Hi. I would like to know what the difference between shell programming, scripting and unix programmming is? I am doing c shell scripts and could somebody recommend me a book that I could purchase online??? Thanks.
As a hardware person I group shell programming and scripts like perl, tcl/tk etc. in the same class. These programs are interpreted i.e. some other binary program reads the ASCII file, parses it line by line and then executes each line.
c, c++, fortran and others use compiliers to convert the source code into a binary executable.
I do not know what you mean by unix programming except it involves both interpreters and compilers.
Just to nitpick, perl is 'compiled' in memory and then that version is run, which is why it's so quick.
See the '-c' option if you want it to do the compile without running.
Technically it's more of a compiled env that is run, as you wouldn't get a binary executable on disk, although there are tools to do that.
Unix programming can either mean programming on Unix (in the lang of your choice) or writing Unix OS / driver code. It' a context thing.
