Well, you could write a ksh script like: { cat <<END_OF_PERL_PROGRAM ... ... perl code goes here ... ... (for a filter using <STDIN> and <STDOUT> ) ... __END__ END_OF_PERL_PROGRAM shell | commands | and | stuff | to produce | input to perl program } | perl -x \ | other | commands | to process | output from perl program Now perhaps I should do it all in perl, but then again, maybe not. It's nice to have the option of having a perl filter in a self-contained ksh script without the dreaded -e stuff. Larry, was this prompted by my question to you in Mountain View the other day?
