Sorry for the delay in responding, I had to go to the doctors. I have been trying to get rid of an annoying case of bronchitis. It would help if it would just get warm some time soon.

Did I miss something somewhere? I thought I answered everything.

Maybe I wasn't clear in the original post. The issue is not with the output that the program is supposed to make, which goes to the output file (and is working properly), but with additional print statements that I have added for debugging purposes. Since I can't get fortran to work with gdb, I am stuck without a debugger/IDE and have to debug by adding print statements to the code in very, very, old school fashion.

I normally just add,
print*, (fortran)
std::cout << (cpp)
and get the output I need.

This is the code that I can't get to print to the terminal in linux, but prints fine in windows. The normal output file is fine under both platforms.

I would normally just run,

./appName -i inputFile -o outputFile
./appName -i inputFile -o outputFile > stdout.txt (for large output)

and could look at the debugging output in the shell. The program runs, the output is fine, but there is nothing in the shell, or output fie (I tested both).

I have also tried,

./appName -i inputFile -o outputFile &> stdout.txt

in case the output was somehow going to stderr.

The only thing I can think of is that cout is not going to the terminal in this case, but has been redirected elsewhere, like it might be if you were running a gui. I will look carefully through the code and see if I can spot anything that might be a likely candidate. It was also suggested that the problem may be with flushing the o/p buffer, so I will also try adding some cin statements and see if that changes anything.

NAME
mboxcheck - MBOX mail checking program. SYNOPSIS
mboxcheck [options] [file [...] ] DESCRIPTION
MBOXcheck is a simple mailbox checker. Give some options and at least one mailbox file as an argument and it will print some status of how many messages there are and which status they have. OPTIONS
--help The help text. -h --version The version information about this tool. -V --showon [v][?] When to show a mailbox in the list. [v] - verbose, always show. [?] - show when count is above 0 for the below types, see --show what for more information about that. The default is to trigger only on new messages (--showon new). --show [n][s][r][o][a][d] What counts to show. The caracter in the bracket is the short form. The what string can be comma separated to specify more than one option. Multiple --show options will add more (and will not remove shows). [n] - new (new messages) [s] - seen (seen but not read messages) [r] - read (read and answered messages) [o] - onlyread (just read messages) [a] - answered (answered messages) [d] - deleted (deleted messages) The default is to show new and seen messages (--show ns). --recurse This option will tell the tool to recurse into -R -r subdirectories. --nosymlink Tell the program to ignore symlinked files and directories. --cachedir dir A temporary directory to use for speedup cache (default ~/.mboxcheckcache) --nocache Do not use a temporary directory. CACHE
The cache file is named after the path to the file with slash caracters '/' replaced with two commas ',,'. The content is a list of comma separated values; last position, new, seen, only read, answered and deleted mail. AUTHOR
