First, can you get the sed command to work at the cygwin prompt? If not, it's quite possible that the environment from which your running the program does not have sed in its' path. You should also try this:=20 `echo "yada" | sed 's/:/-/g'` The best solution would be to convert the ':' chars to '-' chars in your C program.
