I have bash set to noclobber mode in my .bashrc - from the bash man page:
set [--abefhkmnptuvxBCHP] [-o option] [arg ...]
...
-C If set, bash does not overwrite an existing file with
the >, >&, and redirection operators. This may be
overridden when creating output files by using the
redirection operator >| instead of >.
Sometimes I want to override this behavior, so I use the >| redirection operator to do this. But sometimes I want to redirect both stdout and stderr to a file. The file may already exist, so I may want to clobber this file. Given the documented operators >& and >|, I would expect there also to be a >|& or >&| or &>| operator, which would redirect both stdout and stderr to the file, with a forceful overwrite. But I am unable to find such a single operator:
$ ls file.txt missing
ls: missing: No such file or directory
file.txt
$ ls file.txt missing >& output.txt
bash: output.txt: cannot overwrite existing file
$ ls file.txt missing >&| output.txt
bash: syntax error near unexpected token `|'
$ ls file.txt missing >|& output.txt
bash: syntax error near unexpected token `&'
$ ls file.txt missing &>| output.txt
bash: syntax error near unexpected token `|'
$
I know I can do this with a combination of >| and 2>&1, but would rather be able to do this with a single operator:
$ ls file.txt missing >| output.txt 2>&1
$ cat output.txt
ls: missing: No such file or directory
file.txt
$
Does such an operator exist, documented or otherwise?
I notice that there appears to be a bit of a precedence to what I am asking about - specifically in the "append" versions of these operators. In bash 4, the &>> operator was introduced, which allows stdout and stderr to be appended to the output file. But there appears to be no "clobber" version of this. How can I redirect and append both stdout and stderr to a file with Bash?
