I have the following command in my .bashrc:

```
alias mfigpdf='for FIG in *.fig; do fig2dev -L pdftex "$FIG" "${FIG%.*}.pdftex"; done;
                 for FIG in *.fig; do fig2dev -L pstex_t -p "${FIG%.*}.pdftex" "$FIG" "${FIG%.*}.pdftex_t"; done'

```

And I want to execute the 'mfigpdf' command in my Rakefile:

```
desc "convert all images to pdftex (or png)"
task :pdf do
  sh "mfigpdf"
  system "mfigpdf"
end

```

But none of theses tasks is working. I could just copy the command in the rakefile of insert it in a shellscript file, but than I have duplicated code.

Thanks for your help!
