Power Need a command to delete all files apart from last file generated

Hi,

I have a directory named (/output). this directory has files in the below format
Code:
abc.* , 
xyz*, 
djj*, 
iwe*, 
weewe*, 
rier*, 
3948903ddfgf*

these files are generated at random. what i need to do is. delete all the files of all kinds but keep only the last generated file of eachtime.

the final result will have only 1 type of file for each of the files present in the folder. the file that will be present will be the latest file.

NAME
binhex - Hexifies a series of files SYNOPSIS
binhex [ - options ] [ files ] DESCRIPTION
binhex takes the files specified in files and hexifies them in BinHex 4.0 format on standard output subject to the options specified. If files also specifies directories they are followed recursively, and all files found will be hexified. If no files parameter is specified, binhex reads a MacBinary stream from standard input and hexifies the files found; folder information is lost. OPTIONS
In the absence of any options, binhex takes the specified files and silently hexifies them to BinHex 4.0 format, writing the result to standard output. Directories named in files are followed recursively, all files found will be hexified. Files are assumed to be in MacBi- nary format. However, if the filename ends with .info the file is assumed to be the info fork of a MacIntosh file split amongst more than one file. In that case the files with .data and .rsrc extensions are also read (if present). Also, if the info fork is mentioned in the parameter list, the names of data and resource forks can also be mentioned, but those will be ignored (this is to allow wild-card expansion by the shell.) Further, if some form of AppleShare is supported by the installed program, and if the current directory, or one of the directories found during recursive processing, is a directory in the format of the supported version of AppleShare, those files will be handled according to the properties of AppleShare. -r No intelligent file-processing is performed; all files named are assumed to be plain resource files, and are hexified as if they were MacIntosh resource files with creator "RSED" and type "RSRC", unless another creator and/or type are specified. -d No intelligent file-processing is performed; all files named are assumed to be plain data files, and are hexified as if they were MacIntosh data files with creator "MACA" and type "TEXT", unless another creator and/or type are specified. -u As -d, but the codes for CR and LF are interchanged. -U Is a synonym for -u. -c creator Defines the creator name to be used if one of the previous options is specified. -t type Defines the type name to be used if one of the previous options is specified. -R Do not use run-length encoding during the conversion. This option may speed up the encoding a bit, but it is merely a historical artifact. -l List every file and directory processed. -i Do not output files, give information only (implies -l.) -q Ask the user for every file/directory whether it should be visited (implies -l.) -V Gives the patchlevel of the program, and other information. Other options are ignored and the program quits immediately. -H Give short information about the options. Other options are ignored and the program quits immediately. BUGS
