Hello,
I would like to find some directories and rename then.
I use
find . -type d -name 'tau_*'
to find directories starting with "tau_". I would like to change
the underscore to a hyphen in the directory names use -exec, but can
not figure out the syntax.

And it seems to complicate the problem that there are tau_*
directories under some other tau_* directories...

You can see previously the output with the "echo", so:
find . -type d -name 'tau_*'|while read D;do echo mv -i $D ${D/
_/-};done

If you can, consider using the "rename" program (available on most systems).
Otherwise, you can try this (with bash):
find . -depth -type d -name 'tau_*' -exec
sh -c 'b=$(basename "$1");d=$(dirname "$1");
nn=${b//_/-}; mv -- "$d/$b" "$d/$nn"' sh '{}' \;
But I suggest you run this before:
find . -depth -type d -name 'tau_*' -exec
sh -c 'b=$(basename "$1");d=$(dirname "$1");
nn=${b//_/-}; echo "would perform mv -- $d/$b $d/$nn"' sh '{}' \;
To see what the program would do. The run the real one above.

All the commands are tested with bash and GNU tools, so they may use
nonstandard features. I try to mention when something is nonstandard (if
I'm aware of that), but I may miss something. Corrections are welcome.
