Shell Programming and Scripting

I am posting a script below which essentially excutes the following functions in the described order.

1) From a source directory pools together three files generated by system logs for each user session, tar's these files and archives them as a log set in a destination directory and these removes the three files which were zipped and archived from the source directory.

2) The zipped and archived logset will be tagged as sudosh.actual date the files were created (mm/dd/yyyy) format .hostname .tar

3) The script is designed to clear a backlog of files created in source directory of each box.

4) If there were no user log files on a particular day then a zero tar logset is created with a tag .nologs.sudosh. date (mm/dd/yyyy) .hostname.tar and archived in destination directory.

Note : Th script works fine when there are no log files and just files generated by one user session which gives only one "v_fileid" parameter to the script.

However if there are multiple user sessions generating multiple log files on a a particular day it creates multiple parameters for teh V-fileid variable which the script is unable to process and denotes an error that files could not be opened for that particular day .

can someone assist me by showing how I can update the "v_fileid" variable to accept a list or multiple parameters in addition to zero and one parameter for a particular day and process the rest of the script to accomplish the tasks noted above.

I believe there may be a small syntax modification that can be done to the existing script to make it accept and work in the scenario where there are more several files created in the source directory because of multiple user sessions generating a list of parameters for the v_fileid variable in the script noted below.

Request urgent assistance in making this script work when zero, one or multiple parameters exist for a given day. Thank you.
