nothing in getline

[deanjco]

Hi

Can some one please tell me what I am doing wrong, I have entered the code as below but I don't seem to be getting anything in the line variable it comes back blank


else if ( des == "86" ) {
getline line < &quot;temp86.$$&quot;
if ( FILENAME ~ /mdata/ ) {
if ( allofit == line ) {
m86tot = substr(allofit,43,10)
}
}
else if ( FILENAME ~ /udata/ ) {
if ( allofit == line ) {
u86tot = substr(allofit,43,10)
}
}
}

It appears to be a problem with the shell expanding
the temporary file name by changing the extension
to the next process number.

Simplified, temp.$$ may have originally expanded into
&quot;temp86.2069&quot; when created, but when awk trys to
open this temp file, the shell expands it into some
other extension number ( temp86.2172 ) which, of
course does not exist!

Therefore, nothing can be written into variable &quot;line&quot;
except &quot;&quot;. (NULL)

To get around this, set a shell variable to the file name
expansion when the temp file is created and pass it
into your program using this construct:

Shell variable-

myfile=&quot;temp86.$$&quot; # at creation

In awk file:

getline line < &quot;'$myfile'&quot; # note quoting!

I recommend using nawk/gawk/mawk for doing this
and running in the Bournce shell.

Hope this helps!
