Use a Preceding Space in Terminal to Hide from History

This is a trick to running commands that you don’t want to be saved in your history.

You may want to run a command that isn’t stored in your history. You can do this with a preceding space.

# no preceding space
someCmd --key ABC123

history
# 98 ...
# 99 someCmd --key ABC123

# with preceding space
anotherCmd --key ABC123
cd ~

# notice `anotherCmd` is missing
history
# 98 ...
# 99 someCmd --key ABC123
# 100 cd ~

A common scenario may be when using sensitive values a single time (i.e. where you don’t want to take the time to set environment variables).
