In praise of --dry-run
At my work I've gone through and setup a variety of "replacement" commands for commands that may have dire impact on production systems. All of these replacement commands dry run by default (or fake dry run/try to create a dry run the best they can) and require a "--do-it" (think emperor palpatine voice) flag to do the intended operation. I've had multiple coworkers thank me for this setup as it's saved people from silly typos and mistakes, one such being the different handling of programs in the use of and ending "/" in folders. ex. "/etc" is different than "/etc/" sometimes for certain operations.<p>I'd like to one day see a global flag on operating systems to dry run nearly all commands that changed anything.
