I need to write a program using sed and awk and am new to this unix stuff. So if anyone can give me any pointers that would be great. Here is what I need to do. # 7 I can do.

1. Accept two and only two command line arguments
2. These will be the names of two directories
3. Make sure sending directory exists and is a directory
4. make sure receiving directory exists and if not create it.
5. copy files that only have a suffix of .log and are not empty
6. When copying files change suffix of filenames from .log to .abc
7. Display count of number of files copied.
8. Log files will contain 2 columns of data, when you copy switch the order of the columns in the files you create in the receiving directory.

Thanks.

LEARN ABOUT SUNOS

install

install(1B)					     SunOS/BSD Compatibility Package Commands					       install(1B)

NAME

       install - install files

SYNOPSIS

       /usr/ucb/install [-cs] [-g group] [-m mode] [-o owner] filename1 filename2

       /usr/ucb/install [-cs] [-g group] [-m mode] [-o owner] filename... directory

       /usr/ucb/install -d [-g group] [-m mode] [-o owner] directory

DESCRIPTION

       install is used within makefiles to copy new versions of files into a destination directory and to create the destination directory itself.

       The first two forms are similar to the cp(1) command with the addition that executable files can be stripped during the copy and the owner,
       group, and mode of the installed file(s) can be given.

       The third form can be used to create a destination directory with the required owner, group and permissions.

       Note: install uses no special privileges to copy files from one place to another. The implications of this are:

	 o  You must have permission to read the files to be installed.

	 o  You must have permission to copy into the destination file or directory.

	 o  You must have permission to change the modes on the final copy of the file if you want to use the -m option to change modes.

	 o  You must be superuser if you want to specify the ownership of the installed file with -o. If you are not the super-user, or if  -o	is
	    not in effect, the installed file will be owned by you, regardless of who owns the original.

OPTIONS

       -c	       Copy  files.  In fact install always copies files, but the -c option is retained for backwards compatibility with old shell
		       scripts that might otherwise break.

       -d	       Create a directory. Missing parent directories are created as required as in mkdir -p. If the directory already exists, the
		       owner, group and mode will be set to the values given on the command line.

       -s	       Strip executable files as they are copied.

       -g group        Set the group ownership of the installed file or directory. (staff by default.)

       -m mode	       Set the mode for the installed file or directory. (0755 by default.)

       -o owner        If run as root, set the ownership of the installed file to the user-ID of owner.
