Synopsis

scanfile ?-copyfile copyfieId? Contexthandle fileId

Description

Scan the file specified by fileId, starting from the current file position. Check all patterns in the scan context specified by contexthandle against it, executing the match commands corresponding to patterns matched.

If the optional -copyfile argument is specified, the next argument is a file ID to which all lines not matched by any pattern (excluding the default pattern) are to be written. If the copy file is specified with this flag, instead of using the scancontext copyfile command, the file is disasso- ciated from the scan context at the end of the scan.
