Linux labs: Fixing issues with 'fish' shell in the home directory
How to fix a common problem for users of the 'fish' shell on the linux labs.
If a user has an error in their terminal that looks something like the following:
error: Unable to rename file from '/filespace/b/bucky/.config/fish/fishd.tmp.RDqhYw' to '/filespace/b/bucky/.config/fish/fish_variables': Device or resource busy
Then they are likely using `fish` as their login shell for the Linux lab machines and are having errors with their NFS-mounted home directories. A fix for this issue is as follows (run the following commands, one by one, from a terminal that is NOT currently running the `fish` shell):
- $ tmphome=$(mktemp -d)
- $ export REAL_HOME=$HOME
- $ HOME=$tmphome fish
- > $ cp $HOME/.config/fish/fish_variables $REAL_HOME/.config/fish/fish_variables
- > $ exit
- $ rm -rf $tmphome
- $ fish
Then everything should work without any errors.
