lb-run shell usage

[pseyfert]

Starting shells with lb-run Project version shell is not unproblematic. (the login scripts get sourced again after lb-run defined the correct environment, resulting in bad paths prepended to e.g. the python path). My current workaround is

lb-run Project version shell -f
source .shellrc

This gets the user defined goodies without the system defined problems. Is there a oneliner solution?

[pseyfert]

I usually run a self built zsh instead of the standard login shell. So to avoid the problem in the first place I built zsh with --disable-etc. The environment in such a shell is about identical to that defined by lb-run (up to SHLVL and _).

I mark the issue for now as won't fix despite the fact that the solution is terribly suboptimal.

NB: subshells started this way come without (LbLogin) aliases. i.e. your own ~/.zshrc aliases are defined, but SetupDaVinci is not. For lb-run shells this hardy matters (won't do SetupX in those) but if one just starts a self-compiled shell to have a better shell these aliases will be missed.

Discussing the matter on stackexchange I am tempted to:

• not log in to lxplus with ssh -t lxplus /afs/cern.ch/user/p/pseyfert/.local/bin/zsh-without-etc because collecting all the desired bits from /etc will be a mess (mostly if one would only collect LbLogin. just starting from /etc/z* based on SHLVL might even work). and building two shells (one with and one without etc) is a comparable mess
• instead one could make an alias or function (not sure about pros and cons here) to define alias myzsh="alias -L > ~/.tmpaliases; /..../zsh" and alias mylbrun="alias -L > ~/.tmpaliases; lb-run" (NB: checking if ~/.tmpaliases and sourcing&deleting is in my ~/.zshrc) (NB2: both without -g) (NB3: this might mess up the lb-run completion, immediately expanding it might be needed)

the second hack actually brings us back close to the initial one-liner problem -- doing some sourcing based on quick diagnosis in ~/.zshrc, just that all the /etc is left and locked out.
