Nope, same version:
lgoldste@leeann 485% awk --version
GNU Awk 3.0.4
Copyright (C) 1989, 1991-1999 Free Software Foundation.
The line
pci1: <ATI Mach64-GB graphics accelerator> at 0.0 irq 9
will be processed by the clause
/^pci[0-9]+/ {irqinfo = gensub(/(^[a-z0-9]+[: ]).*(<[[:print:]]+>).*([0-9]+\.[0-9]+) (irq [0-9]+$)/,"\\1 \\4 \\1.\\3 \\2", 1)
gsub(/:/, "", irqinfo)
sub(/ [0-9] /, " &", irqinfo)
print irqinfo
next
}
So the problem, whatever it is, is somewhere within the regex used in the
gensub call. All on one line, that regex looks like this (I've marked the
3 blanks in the pattern):
/(^[a-z0-9]+[: ]).*(<[[:print:]]+>).*([0-9]+\.[0-9]+) (irq [0-9]+$)/
^ ^ ^
This should pick out, as individual tokens, "pci1:",
"<ATI Mach64-GB graphics accelerator>", "0.0", and "irq 9". But the way
this is written, if any of those blanks were really a tab, the pattern
wouldn't match, and you'd get the output you're seeing. Try replacing
the 2nd blank with [[:blank:]], which will also match a tab, and let me
know if that works.
