Full Discussion: Listing the files in a directory
Homework and Emergencies Homework & Coursework Questions Listing the files in a directory Post 302737051 by Corona688 on Wednesday 28th of November 2012 10:24:54 AM

Thank you for filling out the template.

A few problems:

1) Variables can't have spaces in their names. No of dir = $# is wrong.

2) You shouldn't put spaces on either side of the equal sign. something = asdf is wrong. Do something=asdf

3) You got your if-statement nearly right, but not quite. Don't capitalize anything. Your ; is also in the wrong place.

If it helps, imagine it like this:

Code:
if [ something ]
then
...
fi

To combine any of that onto one line, you'd put ; where there's newlines, so you'd get if [ something ] ; then

4) You can't put a variable in a variable like this: ${$count} it just doesn't expand there. There's a better way, anyway.

The shift command will get rid of the first parameter. If your parameters were a b c d before, after you run shift they will be b c d. So you can loop until $# is zero, running shift at the bottom of your loop, using $1 every time instead of using $1, $2, $3...

shift

shift(1)                                                           User Commands                                                          shift(1)

NAME

       shift - shell built-in function to traverse either a shell's argument list or a list of field-separated words

SYNOPSIS

   sh
       shift [n]

   csh
       shift [variable]

   ksh
       * shift [n]

DESCRIPTION

   sh
       The positional parameters from $n+1 ... are renamed $1 ... . If n is not given, it is assumed to be 1.

   csh
       The  components of argv, or variable, if supplied, are shifted to the left, discarding the first component. It is an error for the variable
       not to be set or to have a null value.

   ksh
       The positional parameters from $n+1 $n+1 ... are renamed $1 ..., default n is 1. The parameter n can  be  any  arithmetic  expression  that
       evaluates to a non-negative number less than or equal to $#.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
           able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
           performed.
