shebang

Hisoblashda shebang - satr avvalida panjara va undov birga yoziladigan unix uslubiyati (#!). Shuningdek, u o'tkir undo, sha-bang,[1][2] hashbang,[3][4] pound-bang,[1][5] yoki hash-pling deb ham ataladi.[6][7]

Shebang bilan matn faylini Unixga oid operatsion tizimda ishga tushirishda, dastur yuklovchi mexanizm faylning qolgan boshlang'ich satrini tarjimon yo'l-yo'riq sifatida tahlil qiladi. Yuklovchi belgilangan tarjimon dasturini bajaradi va dastlab skriptni ishga tushirishga harakat qilish paytida foydalanilgan yo'lni argument sifatida unga o'tkazadi, shunda dastur faylni kirish ma'lumotlari sifatida ishlatishi mumkin. [8] Masalan, agar skript yo'l path/to/script bilan belgilangan bo'lsa va satr #!/bin/sh/bin/sh shaklida boshlansa, dastur yuklovchiga dasturi /bin/ish, o'tish yo'li /to/script birinchi argument sifatida ishga tushirish uchun qoʻllanadi.
