Regds,

Yeah,.. I guess when we are first learning something people give us stupid questions to figure out. LOL. Believe me,.. I have way better things I'd rather spend my Saturday night doing but I have to get this finished. Also,.. just remember,.. this is probably really easy for you because you are probably an expert with this but I am just a n00b so there's a lot that doesn't make sense to me yet. But I'm getting better and better at it everday. Smilie

Well, anyway,.. I think I have it all figured out for the most part. Now I just have to make it so that if the number of arguments exceed the number specified in MAXFILES, then it will ask me to confirm the deletion. That shouldn't be too hard. Anyway,.. thanks all for the great help. Smilie

Here's my revised version which works the way I need it to for the most part.

Code:

#!/bin/bash
# Program: myrm

if [ -z "$MAXFILES" -a "$#" -ge 1 ]
then
        for MAXFILES in $1 $2 $3 $4 $5 $6 $7 $8 $9 ${10}
        do
                echo "deleted$MAXFILES"
                shift
        done
        exit 1
fi

if [ -n "$MAXFILES" -a "$#" -ge 1 ]
then
        MAXFILES="$*"
        rm -rf $MAXFILES
fi

Then I just do something like this:

Code:

$ MAXFILES=56 ./myrm f1 f2 f3 f4
# then it deletes the 4 files because they are less than the amount specified in MAXFILES.
or
$ MAXFILES= ./myrm f1 f2 f3 f4

blah blah blah

Also,.. I have just an echo command in the top section just to make things easier. I'll go back and put the correct commands in there later. I just mainly needed to figure out HOW to do it and I think I got it now.

combine

COMBINE(1)																COMBINE(1)

NAME

       combine - combine sets of lines from two files using boolean operations

SYNOPSIS

       combine file1 and file2

       combine file1 not file2

       combine file1 or file2

       combine file1 xor file2

       _ file1 and file2 _

       _ file1 not file2 _

       _ file1 or file2 _

       _ file1 xor file2 _

DESCRIPTION

       combine combines the lines in two files. Depending on the boolean operation specified, the contents will be combined in different ways:

       and Outputs lines that are in file1 if they are also present in file2.

       not Outputs lines that are in file1 but not in file2.

       or  Outputs lines that are in file1 or file2.

       xor Outputs lines that are in either file1 or file2, but not in both files.

       "-" can be specified for either file to read stdin for that file.

       The input files need not be sorted, and the lines are output in the order they occur in file1 (followed by the order they occur in file2
       for the two "or" operations). Bear in mind that this means that the operations are not commutative; "a and b" will not necessarily be the
       same as "b and a". To obtain commutative behavior sort and uniq the result.

       Note that this program can be installed as "_" to allow for the syntactic sugar shown in the latter half of the synopsis (similar to the
       test/[ command). It is not currently installed as "_" by default, but you can alias it to that if you like.
