#243914 — bashrc problem

[Multipart message — attachments visible in raw view] — view raw

Hello list

I have a .bashrc file in my home dir, whose content is shown as follows.

But every time I log into the system, I have to source this file by hand.

$ which scala
/usr/bin/scala

$ cat .bashrc
#THIS MUST BE AT THE END OF THE FILE FOR SDKMAN TO WORK!!!
export SDKMAN_DIR="$HOME/.sdkman"
[[ -s "$HOME/.sdkman/bin/sdkman-init.sh" ]] && source
"$HOME/.sdkman/bin/sdkman-init.sh"

$ . .bashrc
$ which scala
/home/xxx/.sdkman/candidates/scala/current/bin/scala


How can I make it take effect automatically after I login the system?

Check whether you have either ~/.bash_profile or ~/.profile.

If ~/.bash_profile, the line
  . ~/.bashrc
will suffice.

If ~/.profile, use
  # if running bash
  if [ -n "$BASH_VERSION" ]; then
      # include .bashrc if it exists
      if [ -f ~/.bashrc ]; then
          . ~/.bashrc
      fi
  fi
in case you someday want to try other shells.

Do you mean if .bash_profile exists, .bashrc will be ignored?

Thanks.

Sometimes.  From `man bash`:
  When bash is invoked as an interactive login shell, or as a
  non-interactive shell with the --login option, it first reads
  and executes commands from the file /etc/profile, if that file
  exists.  After reading that file, it looks for ~/.bash_profile,
  ~/.bash_login, and ~/.profile, in that order, and reads and
  executes commands from the first one that exists and is readable.
  [...]
  When an interactive shell that is not a login shell
  is started, bash reads and executes commands from
  /etc/bash.bashrc and ~/.bashrc, if these files exist.
