Why does my .bashrc file not work?
Sometimes, customers upload a file named “.bashrc
” to add aliases and other shell commands that they want to use when making ssh connections.
An ssh connection is actually a bash “login shell”, though, so you need to put the commands in a file named “.bash_profile
” instead of “.bashrc
”.
The difference is subtle and often confusing. If you want more details, the “INVOCATION” section of man bash explains in technical terms why it’s like this. And a Google search for .bash_profile .bashrc will show lots of discussions people have had about it.
Note that some people — and even some Linux distributions, by default — “cheat”, by simply sourcing .bashrc from within .bash_profile. So if you’ve done it before with .bashrc on another system and it worked, it’s almost certainly because someone already put a .bash_profile file there that contained something like:
. ~/.bashrc
However, we use Debian Linux, which doesn’t do that by default.
To solve this, just put your shell commands and aliases in a file named “.bash_profile
” instead of “.bashrc
”, and it will probably work as you expect.
