💡 Hint

Common Mistakes

Using 2> redirects error separately, not combined.

Using 2>&2 does nothing as it redirects error to itself.

2>&1 redirects standard error to the same place as standard output.

4fill in blank

hard

Fill both blanks to redirect standard output to a file and standard error to another file.

Bash Scripting

command [1] out.log [2] err.log

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 2>> for standard output is incorrect.

Using > for errors does not redirect error stream.

> redirects standard output, and 2> redirects standard error.

5fill in blank

hard

Fill all three blanks to redirect standard output to append to a file, standard error to append to another file, and combine both outputs to the console.

Bash Scripting

command [1] out.log [2] err.log [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using > instead of >> overwrites files.

Not using tee means output won't show on console.

>> appends standard output, 2>> appends standard error, and | tee -a shows output on console while appending.
