In order to purge the temporary context files I did (throught an alias) texutil --purge This worked fine. Since the introduction of the ruby scripts this call now tells me: remark: 'texutil' is now part of 'texexec' warning: use 'texmfstart texutil' instead So I obediently call: texmfstart.rb texutil --purge This silently does nothing. Neither does work "texmfstart texexec --version" the same as did "texexec --version". The former giving the TeXExec version, the latter gave the installed ConTeXt formats. It is not "texmfstart texexec --purge" because I tried that too. On the other hand, replacing "texexec --silent --pdf --autopdf file.tex" by the same preceded with "texmfstart" does work as expected.
