Which shows up that way in 'printenv', and requires the use of $$FOO to dereference? (Some quick testing with bash 4.4 seems to indicate that it *really* doesn't want to see $ as the first character of a variable name. I had to use 'env' to jam it in there, and accessing it was.. problematic [~] env '$FOO=27' printenv | grep FOO $FOO=27 [~] env '$FOO=27' bash [~]1 printenv | grep FOO $FOO=27 [~]1 echo $FOO [~]1 echo $$FOO 9305FOO [~]1 echo $\$FOO $$FOO [~]1 eval echo \$$FOO $ [~]1 eval echo \$\$FOO 9305FOO [~]1 exit
