$ cat data.txt | grep "No such file"
However, this does not redirect the errors. So, if the file does not exist, the grep command above will not return a match.
What if you want to redirect and process both errors and normal outputπ€
This is where this "|&" redirection operator comes in handy.
This operator sends both the standard output (stdout) and standard error (stderr) of the first command over a pipe to the standard input (stdin) of the second command. Take a look at this example:
$ cat data.txt |& grep "No such file"
Notice the difference, the grep command was able to get a match.
The "|&" operator in bash is a shorthand for the "2>&1 |" redirection operator.
$ cmd-1 2>&1 | cmd-2
