No. It is not clear.
  1. What operating system are you using?
  2. What shell are you using?
  3. How is DIR defined?
  4. How is myfile defined?
  5. How do you determine if a line in $myfile matches the user input?
  6. How is the user input accessed in your program? (Command line argument? Command line option? String read from a file? String prompted for and read from standard input? ...?)
  7. Rather than just showing us code that is not working, describe what you are trying to do with foreach ($PxyType in "${DIR}"/"File.json").
  8. You have said you want to produce thousands of files named File1,2,3..json and *.json. Both of these specifications are ambiguous. What filenames are you trying to produce?
Please show us small, representative sample input files (using CODE tags), sample input the user might supply (using CODE or ICODE tags), and the names and contents of the output files that should be created from those sample inputs (using CODE tags).

DESCRIPTION

       The flow-split utility will split a flow file into smaller files based on the the number of flows or the ammount of time that has passed.

       -N nflows Split after processing nflows.

       -o outfile_basename
		 The basename of the resulting files.

       -T nsecond
		 Split after processing an interval of nseconds flows.

       -z z_level
		 Configure compression level to  z_level.  0 is disabled (no compression), 9 is highest compression.

EXAMPLES

       Create 1 minute flow files from the flow archive in /flows/krc4.  Store the results in /flows/krc4.split

	 flow-cat /flows/krc4 | flow-split -T60 -o /flows/krc4.split/1min.
