Mercurial log with one-liners

Question

The regular hg log command gives output with at least 4 lines per changeset. For example

changeset:   238:03a214f2a1cf
user:        My Name 

        

Answer 1

 hg log --style compact

You can also use templates to display log out in different formats

hg help templates

In your case if you want to display only node ids do something like this

hg log --template "{node}\n"
