When extra impressive business enterprise-oriented microcomputers arrived with CP/M and afterwards DOS pcs like the IBM Computer, the command line began to borrow some of the syntax and features of your Unix shells for instance globbing and piping of output.
A great deal less difficult and a lot more practical was an overhead wire in combination which has a pantograph borne because of the motor vehicle and pressed at the line from down below.
The wiring in most countries is just too lower to permit double stack container trains. The Channel Tunnel has an prolonged top overhead line to support double-height vehicle and truck transporters.
Programs just like the OS/2 E editor and some other IBM editors, can procedure command lines Usually meant for the shell, the output being placed directly in the document window.
This portion requirements enlargement with: more information about other sorts of catenary wire in other nations. You may also help by adding to it. Appropriate dialogue could be observed on the chat web site. (June 2024)
