Regarding alias ssh=’ssh -AX’ alias ls=’ls –color=auto’ Let me quote the Mercurial manual: > It is possible to create aliases with the same names as existing commands, which will then override the original definitions. This is almost always a bad idea![0] I was recently bitten by this when running a build on a new machine. I was doing a log -r "$revision" and instead of getting one commit message (as usual), I was getting the entire log history up to $revision. I managed to find that Mercurial had made a breaking change[1] so that `log -fr` would now have the observed behavior. But I was only running `log -r`! But on the old machine, I had in my .hgrc the alias log=log -f To top it off, I also had a comment with the above quote that this is "almost always a bad idea!" Consider me burned!
