Full Discussion: Using output to input another command

Tools Use a for loop
#! /bin/bash

for zf in *myfile*.*
do
ls -l $zf
tail $zf
done

Notes:
(1) I do an ls command; not needed - just shows what file is being looked at in the loop
(2) tail is its own command line since guess you want to do more than simply execute this one command

This could all be done in one line as:
tail *myfile*.*
but, I figure this is part of something more complicated.
So, two choices.

kaptain

KAPTAIN(1)						      General Commands Manual							KAPTAIN(1)

NAME

       kaptain - Universal graphical front-end for command-line programs.

SYNOPSIS

       kaptain [options] file

DESCRIPTION

       kaptain reads the given file and builds a user-friendly dialog according to the grammar rules found in it.

       See info kaptain for a detailed overview.

OPTIONS

       kaptain accepts the following options:

       -h, --help
	      Show summary of options.

       -V     Run in verbose mode.

       --version
	      Show version of program.

       --test Run in test mode. This means that commands are not executed when a button is pressed, only printed to the standard output.

       -V, --verbose
	      Report  more  information  on processing the input file. Internal representation of the grammar and the dialog tree is also printed.
	      Use this flag if Kaptain does not work as expected.

       -c <host:port>, --client <host:port>
	      Establish communication channel as a client connecting to a server on <host> listening on <port>.

       -s <port>, --server <port>
	      Listen to the specified <port> and accept the first connection. This will be used as a communication channel.

       -p <command>, --pipe <command>
	      Start the given command and communicate with it on its standard input and output. Don't forget to quote  <command>  if  it  contains
	      spaces or other metacharacters used by the shell.

       --stdio
	      Use  standard  input  and  output for communication. In this case you must specify an input file, thus grammar script cannot be read
	      from the standard input when it is used as a communication channel.

       --no-input
	      Instructs Kaptain not to process messages received on the input channel.

       --no-output
	      If this flag is set, Kaptain will not send any messages on its output channel.
