You should have noticed that earlier when our one-liners did `cat
test.txt`. Anyway, assuming FILE is a constant filename pattern. Here
is a ruby one-liner. (ruby -ne 'puts
$_.gsub(/FILE./){"#{File.readlink($_.strip)}"}' test.txt > tmp ; mv
tmp test.txt). Yes the temporary file is necessary if we want it
short.What exactly are you doing which forces you to do ugly hacks like this. Some of us may want to take a stab at it.
