But that won't work for files with commas in the name! (Rare, but it
can happen...) I'd prefer something like
This still works fine for filenames with commas since it uses $* which
joins the positional parameters which have already been split (before
the subprocess was even invoked), before IFS is changed to ",".
But if a filename has a comma in its name then it is impossible to
express it as a list of comma-separated filenames without some form of
quoting. And I doubt that the email program has backslash-escape
parsing logic for this very rare case (but I haven't checked.)
Regardless, this:
email user@example -s test -a "$(ls -1 *.pdf | tr '\n' ',' )" < sample.txt
...does not solve the problem either. You get the same output as above,
except with an erronious trailing ",".
