There are preferred recommended way to edit some files. For example,
editing crontab should be done with "crontab -e", editing /etc/passwd
should be done with vipw, editing /etc/groups should be done with vigr,
editing the sudoers file should be done with visudo. The common
property these techniques share is that they put a lock on the file
that is respected by other programs that may also modify these files,
e.g. passwd; the lock makes sure that changes are applied in the right
order and not overwritten.
Especially for single-user systems - these aren't that important.
