Thanks Dave for informing.

I have a bash script which replaces all tokens in a large with an
identifier (an integer) by doing 'sed'
in a loop. I modified the script a little bit to concatenate all
"s/<orig_token>/<new_token>" using pipes and
ran single 'sed' at the end. But its not working. Thats why I want to
know how many pipes can I open
through a single command. Also, I have tried concatenated the replace
commands using ";". Even
that is not working.
