Another, probably more stupid question - How does one read a text file line by line in an rc script.
In bash this works:
#!/bin/bash
while read line
do
echo $line
done < $1
I’ve tried:
#!/bin/rc
while (line=`{read $1})
{
echo $line
}
Which produces the first line of the file in an infinite loop. I’ve tried the -m argument with no output.
It’s probably simple, but just can’t seem to find the equivalent.
Regards,
Mack
