Hi Tduell,
I use the shell daily, but only for interactive usage.
I stopped scripting with the shell some years ago. I don't like the shell for
scripting
since:
- The shell does not know the concept of exceptions or stacktraces.
It knows about exit statuses (see next)
- The shell goes to the next line if something is wrong. I want the programm
to stop, not to proceed.
Use the -e flag.
-e Exit immediately if a pipeline (which may consist of a single simple
command), a list, or a com‐
pound command (see SHELL GRAMMAR above), exits with a
non-zero status.
- The shell has major problems handling filenames which contain special
characters.
Use quotes.
does this answer your question? Feel free to ask more details :-)
