It doesn't for me in the instance at gcc210.fsffrance.org.

But it did occur to me that the '[ *]' argument might have been the
problem.  Here are my experiments.

bash-3.2$ type tr
tr is /usr/bin/tr
bash-3.2$ echo abc | tr 'ab' '[ *]'
  c
bash-3.2$ echo abc | tr '[:cntrl:]' '[ *]'
Bad string
bash-3.2$ what /usr/bin/tr
bash: what: command not found
bash-3.2$ ident /usr/bin/tr
bash: ident: command not found
bash-3.2$ tr -v
tr: illegal option -- v
Usage: tr [ -cds ] [ String1 [ String2 ] ]

I love these environments where you can't get a command to identify
its own provenance.  Must be "unpublished proprietary source code of
AT&T".  :-|
