    Unanswered: Newbie Bourne shell function question

    I was just given a temporary UNIX assignment (Bourne shell) and I am unfamiliar with a lot of basics. I added a number of functions to the .profile but our entire group uses this account and I was asked to remove them. I tried simply copying the text from .profile into another file and executing that file but the functions declared in the file were not found when I typed them on the command line. Nobody here knows about or uses functions and they cannot tell me how to make functions available. I Googled tutorials for several hours without finding out how to do this. I don't know if each function has to be in a different file, the filename needs a particular naming convention, or needs to be explicitly added to my path, or if I need to make the file a library. A portion of the code that appears in the file (mbinit) appears below. If anyone can tell me how to make a bunch of functions available to me or point me to an online tutorial that explains it, I would appreciate it.

    Question answered

    I ran across the concept of sourcing the file and that solved my problem. Instead of executing the file, I used . ./filename.

    You can also use the "source <file>" bash-builtin. It does the same as ". <file>", but maybe clearer and easier to understand in case this is code that shall be maintained by others in the future.
