Hello,

i wanted to make a newLisp app to grab data from an extsting proces. Example:

>> ls /usr/share | grep init
initramfs-tools
initrd-tools
initscripts


As you can see, in the first line I used a "pipe" to connect "ls" command with "grep".
How can I get data input from shell pipe using newLisp (like grep in the previous case)? How can I send data output to shell pipe using newLisp (like ls in the previous case)?


thank you.

Look for the sections about pipes and filters here:

we.g. with this program named 'upper'
you could do:
and would get an uppercase directory listing
