bu \u00e7\u0131kt\u0131y\u0131 \u00e7ok daha detayl\u0131 hale getirebilirsiniz.<\/p>\nKullan\u0131m\u0131 ve \u00d6nemli Se\u00e7enekler:<\/h4>\n
