Whether this is true or not I cannot begin to guess because I can't see your computer from here, so have no more than a vague description that you "might" have done something in an odd way.

Is it something you did? Maybe. Maybe not. Post the code.

The only reference to fork is, ichpid = fork(); and then ichpid is used.

I can't post all of this code without various kinds of permission. I have a version of it that has been cleared, but it will take a bit to add the linux components and such. The cleared version is the widows code.

I just don't under stand why it doesn't print to the terminal. I have tried in CentOS, and Ubuntu and get the same results. There are no fortran header files, so there can't be a missing include, even if the compiler would let it go. Am I missing a compiler flag or something like that? I could post the make file if that would help. The only difference between the windows and linux versions are the src files for the parent and child main functions, and an auxilary functions src file. That is a very small part of the code and the rest is the same for win/lin. I don't really understand why this works in cygwin bash, but not linux bash. Both are using the gcc3.4 family.

set_color

set_color(1)                                                           fish                                                           set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
