I need to create a script that uses an 'if' command that checks whether there is exactly one argument. If there is more than one argument, I need it to echo “Usage: give exactly 1 argument, the string to be looked for” and then exit immediately.

Welcome to Stackoverflow.

This should do the trick:

if [ "$#" -gt 1 ]; then
    echo "Usage: give exactly 1 argument, the string to be looked for"
    exit 0
else
   echo the expected processing happens in this section of this code
