Abstract
U2G is a software tool that runs on the GCOS-8 operating system and enables it recognize and process the commonly used commands of the UNIX operating system. U2G is a UNIX-GCOS-8 translator that enables the GCOS-8 to recognize, accept and execute UNIX commands. Thus, it enables the UNIX users to work with the GCOS-8 system without prior training. U2G can translate the most commonly used UNIX commands along with their respective options into equivalent GCOS-8 Time Sharing System (TSS) commands. U2G can be used with a "verbose" mode option which serves to provide descriptive information about the commands and the translation process. The verbose mode is disabled by a "terse" command.
Claims4
An open computer complex comprising:
- A) a first computer system operating under the GCOS-8 operating system having a first operating system command repertoire;
- B) a second computer system operating under the UNIX operating system having a second operating system command repertoire;
- C) at least one of said first computer system and said second computer system further including a user terminal;
- and
- D) interface means connecting said first and second computer systems, said interface means including an operating system translator, said operating system translator comprising:
- 1) a table of equivalent commands which are included in said first operating system command repertoire and said second operating system command repertoire, said table of equivalents including the following equivalent file operating system commands:
- ______________________________________ UNIX GCOS-8 ______________________________________ ls clist cat display more p rm rele mv acce tail tail diff diff file len wc wc sort bsort ______________________________________
- 2) means for receiving an operating system command from said second operating system command repertoire which is to be executed in said first computer system;
- 3) means for determining from said table an operating system command in said first operating system command repertoire which is an equivalent operating system command of said operating system command from said second operating system command repertoire which is to be executed in said first computer system;
- 4) means for executing said equivalent operating system command in said first computer system;
- and
- 5) verbose mode means for selectively displaying on said user terminal messages describing the relationship between said operating system command from said second operating system command repertoire and said equivalent operating system command from said first operating system command repertoire, said verbose mode being invoked by a first manually entered command and disabled by a second manually entered command.
