# There isn't a built-in flag yet, but you can use

# Edit[0]: I've noticed that this fails when 'pip freeze' lists a package that cannot be installed from pypi anymore.
# Edit[1]: the command used to read "... | xargs echo pip install...", I've removed the "echo" so that the command actually performs the upgrade the install.
# Edit[2]: added a grep to skip "-e" package definitions, as suggested by @jawache
# Edit[3]: With newer versions of pip you can list outdated packages, though not in "requirements" format this possibility is actually built-in: pip list --outdated
