I want to redirect both standard output and standard error of a process to a single file. How do I do that in Bash?

Understanding the concept of redirections and file descriptors is very important when working on the command line. To redirect stderr and stdout , use the 2>&1 or &> constructs.
1 "Standard output" output file descriptor. The expression 2>&1 copies file descriptor 1 to location 2 , so any output written to 2 ("standard error") in the execution environment goes to the same file originally described by 1 ("standard output").
Take a look here. It should be:
yourcommand &> filename It redirects both standard output and standard error to file filename.
