    How do I test for the presents of a character in a string?

    I am trying to complete a script that reads a text file and only includes lines that do not start with a "#" symbol. How would you go about it?

    Thanks in advance

    use grep with the -v option and escape the #. For example, if you are catting "test.txt"

    cat test.txt | grep -v \#
    this will display all lines within test.txt excluding any that contain a "#".
