Thanks for your reply;
I cannot decide if to make a copy of the file or not, this particular file contains particular data of the current day, so it has to be archived in another directory before re-creating it.

a) I want (in this case) this file generated in $DEFAULT_PATH/$2, but this script is used by other jobs: in other cases (other jobs) the script takes the file (another file) and archives it (archiving: i mean appending the current time and date) in the same folder where the file is located (so sometimes it acts only as a "rename".

b) I know that file has just been moved to another location, but also this script (touch) is used in other situations: in other situations you must now if a particular file exists or not, because the presence/absence of the file influences the behavior to assume (so you must have scripts that can be usable in different situations)

c) I want this file moved in $DEFAULT_PATH/$2 (but as i previously said, in other situations the archive can occur in the same folder,I mean the origin folder, because the same script is used)

d) the touch script tries to re-create the file with its original name (I mean without timestamp) in the origin folder, for example:

origin folder: /usr/origin_folder/
file to archive : fileA (so you have /usr/origin_folder/fileA)
archive destination /usr/destination_folder/

-> at the end you must have /usr/destination_folder/fileA<date_time> (ex: fileA20110329161000 (2011 03 29 16.10.00)

e) after you have to re-create /usr/origin_folder/fileA, because this file should be processed by other programs, and archived at the end of the day. The day after, the programs that insert data into the file must find this file in the specific folder (so after archiving it you have to re-create it), and so on..

The needs of code are, as you said:

a) rename $1 in $1<date> (or $1.date it's the same) in the origin folder.
b) archive (mv) $1<date> in $DEFAULT_PATH/$2 (in this case; in other cases the script must archive the file in the same directory where the file is located, so i put a confrontantion of origin folder and destination folder, and if they are the same, only a rename (step a) occurs.
c) In this case i have to re-create the file that has just been archived ( I cannot put the touch command inside the movedate script because the script is used in other situations where the file to archive is not created but is uploaded or send by other systems). But for this, i think i can use a simple touch command.

So the needs are a) and b)

Thank you!
