    This is bad practice. A much better way would be to use $$, which is the process ID. In the loop above I would create a filename of “/tmp/$(basename $0).$$.txt”

    or both… /tmp/$(basename $0).$RANDOM.$$.txt

    say hello to the safe side

    :D

    Not testing if the file to be created already exists is a rather bad idea
