Converting file names to upper case
Hi all,

I am trying to rename all my files in a directory to their upper case counterparts .... I want to do this in a single command and not through shell script ... I started off thinking it wud be simple but got stuck up in middle since tr does not work the way i thought ...

This is what i tried ...

ls | xargs -l1 -t -i mv {} `echo {} | tr '[a-z]' '[A-Z]'`

Here tr does not seem to do any work and just returns the file name as such .. So in effect i am renaming a file to that name itself ...

mv try.cc try.cc
mv: try.cc and try.cc are identical
mv typescript typescript
mv: typescript and typescript are identical

Why is this happening ?? And can anyone suggest me a solution

pseudo

pseudo(1)						      General Commands Manual							 pseudo(1)

NAME

       pseudo - Starts a non-STREAMS pty interface for a STREAMS device

SYNOPSIS

       pseudo [-l] [-shell shell]

OPTIONS

       Starts  a shell process as the login shell. By default, the command starts this process as an interactive shell.  Specifies the shell to be
       started.  By default, the command starts the shell set by the SHELL environment variable.

DESCRIPTION

       The pseudo command provides an appropriate interface for STREAMS tty devices that are installed on  systems  configured	to  use  the  non-
       STREAMS pty driver.

       The  pseudo  command  opens a pair of master and slave pty devices, and starts a shell process. The command's options allow you to override
       the default shell specification and to specify that the process be started as a login shell.

NOTES

       The pseudo command is available only when one or more of the Tru64 UNIX optional subsets with worldwide support software are  installed	on
       your system.

       In  order  for the pseudo command to provide a non-STREAMS pty interface for STREAMS devices, the system must be configured to use the non-
       STREAMS pty driver. If the system is configured to use the STREAMS pty driver, the command provides a STREAMS pty interface.
