NoPrompt Patterns

Option 'P' --> Noprompt, Patterns from Std Input. Normally QTGrep reads the search pattern from either the command line or a pattern file specified via the 'f' option. In some cases, the user may desire to read the search patterns from the Standard Input File. For example when redirecting or piping them from another application program or typing them at the console. In either case, this option, and the 'p' option, will read the search patterns from the Standard Input File. With this option no prompt is sent to the Standard Error File Before reading from the Standard Input File. This is done so that if the user is activating QTGrep from a batch file or another application program, a custom prompt may be issued if necessary.

An end-of-file, <Ctrl-Z> when input from the keyboard, or a blank line, will terminate the input of search expressions. Note especially that a blank line will terminate the input. The user should be very careful of this restriction and ensure that the redirected or piped input does not contain any unwanted blank lines.

This option cannot be specifed in conjunction with the 'p' option. All search pattern file commands are active as with the 'f' option. See the '-?#' option for an explanation of the search pattern file commands.

Incompatible Options Are:
