Description
Rather than adding >> something after every single line, you can simply group the relevant commands and redirect the group. Now the file has to be opened and closed only once, which can be a performance gain.
Bad Practice
echo foo >> file
date >> file
cat stuff >> file
Recommended:
{
echo foo
date
cat stuff
} >> file
