Using While and If statements

Hi guys,

Two problems I need solving please. I created a script where the user types in 7 numbers as standard input and each one is then stored in an array. Now I need to perform the following calculations on those numbers:

1) Use a while loop to determine the largest number in the range.

2)Use an If statement to calculate the median within the range.

Please provide each suggestion with the simplest command structure possible.

Many thanks for your help!

Jared.

ncheck_hfs

ncheck_hfs(1M)															    ncheck_hfs(1M)

NAME

       ncheck_hfs: ncheck - generate a list of path names from inode numbers for a HFS file system

SYNOPSIS

       inode-numbers] [special ...]

DESCRIPTION

       when  invoked  without  arguments, generates a list of path names corresponding to the inode numbers of all files contained on the HFS file
       systems listed in If special is specified, ncheck reports on the special only.  Path names generated by are relative to the given  special.
       Names of directory files are followed by

   Options
	      Allow printing of the names
			     and which are ordinarily suppressed.

	      Specify the HFS file system type.

	      Report only on files whose inode numbers
			     are specified on the command line, in inode-numbers.  inode-numbers is a comma separated list of inode numbers.

	      Report only on special files
			     and regular files with set-user-ID mode.  The option is intended to discover concealed violations of security policy.

	      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.

	      Report only on files using sector numbers
			     specified on the command line in sector_ranges.  sector_ranges is a comma separated list of sector ranges.  A  sector
			     range is a starting sector number and an ending sector number separated by a dash, or just a sector number.  The sec-
			     tor numbers should be in DEV_BSIZE units.	If no pathname contains the sector number it will be reported as  free	or
			     containing file system structure. Sectors beyond the end of the file system will be reported as illegal.

   Access Control Lists
       Continuation  inodes  (that  is, inodes containing additional access control list information) are quietly skipped since they do not corre-
       spond to any path name.

EXAMPLES

       Execute the command on all special in

       Execute the command on HFS file system

EXTERNAL INFLUENCES

   International Code Set Support
       Single- and multi-byte character code sets are supported.

DIAGNOSTICS

       When the file system structure is improper, denotes the ``parent'' of a parentless file and a path-name beginning with denotes a loop.
