However, the rest is doable. I'm not giving the best possbile answer because I cannot do that without knowing your system type and your shell.
1. you need to be able to login in to the server
2. you have to be able to write to a file in your home directory or /tmp

Some flavors of Linux example:

Code:

$ sudo apt-get install sshpass   # do this only once
$ sshpass -p your_password ssh user@hostname 'tail -f /path/to/logfile/filename ' > $HOME/somefile  &

The & makes the command run in the background
$HOME/somefile will have the data you want work with
Note that you need to be very specific about what you want to find locally. Please. Give us example input and desired ouput. Also!
Please give us the output of:

uname -a && echo $SHELL

My example DOES NOT work everywhere.

Thanks @Jim for the answer.
I'm a beginner and may not know everything about UNIX commands. My question was just that if there's any way we can download any file to my local system from Putty/WinSCP and that file is in continous update mode (logs are getting written everytime on that file).

I need to highlight ERROR word with red color in that file.
Normally I use tail -f server.log to follow this file, and keep a eye to see for ERROR line. I just want a better UI so that ERROR lines is visible easily.

mtail

MTAIL(1)							   User Commands							  MTAIL(1)

NAME

       mtail - tail variant designed for web developers monitoring logfiles

SYNOPSIS

       mtail [options]	<file>...

DESCRIPTION

       MonkeyTail  allows  a  user to tail multiple files on both local and remote hosts and clearly marks inactivity by putting 5 newlines in the
       output whenever a pause in output over 3 seconds is detected.

       MonkeyTail is implemented a fairly simple wrapper script around standard tail, ssh, and sudo.

OPTIONS

       -q     Quiet mode

       --quiet
	      "    "

       -n     Output the last N lines of each file before tailing (defaults to 0)

       <file>...
	      Files to tail.

	      These can specified in the following ways:

       @<groupname>
	      - expands the group (from .mtailrc) to a list of

	      files to tail

       <filename>
	      - tails a local file.

       +<filename>		- attempts to sudo and tail a local file (will
	      prompt for pwd if required).

       <remotehost>:<filename>
	      - attempts to invoke tail via ssh on a remote

	      host.

       +<remotehost>:<filename> - attempts to invoke sudo tail via ssh on a
	      remote host (will prompt for pwd if required).
