How to stop exec 1 > file in Linux?

The first exec copies the original file descriptor 1 (standard output) to file descriptor 3, then redirects standard output to the named file.

You may have this issue as well if you have environment variable GCC_ROOT pointing to a wrong location.

Which is the correct way to use exec 1 file?

Q2: exec 1>file is a slightly more verbose way of doing exec >file which, as already stated, redirect stdout to the given file, provided you have the right to create/write it. The file is created if it doesn’t exist, it is truncated if it does. exec 1>&- is closing stdout, which is probably a bad idea in most situations.

Which is the equivalent of exec 1 > / dev / tty?

As I wrote, exec 1>/dev/tty and exec >/dev/tty are exactly equivalent so save one keystroke and use the latter. On the other hand, while exec >/dev/tty is portable, exec 1>/dev/pts/0 is not and happen to do the same in your experiment only by chance. That wouldn’t work with another terminal window and might not work either with a different machine.
