Question
Shell
Which symbol should I use to redirect the error output to the standard output?
Solution
In a Unix-like shell, you can redirect the error output (stderr) to the standard output (stdout) using the following symbol:
2>&1
Here's how it works:
2
refers to the file descriptor for standard error (stderr).>
is the redirection operator.&1
indicates that we want to redirect it to file descriptor 1, which is standard output (stdout).
Example Usage:
If you have a command that may produce errors, you would use it as follows:
some_command 2>&1
This command will merge both the standard output and standard error streams, allowing you to see all output in a single stream.
