Answer by jlettvin for BASH script to set environment variables not working

I often want to set an environment variable without hassle.

Here is what I add to my .bashrc to implement this convenience.

defect() {
    if [ $1 ] && [ -z $2 ]
    then
        eval 'export DEFECT=$1'
        return 0
    else
        echo 'Usage: defect {number}'
        return 1
    fi
}
