tip: getting the files which might be affected by a merge

[Arne Babenhauserheide]

Hi,

A collegue asked me how to get all the files which could be affected by a merge. With some help from killerix and Anoia in #mercurial and “set operations in the unix shell” (http://www.catonmat.net/blog/set-operations-in-unix-shell-simplified/), I came up with this clean solution:

    hg diff -r "ancestor(.,other) -r . --stat | cut -d "|" -f 1 | sed "s/ *$//" > /tmp/1
    hg diff -r "ancestor(.,other) -r other --stat | cut -d "|" -f 1 | sed "s/ *$//" > /tmp/2
    comm -12 <(sort /tmp/1) <(sort /tmp/2)

I thought it could be interesting for others, too :)

Best wishes,
Arne

PS: I also addid it to the wiki:

A man in the streets faces a knife.
Two policemen are there it once. They raise a sign:

    “Illegal Scene! Noone may watch this!”

The man gets robbed and stabbed and bleeds to death.
The police had to hold the sign.

…Welcome to Europe, citizen. Censorship is beautiful.
