  • shell programming

    hey everyone howz it oging? am a complete noooooooooob to shell programming. i saw a few codes and applications and i already feel like running away lol i like my programming but with like java, vb, and even C++ but this hear looks all too new for me. so i decided i'd take it step by step like in java, the first prg they teach u is how to print HELLO WORLD so i do the same in bash. ok so here's my prb. say am in a directory and i want to find out how man files are jpegs and exe. like the result would b cout<<u have 10 jpegs and 5 exe
    how do i get the name of a file and how do i check if it's an exe or not? a jpeg or not?
    can someone just write a loop for this? a few lines checking if files are jpeg or not. no it's not an assignment although if u find it somewhere plz tell me lol cuz i'd rather read about it then ask
    anything u can offer be it a complete answer or link or anything would b most appreciated. thnx and good day ^_^

    ps. i think i put this in the wrong place but i wasnt so sure. sorry. didnt know if it were here or in general linux and id idnt want to double post on my first day lol

    Maybe this... not sure what you are wanting:
    ls | xargs file

        Better yet just use file without ls. Go to any directory you are interested in and type:
        file *
        Add a | grep -v directory to the end to only get a list of files (instead of files and directories). I'm online, but the easiest way to communicate is right here through these forums since I never know when I'll be on. Responding to posts is easy and can happen at any time (especially since I'm at work most of the day).
