osx - how to set up the environment variables on mac os x -

-

i trying download myrna tool on mac os x. 1 of procedures on installation, "set myrna_home environment variable point extracted directory (containing myrna_emr)"

so tried way

echo "export myrna_home=/.../....directory/.." >> ~/.bashrc

but seems not work.(when type echo myrna_home in command line, there nothing or when type printenv myrna_home not come out.)

anyone knows how set env vars??

thank you,

there several ways that. 1 adding variable ~/.bash_profile file.

example:

myrna_home=/whatever/you/want/ export myrna_home

then can try if works logging in again , trying on terminal:

$ echo $myrna_home

it should print whatever set mryna_home on ~/.bash_profile.

if want environment variable available users, can change /etc/bashrc file. prefer changing 1 users' environment.
