| | Unix - Wikipedia, the free encyclopedia |
 | | In an effort towards compatibility, several Unix system vendors agreed on SVR4's ELF format as standard for binary and object code files. |
 | | There were no "binary" editors in the original version of Unix - the entire system was configured using text shell commands and the least and greatest common denominator in the I/O system is the text byte - unlike "record-based" file systems in other computers. |
 | | Its own kernel development project, GNU Hurd, had not produced a working kernel, but a compatible kernel called Linux was released as free software in 1992 (under the GNU General Public License). |
