Redirect output of a command to files with ">" or ">>"
> = overwite file. For example,
echo "hello world!" > helloworld.txt
>> = append to end. For example,
echo "hello world!" >> helloworld.txt
You can use the same technique to get rid of messages by redirecting them to /dev/null by entering
There are two types of messages:
- Standard output (stdout) - the normal output of the execution of a program.
- Standard error (stderr) - the output when the program encounters errors.
You can redirect them together or separately:
"command >/dev/null" will redirect stdout only. "command 2>/dev/null" will redirect stderr only. "command &>/dev/null" will redirect both stdout and stderr.
Redirecting input: stdin can be redirected using "<" sign. For example a program can get its input from a file:
"command < filename"
Redirecting standard input from a "here string"
command <<< "string to be read as standard input"
