Read from Standard in

Hallo, I'm new in this form and I',m starting using awk for scripting.

I've a problem with a script within Suse Linux/AIX.

Using the following script to give out Names and according values. It should be possible to change the values and write it back to the outputfile. But on a AIX-System the script doesn't work:

#! /bin/awk -f
BEGIN{
anfang=13
FS = "="
out = "hardwareinfo.mif"
print "" > out
}

{name=$0}
{if (NR>anfang&&$0 ~ /Name/) {
print $2
}
}
{if (NR>anfang&&$0 ~ /Value/) {
print $2"\n\nBitte neuen Wert eingeben"
getline x < &quot;-&quot;
name = &quot; Value = \&quot;&quot; x&quot;\&quot;&quot;
}
}
{print name >> out
}

Any Idea ?

Thanks and reguards

How do you run this script?
If its

awk -f script hardwareinfo.mif

then you're going to be modifying the file as you read it.

But it works on Suse Linux?

It's almost certain that you're using GNU AWK on the Linux box, which has many extensions is recognising this as meaning read from stdin.

Not sure if this would still work on your AIX machine, but you could try
getline x < &quot;/dev/stdin&quot;
