Thanks for the report. However, this is not a bug in tr, but in your usage of the shell. Unquoted, the expression (without "") "[:lower:]" is the glob that expands to any of the existing files: ":", "l", "o", "w", "e", "r"; and if none of those files exists, then the glob is passed verbatim to tr. Your results differed depending on whether the directory you were in had files by those names. But if you had used shell quoting, as in "'[:lower:]'", then there would be no chance for the shell to do globbing. That is, you meant to do: echo ABCD Directory | tr '[:lower:]' '[:upper:]' and were only getting lucky that there weren't any one-character file names in your first directory. -- Eric Blake [email protected] +1-801-349-2682 Libvirt virtualization library http://libvirt.org
