$:hg ci -m 'copied single file from from-branch to to-branch
7. Dirty merge If both branches have made changes to a file that you want to keep, a dirty trick would be to create a merge of the two branches using hg merge, possibly/probably on still another branch, check that in, and then copy a single file between the merge and the to-branch(Reference: Stackoverflow)
$:hg update -r to-branch
$:branch merge-branch
$:hg merge -r from-branch
$:hg ci -m 'temp merge to be discarded"
$:hg update -r to-branch
$:hg revert -r merge-branch single-file
$:hg ci -m 'merged single-file from from-branch to to-branch"
$:hg strip merge-branch
