Need help with writing a c shell script?
Hi All,
I want to write a C/perl shell script but I am not sure exactly to go about writing it.This is what how I can expalin you what the script should exactly do.You need not tell me the code but just point me in the direction and tell me the commands that I can use

I have a directory structure where actually the code resides.different file types are in different folders.The basic idea is as follows
When I run the script it should tar the files in the folder them.
Then it should ftp the file to an ip address that I give in a command then it should untar the file in a particular directory structure that is similar to the one that I have tared the file.this I should ideally be able to do in a single shell script.
Please let me know how I can go about writing the script.

Thanks for all your inputs.

A "shell script" is normally written in the language of the shell. Otherwise you'll simply be writing a "Perl Script"---etc.

As for "C script"--I don't know what that would be---unless it were a shell script running in the "C Shell"

to write the actual script, start by trying all the individual commands. The first thing that jumps out at me is I am not sure that "tar" is available in the ftp protocol. (Uncle Google will know.....)

Next, if you start an ftp client during your script, then you need a way of passing ftp commands to ftp---I assume it's possible, but I've never seen the procedure.

Thanks Pixellany.That should get me started

I guess I will write the script in a perl.I want to pass my PWD output as a tar argument.Can you tell me how can I do that in perl.
I quick search in uncle google gave me this link.

I want to pass my PWD output as a tar argument.
Put the output of PWD into a variable, then expand the variable as part of the tar statement---use quoting rules as required.


Can you tell me how can I do that in perl.

Why not just use BASH?----I don't know PERL, so I'm not really qualified to be asking you this......;)

probably a single rsync command will do this job, you only need to find out the flags you want to use.

Happy with solution ... mark as SOLVED

For Perl see &, but ftp doesn't support non-ftp cmds like tar.
If you want to do it all in one 'script' then use eg Perl and scp it instead.
