Doing a tail in a script and then return back and continue script
Hello all,

I am trying to do a tail in a script. But when I quit the tail my script quits also. This is not what I want. I am struggling to get this done.

PHP Code:
#!/bin/bash
 
askFile() {
  echo -n "Enter file: "
  read FILE
}
 
doTail() {
  tail -F "${1}"
}
 
askFile
doTail "${FILE}"
askFile
doTail "${FILE}" 
Above is just a simple example what I am trying to do. As you see I first ask for a file. Then I do a tail on this file. If you now quit the tail by entering CTRL+C the total script stops. But I want it to ask for a file again.

Does anyone know how to do this?

Thanks in advance for any help.

Mark

inotail

INOTAIL(1)						       Inotify enhanced tail							INOTAIL(1)

NAME

       inotail - A fast and lightweight version of tail using inotify

SYNOPSIS

       inotail [OPTION]... [FILE]...

DESCRIPTION

       inotail	is a replacement for the 'tail' program found in the base installation of every Linux/UNIX system. It makes use of the inotify in-
       frastructure in recent versions of the Linux kernel to speed up tailing files in the follow mode (the '-f' option). Standard tail polls the
       file every second by default while inotail listens to special events sent by the kernel through the inotify API to determine whether a file
       needs to be reread. Note: inotail will not work on systems running a kernel without inotify. To enable inotify, please set CONFIG_INOTIFY=y
       in your Linux kernel configuration and recompile it.

       Currently inotail is not fully compatible to neither POSIX or GNU tail but might be in the future.

OPTIONS

       -c N, --bytes=N
	      output the last N bytes. If the first character of N is a '+', begin printing with the Nth character from the start of each file.

       -f, --follow
	      keep the file(s) open and print appended data as the file grows

       -n N, --lines=N
	      output  the last N lines (default: 10) If the first character of N is a '+', begin printing with the Nth line from the start of each
	      file.

       -v, --verbose
	      print headers with file names

       -h, --help
	      show help and exit

       -V, --version
	      show inotail version and exit
