KORN: Looping through output of command
 
In bash, I normally use this to read each line of output:

while read line
do
echo $line
done < <(cat /myfile.txt | cut -f1 -d" ")

But this doesn't fly in KSH. I can't find the same thing on any tutorials, doesn't anyone know how to do this in Korn?

Code:
#!/bin/ksh
cat /myfile.txt | cut -f1 -d" " | \
while read line
do
echo $line
done

or with a closer syntax:
Code:
#!/bin/ksh
while read line
do
echo $line
done <<%
$(cat /etc/hosts | cut -f1 -d" ")
%

This method works perfectly. The other one that was posted kept giving me "% unclosed" errors.

Huh ?

Please double check, it works for me with both the real ksh and pdksh.

You probably missed to copy the last line: "%"
