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. The second exec copies file descriptor 3 to standard output again, and then closes file descriptor 3. This is a bit open ended. It can be described at a C code level or at the shell command line level.
Why do I get error trying to exec’cc1plus’?
I had the same issue when forking with ‘python’; the main reason is that the search path is relative, if you don’t call g++ as /usr/bin/g++, it will not be able to work out the canonical paths to call cc1plus. 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.
