I don't quite understand how the computer reads this command.
cat file1 file2 1> file.txt 2>&1
If I understand, 2>&1
simply redirect Standard Error to Standard Output.
By that logic, the command reads to me as follows:
concatenate files
file1
andfile2
.send
stdout
from this operation tofile.txt
.send
stderr
tostdout
.end?
I'm not sure what the computer's doing. By my logic, the command should be
cat file1 file2 2>&1 > file.txt
but this is not correct.
