[Solved] Would pipe work better with this command
Hi again, have a script that I would like run, but before I can run it I need to strip out the windows \r end of lines.
I have put the command into a text file and set the command to run every 10 seconds the coomand I use to do this is
Code:
while sleep 10; do /Volumes/AraxiVolume_HW07376_J/OPS_OutPuts_TimeStampText_For_Naming_Work_Folder/OPS_TempFolderForFiringTrigger/GOLDEN.TERM; done

The command that its firing is in a text file called GOLDEN.TERM
this is the code for that file
Code:
cr=$(printf "\r")
sed -i "" -e s"/$cr//g" /Volumes/AraxiVolume_HW07376_J/OPS_OutPuts_TimeStampText_For_Naming_Work_Folder/OPS_OutPuts_TimeStamp_SED_INPUT/[0-9]*-OPS_OutPuts_TimeStamp 
/Volumes/AraxiVolume_HW07376_J/OPS_OutPuts_TimeStampText_For_Naming_Work_Folder/OPS_OutPuts_TimeStamp_SED_INPUT/[0-9]*-OPS_OutPuts_TimeStamp

That the command does is strips away the windows \r and save over the original file and then executes the original file with out windows \r.
What I would like to do is pipe the the output from the command that strips away the windows \r through to the shell again without saving the file to disk.
The commands I have work in the terminal put trying to execute as them from a file does not.
Does any one have an idea how I can make this work?

Member Function Documentation
   static std::string shevek::process::run (std::string const &command, std::string const &sh) [static]
       Run a process and return its output. A convenience function for running a process and catching its standard output in a string. This blocks
       until the process has exited.

   static Glib::RefPtr<process> shevek::process::shell (std::string const &command, boolpipe_stdin = true, boolpipe_stdout = true, boolpipe_stderr
       = true, std::string const &sh = '/bin/sh') [inline, static]
       Run a string with the shell. Note that the process is forked from the shell, and so does not get killed when the process goes away.
