hey methyl,
trying to look for regular files, with one or more inodes, modified within the last 30 days.
variable a would display time last accessed, b would display time last modified and c would display full path of the file.
could i have done without the-inum +1? thanks.
A regular file will have one inode within the filesystem. That inode has a unique number within the filesystem. That inode number is the number referred to in the "-inum" parameter to "find". It is the same number you get with the "-i" switch to "ls". When there is a hard link to a file within that filesystem it is possible to have more than one name for the same inode number.
The "-inum +1" switch is pointless in this context.

Without knowing what Operating System and Shell you have it is hard to propose a solution. I see that "agama" has posted a neat solution with the "stat" command which is available on some Operating Systems.

SYNOPSIS

       num] num] inode-list] num] file] prefix] special ...

DESCRIPTION

       The  command  reads  the  i-list and directories of each special file special, assuming it to be an HFS file system, saving i-node data for
       files that match the selection criteria.  Output consists of the path name for each saved i-node, plus any other file information requested
       using  the  print options below.  Output fields are positional.	The output is produced in i-node order; fields are separated by tabs.  The
       default line produced by contains the path name and i-number fields.  With all options specified, the output fields include path  name,	i-
       number, size, and user ID.

       The  num  parameter  in the options descriptions is a decimal number, where means more than num, means less than num, and num means exactly
       num.  A day is defined as a 24-hour period.

       lists only a single path name out of many possible ones for an i-node with more than one link, unless you specify the option.  With applies
       no  selection  criteria	to  the names listed.  All possible names for every linked file on the file system are included in the output.	On
       very large file systems, memory may run out before completes execution.

   Options and Arguments
       recognizes the following options and arguments:

	      Select a file if the i-node has been accessed in
			     num days.

	      Select a file if the i-node has been changed in
			     num days.

	      Specify the HFS file system type.

	      Generate names for any i-node specified in the
			     inode-list.

	      Do not display the i-node number after each path name.

	      Generate a list of all path names for files with more than one link.

	      Select a file associated with an i-node if it has been modified in
			     num days.

	      Select a file associated with an i-node
			     if it has been modified more recently than the specified file.

	      Add the specified
			     prefix to each path name.	The default prefix is (dot).

	      Write the file size, in bytes, after each path name.

	      Write the owner's login name after each path name.

	      Echo the completed command line, but performs no other action.
			     The command line is generated by incorporating the user-specified options and other  information  derived	from  This
			     option allows the user to verify the command line.

EXAMPLES

       List the path names and i-numbers of all files in the file system

       Same as above, but suppress the printing of i-numbers:

       List  files  on	the  same  file  system  that  have been modified recently, displaying the path name, i-number, and owner's user name (the
       option).  List only files that have been modified within the last two days (the option):

       List all files on the same file system, including the path name and i-number of each file, that was last accessed more than 30 days ago

       Find all path names associated with i-nodes and (the option):

       Execute the command on an HFS file system

FILES

       Static information about the file systems.
