How to set different environment variables for different hosts

Question

We are using NIS and Automount for *nix developing hosts. So I can login any host with the same identity and same home directory.

I hope to set different environment variables when login different hosts. For example, I want to set the LD_LIBRARY_PATH with some value when login the solaris host. However I don't set it when login the linux host.

How should I do?

Answer 1

Use conditionals in your ~/.profile.

case `uname` in
  Solaris)
    PATH=/usr/xpg6/bin:/usr/xpg4/bin:$PATH
    LD_LIBRARY_PATH=$HOME/lib/solaris
    export LD_LIBRARY_PATH;;
esac

You might also want to set some aliases and other shell settings differently. These go into your ~/.bashrc or ~/.zshrc.

case `uname` in
  Solaris)
    alias df='df -k' du='du -k'
    alias ls='ls -F';;
  Linux)
    alias ls='ls --color';;
esac

Answer 2

I am assuming you use bash as your shell.

Edit your user's ~/.bashrc and add the following line

[[ "$(uname)" != "Linux" ]] && export LD_LIBRARY_PATH=/solaris_path:$LD_LIBRARY_PATH
