Iqokobhe elingu C ngumqhubekekisi womyalelo oqhele ukwenziwa kwifestile yokubhaliweyo, evumela umsebenzisi ukuchwetheza imiyalelo.
Yintoni iqokobhe leKorn kwiLinux?
Iqokobhe leKorn liqokobhe leUNIX (inkqubo yophumezo yomyalelo, edla ngokubizwa ngokuba yitoliki yomyalelo) eyathi yaphuhliswa nguDavid Korn weBell Labs njengoguqulelo olubanzi oludityanisiweyo lwamanye amakhulu amaqokobhe eUNIX. Ngamanye amaxesha eyaziwa ngegama lenkqubo ksh , iKorn liqokobhe elingagqibekanga kwiindlela ezininzi ze UNIX.

- Bhala iskripthi kwifayile usebenzisa umhleli.
- Yenza okushicilelweyo kuphunyezwe ngomyalelo chmod +x .
- Sebenzisa iscript usebenzisa ./ .
Lisebenza njani iqokobhe le-Unix?
