Bash: How to Redirect std out and error Stream into a File?

edit

o redirect both the standard output (stdout) and standard error (stderr) streams into a file, you can use the following syntax in the bash shell:

command > outputfile 2>&1

command: Replace this with the command you want to run.

: This symbol is used for redirecting the standard output (stdout) to a file. outputfile: Replace this with the name of the file you want to store the output and errors in. 2: This is the file descriptor for standard error (stderr). &1: This means "redirect the standard error (2) to the same destination as the standard output (1)". For example, if you want to run a program called my_program and store both its standard output and standard error in a file called output.txt, you would use the following command:

my_program > output.txt 2>&1

Alternatively, you can use the shorthand &> to achieve the same effect:

my_program &> output.txt

This command will also redirect both the standard output and standard error to the specified file.
