Hi,

Code:
#!/bin/bash

for name in `ls -1 | grep -v $0`
do
        file_name=`echo $name|cut -d. -f1 `
        file_ext=`echo $name |cut -d. -f2-3 |tr -t [:lower:] [:upper:]`
        echo mv $name $file_name.$file_ext
done

just delete the echo and this will do your job.

Tal.

rename(1T)						       Tcl Built-In Commands							rename(1T)

__________________________________________________________________________________________________________________________________________________

NAME
rename - Rename or delete a command SYNOPSIS
rename oldName newName _________________________________________________________________ DESCRIPTION
Rename the command that used to be called oldName so that it is now called newName. If newName is an empty string then oldName is deleted. oldName and newName may include namespace qualifiers (names of containing namespaces). If a command is renamed into a different namespace, future invocations of it will execute in the new namespace. The rename command returns an empty string as result. EXAMPLE
The rename command can be used to wrap the standard Tcl commands with your own monitoring machinery. For example, you might wish to count how often the source command is called: rename ::source ::theRealSource set sourceCount 0 proc ::source args { global sourceCount puts "called source for the [incr sourceCount]'th time" uplevel 1 ::theRealSource $args } SEE ALSO
namespace(1T), proc(1T) KEYWORDS
command, delete, namespace, rename ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWTcl | +--------------------+-----------------+ |Interface Stability | Uncommitted | +--------------------+-----------------+ NOTES
Source for Tcl is available on http://opensolaris.org. Tcl rename(1T)
