I have a program which I want to have a bi-directional pipe to (i.e both write and read). I am unable to tee it to a file and then read the file, so reluctantly started to investigate the IPC modules. I have a snippet of code here, which again works (sort of), just not in the way that I need...
#!/usr/bin/perl -w use IPC::Open2; use IO::Handle; $program="maxent"; ($reader, $writer) = (IO::Handle->new, IO::Handle->new); open2($reader, $writer, $program); chomp($out = <$reader>); close $reader; close $writer; print STDOUT $out."\n"; werd@psw283~/temp$ ./pipe.pl Format USR is implimented (True/False) = T werd@psw283~/temp$ forrtl: severe (24): end-of-file during read, unit 5, file stdin cannot read in maxent As you can see, the line beginning with Format USR..... does indeed read correctly. However, there are many more lines where this one has come from and reading them all is the idea. Any clues?
