I am using a Macbook Pro to do some Objective-C study. Instead of using Xcode I choose to use terminal, as I don't want to create one project for each main program. The terminal works find like the one under Linux, except one thing: whenever I execute an executable file, instead of displaying the output from the start of the next line, it always displays the date, the time and the program name first before displaying the output of my executable. I find it kind of disturbing, as it occupies more than half of the terminal width. Is there any way to remove these redundant stuff from the display?
Are you referring to a command that you entered at the shell prompt? On Mac OS X the default shell is bash, and by default it doesn't display anything extra when invoking a command entered at the shell prompt. If you're seeing something like this $ somecommand Thu Aug 11 18:54:10 somecommand command output then either this is displayed by the command you're running or the shell must have been customized on your system. If this happens for every command, including things like 'ls' and 'cat', then look for ~/.bash_profile, ~/.bashrc and other standard shell startup scripts to see if someone has customized the shell. On the other hand, if you're seeing something like this Last login: Thu Aug 11 18:59:12 on ttys001 hostname:~ username$ somecommand command output as soon as you open the terminal, then there are a few different ways to cause this to happen: • The terminal settings profile has been customized to run 'somecommand' when opening the terminal. Look in Terminal > Preferences > Settings > [profile] > Shell > Startup > Run command.
