newbie; appending multiple files

[Steve]

Hello,

I have files 1.txt, 2.txt, 3.txt.......n.txt. Each file contains a
single line of text. I need each line of text from all these source
files to be appended into a single destination file called bulk.txt.

I have found some marginally helpful stuff in the manpages and faqs
but not quite what I need. Any pointers are appreciated.

Thanks,
Steve

And your Perl question is ...?

cat ?.txt > bulk.txt

ought to do it.

The OP said append so that should be:

cat ?.txt >> bulk.txt

Dunno about the Perl question, but the Perl answer is

perl -e'print while <>' ?.txt

perl -e'print while <>' ?.txt

And 'print while <>' is the -p option ...

$ echo xxx > bulk.txt
$ echo aaa > 1.txt
$ echo bbb > 2.txt
$ echo ccc > 3.txt
$ perl -pe "" ?.txt >> bulk.txt
$ cat bulk.txt
xxx
aaa
bbb
ccc

I suppose this *might* be useful on a platform that has perl but lacks
cat or a decent shell?

Sure, but even in later versions of DOS (at least v3+, IIRC) you
could use

C:\> for %f in (?.txt) do type %f >> bulk.txt

and under win2k at least, 'type ?.txt > bulk.txt' seems to work as
you might expect. The DOS shell is not completely brain-dead, just
mentally retarded.

Not that this has anything remotely to do with Perl...
