How to set an environment variable in bash?
The syntax in bash for setting an environment variable is as follows.
export VARIABLE=value
Note that there is no space among the variable, the equals sign (“=”) and the value. If the value has spaces, the value should be put in quotes.
To check it:
echo $VARIABLE
To show all environment variables set, run env, set (bash build-in command) or printenv.
To make the variable settings effect for each bash shell, put the exporting command to your ~/.bashrc
, the individual per-interactive-shell startup file.
