SC2129

Consider using { cmd1; cmd2; } >> file instead of individual redirects.

Problematic code:

echo foo >> file
date >> file
cat stuff  >> file

Correct code:

{
  echo foo
  date
  cat stuff
} >> file

Rationale:

Rather than adding >> something after every single line, you can simply group the relevant commands and redirect the group. So the file has to be opened and closed only once and it means a performance gain.

Exceptions:

This is mainly a stylistic issue, and can freely be ignored.
