afniSwitchFromRepo.sh - temporarily switch from the neurodebian repo version of AFNI to a local alternative

afniSwitchFromRepo.sh

#!/bin/bash

# afniSwitchFromRepo.sh
#
# A script to tempoarily switch the user from the neurodebian repo version of
# AFNI to a local alternative install (e.g., /opt/abin). Works in combination
# with afniSwitchToRepo.sh


# Specify the parent directory of alternative AFNI's binaries:
# e.g., afniAlternativePath=/opt/abin
afniAlternativePath=/opt/abin


# Clear any AFNI environmental variables:
unset `env | awk -F= '/AFNI/ {print $1}' | xargs`


# Backup the user's current $PATH to an environmental variable so we can switch back
# to it later:
export afniRepoVersionOfPATH=${PATH}


# Prepend the path of the alternative (non-repo) version of afni to the user's $PATH:
export PATH=${afniAlternativePath}:${PATH}


# Print afni version info to the terminal:
echo ""
