I want to add /data/biocs/b/bio425/bin to the $PATH variable in the .bash_profile file (using vi or emacs) What I have done so far is vi .bash_profile and then I attempted to add /data/biocs/b/bio425/bin to my SPATH # bash-profile # Get the aliases and functions if [f /.bashrc then fi # User specific environment and startup programs PATH-$PATH: $HOME/bin:../../bio425/bp-utils export PATH PATH-$PATH: $HOME/bin:../../data/biocs/b/bio425/birn ./.bashrc export PATH I then saved and of course sourced the file. Next I tried to run the command long-orf mystery_seqi , but I got long-orf: command not found AmI doing something wrong with my SPATH variable
