If you put few commands in a logical sequence in a file and give it execute permissions, then this file becomes a script.

For e.g., you can write a script to forcefully delete all the log files in a directory and notify the user if removal was a success.

Code:

#! /bin/bash
rm -f /my/dir/*.log
if [ $? -eq 0 ]
then
    echo "All log files removed"
else
    echo "Looks like something happened"
fi

Shell script is a script written for a shell. And the shell could be any, depending on the OS you're working on.

Unix script could mean a script written specifically for any of the shells of Unix.

tv_split

TV_SPLIT(1p)						User Contributed Perl Documentation					      TV_SPLIT(1p)

NAME

       tv_split - Split XMLTV listings into separate files by date and channel.

SYNOPSIS

       tv_split --output TEMPLATE [FILE...]

DESCRIPTION

       Read XMLTV listings and split them into some number of output files.  The output file chosen for each programme is given by substitutions
       on the filename template supplied.  You can split listings by time and by channel.

       The TEMPLATE is a filename but substitutions are applied: first %channel is replaced with the id of a programme's channel, and then
       Date::Manip substitutions (which broadly follow date(1)) are applied based on the start time of each programme.	In this way each programme
       is written to a particular output file.	When an output file is created it will also contain all the channel elements from the input.

       One or more input files can be given; if more than one then they are concatenated in the same way as tv_cat.  If no input files are given
       then standard input is read.

EXAMPLE

       Use "tv_split --output %channel-%Y%m%d.xml" to separate standard input into separate files for each day and channel.  The files will be
       created with names like bbc1.bbc.co.uk-20020330.xml.
