Also gets around nasty "argument list too long" messages and doesn't need you to remember arcane syntax. $A is quotable if you have spaces in the filename.

I can't find what I'm looking for in the bash(1) manpage, hoping there's an
easy answer...

I want to use a construct like
       for i in ~/path/*; do something $i && rm $i; done

which works great as long as there are files in ~/path/.  However, when the
directory is empty, I get:
       rm: cannot remove `/home/athompso/path/*': No such file or directory

which isn't quite what I want.  The quick fix in this case is to use
       for i in ~/path/*; do [ -f $i ] && something $i && rm $i; done

but once again, that strikes me as inelegant and I can't remember OR find
the better way to do it.

Anyone?

Thanks,
