Very Computer

if i have function:

   func_a ()
   {
     printf "  I'm in '%s'\n" how_do_I_get_function_name;
     ...
   }

How do I get the function name.

I'll be writing a lot of these, lots of cutting and pasting.
It will be VERY easy to forget to change the name of the function
nested within the function.
So how do I get the name?

    In bash, there is the variable, FUNCNAME:

func()
{
  printf "FUNCNAME = %s" $FUNCNAME

    I have never needed it; why do you?

Just one way.  For each task I will have a function by the same name  It will
also be part of the output directory.

The more I can cut/paste without having to edit, the better off I am.

Or: The more I can cut/paste without having to edit, the WORSE off I am.

I know that sounds facetious, but all I'm trying to point out is that if
you're doing a lot of cutting and pasting without editting, then you're
duplicating a lot of code which leads to maintenance problems in future
when you want to make a small tweak (or major rework!) and find you have
to make the same change in multiuple locations.

So, just think about it....

Also consider if there'd be any value in these functions being stored in
separate files, e.g. so you can call them from the command line or from
different scripts. If so, you can use `basename $0` (which isn't
bash-specific) or it's ilk instead of $FUNCNAME to get the "function" name.

You can use a function to define the function:

myfunction() {
  eval "
    $1() {
      funcname='$1'
      $2
    }"

Quote:}

Then:

myfunction abc '
  outdir=$OUTDIR/$funcname
  ...
'

But that won't make things easy if you need to use single quotes
in the code of your functions. Alternatively, you could do:

myfunction() {
  eval "
    $1() {
      funcname='$1'
      `cat`
    }"

Quote:}

myfunction abc << \EOF
  outdir=$OUTDIR/$funcname
  sed 's/#.*//' < "$infile" > "$outdir/$outfile"
EOF
