Shell Programming and Scripting

Hello All,

I have got a dev server and a production server will call it as D server and P server.

I have a dir structure in my D server and i need to create the same dir structure in P server also using a shell script.

If i do a find . in my D server, i am getting an o/p like :-

Code:

.
./vio
./vio/common
./vio/common/esr_begin
./vio/common/esr_end

.... and so on .. D server contains directories like :-

Code:

drwxrwxr-x  23 smbnull    sys           4096 Feb 23 03:13 aix
drwxrwxr-x   3 smbnull    sys           4096 Feb 22 04:52 hpux
drwxrwxr-x   3 smbnull    sys           4096 Feb 22 05:02 linux
drwxrwxr-x   3 smbnull    sys           4096 Feb 23 09:41 vio

Inside this lot of other dir/files ..

So I need to create files and directories (with same content)as we can see in D server to P server. I am using a mail parsing mechanism to create files and directories in P server. It is like :-

Code:

cat default.cfg | mailx -s "ESR MANIFEST /scripts/sys/hostupd/ESR10.2/aix/default.cfg" mailid

My worry is how will i create the exact file/dir structure ..?

Thanks in advance

The tar command is your friend. No need to elaborate a bunch of scripts for this task.

on D server got to place where you did find command

Code:

$ tar zcvf  vio.tgz vio/

if you have scp/rcp/ftp allowed it is much easier
copy all the files to P server


if you have to mail ... remember you cannot mail like you do for text file.
you need to encode the file before you email.

Code:

uuencode vio.tgz vio.tgz  | mail chakrapani@newsasnow.com -s "Dev dump"

now on production server

Code:

$ tar zxvf  vio.tgz

Please note command carefully
tar - create tar archive
z - Gzip it
c - CREATE (which is done on DEV D server)
v - verify show what it has done ...
f -- file to be used
x - extract (which is done on PROD server)


if you need a script decide how files are compressed and rcvd on production. also verify userid permission etc before you copy etc ...

there are easier ways like rsync to copy files and cvs/version control etc to make it structured ...

Let me know if you need more help ...

Code:

mkdir -p

your full path of directories

No, I have to do email parsing since i dont have access to P server. I can only use email parsing...

I have got the idea but dont know how to implement ..

Algorithm will be like :-

1) find . will give all the files and dir in the desired location
2) store the o/p to an array
3) if it is a dir --> use parsing method to create dir
4) if it is a file --> use parsing method to create file

and so on ..

This is the logic i want ..
Please help me out to complete this since i am not familiar with array and all ....

Thanks

Only copy a directory structure

on D server:

Code:

find . -type d > folder.list

on P server:

Code:

cd /DIR
cat folder.list |xargs mkdir -p

It is not possible since i dont have access to create folders or dir in P server...

Please tell me how to read entries into an array .
Example :-

/opt/src
/etc/sys
...
...
I need to store "/opt/src" as first element in the array and "/etc/sys" as second and so on ..
Then I need to check if the first element in the array is a dir .. then i will use email parsing to create the same in p server ..

Please suggest ..

Thanks
