Renaming files in a bash script
I'm doing a short batch script to compile po files producing output binary mo files.

The compilation command is:
msgfmt -o file.mo file.po

so in order to compile I am appending .mo to the varible in a loop.

It goes something like this:
for i in `find . -name "*.po"`
do
echo "Compiling $i"
msgfmt -o $i.mo $i
done

The result are file.po and file.po.mo files, but what is requeried is
file.po and file.mo.
SO I tied renaming after the compilation command with:
mv $i `expr $i : '\(.*\).po'` #rename 'file.po.mo' to 'file'
mv $i $.mo

but $i does not equal 'file', so the last line fails. I tried a few things like using awk and assigning another variable to 'file' and renaiming that, but yet to no avail.

Any ideas?
Thanks

maria-cso

MARIA-CSO(1)						      General Commands Manual						      MARIA-CSO(1)

NAME

       maria-cso - shared library generator for maria

SYNOPSIS

       maria-cso directory library.so file.c...
       maria-cso directory library.so file.c

DESCRIPTION

       This manual page documents briefly the maria-cso command.

       maria-cso  is  a  shell	script	invoked  by maria in order to compile generated C code into dynamically loadable shared object files.  The
       script invokes the C compiler and the linker, and it calculates checksums in order to avoid compiling unmodified modules.
       The directory argument specifies the location of the source files.  When the script is invoked with one file.c argument, it translates  the
       file to the shared object library.so.
       When maria-cso is invoked with multiple file.c arguments, it computes a checksum of a file named multiset.h and of each argument.  When the
       header file multiset.h has been changed since the previous invocation of maria-cso, everything will be recompiled.   Otherwise  only  those
       file.c modules that have been modified will be recompiled.  The checksum files are multiset.sum and c.sum.

SEE ALSO

       maria(1), sh(1).

ENVIRONMENT VARIABLES

       CC     Name of the C compiler

       CFLAGS Command-line switches to be passed to the C compiler

       DEFINES
	      Preprocessor macro definitions to be passed to the C compiler

FILES

       /usr/share/maria/runtime/*.h
	      Header files for the run-time library

       This  manual  page  was	written  by Marko Makela <msmakela@tcs.hut.fi>.  The maria-cso script and the compilation option were designed and
       implemented by Marko Makela.  Please see the copyright file in /usr/share/doc/maria for details.
