To export the correct environment variables under bash. Copy the file /usr/local/ferret/bin/ferret_paths_bash_template to /usr/local/ferret_paths then edit it to perform the following changes:
# You may want to customize the pathname of the `ferret' directory: export FER_DIR=/usr/local/ferret # The environment variable FER_DSETS should be the pathname of # the directory named `fer_dsets' you created to install the FERRET program. # !!!! You must customize the following line: # This directory will contain FERRET demonstration data files (30+ Mbytes) export FER_DSETS=/home/guillaume/Projects/ferret/fer_dsets # System Manager: Check this PATH modification for your system security. # If you prefer not to modify PATH here you may comment out the following few # lines and execute the file $FER_DIR/bin/install_ferret_links wich will # create ferret links in /usr/local/bin. export PATH="$PATH:$FER_DIR/bin"
