Very Computer

I have a large number of Pict files that I wish to convert to ppm under Linux
and am using picttoppm on a single file basis but would like to be able to
issue one command to convert the files all in one go

ie. a command of the form

picttoppm *.pict > *.ppm

but this is not a valid command line is not expanded to the form

picttoppm file1.pict > file1.ppm
picttoppm file2.pict > file2.ppm
etc.

can this job be acomplised with a shell script or a C program or by any
other technique under Linux?

I eventually want to convert the files to Jpeg but have not found a program
that can go straight from pict to Jpeg.

You would be better off asking things like this in a general unix
forum.  To answer your question, yes you can do this by making a
mini-script at the prompt:

If you are using bash, or sh (ksh?):

        $ for i in *.pict
        > do
        > pictoppm $i > `echo $i|sed -e 's/pict/ppm/'`
        > done

If your using tcsh or csh:

        > foreach i (*.pict)
        foreach? picttoppm $i > `echo $i|sed -e 's/pict/ppm/'`
        foreach? end

There is probably an easier way to do the pict->ppm extension
conversion, but this works. :)

Hmm, take a look at ImageMagick (it is on sunsite.unc.edu).

Something along the lines of

ls *.pict | cut -f 1 -d "." | xargs -n1 bob.sh

where bob.sh is:
picttoppm $1.pict > $1.jpg

(This is totally off the top of my head, and most likely needs a little
tweaking/refining)

I could have sworn that I saw somewhere that Image Alchemy was ported
to UNIX... if it is, it should do it.  (I know the DOS version
can convert most anything to most anything else...)
