POSIX

POSIX, akronüüm ingliskeelsest nimetusest Portable Operating System Interface,^[1] on porditava operatsioonisüsteemi IEEE-standard rahvusvahelise standardi koodiga ISO/IEC 9945. POSIX-i standard arenes välja UNIX-ist.

Linuxi arendamisel arvestatakse ühilduvust POSIX-i standardiga, kuid ühilduvust enamasti ei testita, sest testimine ja sertifitseerimine on kulukas. ^[2]^[3] Leidub erijuhtumeid (kriitilistes valdkondades), kus vastavust on sertifitseeritud. LINUXi jaoks on ISO standardid, mis põhinevad POSIX-i standardil.
