Help in bash

Did you know that bash has its help too? Just simply type in:


It will show the version number and the list of its internal commands.

This thing is so trivial that in my opinion most people don’t even think of it. I just found it by accident too :)

Update (20110416)
If you only want to figure out the version number of bash, here are the alternatives:

  • bash --version
  • “\C-x\C-v”, i.e. CTRL+X CTRL-V (see bind -P for full list of shortcuts)
