Answer 1

In case TortoiseHg is used, right-click the revision row in the Workbench and select "Copy hash" (as per documentation).

Answer 2

Try:

hg id -i

Example:

$ hg id -i
adc56745e928

Answer 3

hg --debug id -i

This will output the long hash, with a plus if there are uncommitted changes.

Answer 4

Summarising the answers and their responses, it seems that this is the best way to print the unique (not short form) identifier of the current version:

hg log -l 1 --template '{node}\n' -r .

Answer 5

You can use --template with the parent command, I use this to get the long hash:

hg parent --template '{node}'

Answer 6

The most specific non-DEPRECATED command which due to the presence of --template can print only revision information if that conciseness is required (as implied by the question):

hg log -l 1 -b . -T '{rev}:{node|short}\n'

Or for unique long form of hash:

hg log -l 1 -r . -T '{node}\n'

The -b . or branch(.) (dot for branch name) means the current working directory branch and -r . means the current working directory revision, which is documented in hg help revsets and hg help revisions.

Note if there is an uncommitted merge, the . (dot) only displays the first parent of two parents of the working group.
