EVPATH=/home/joe/.config/env
EVPATH is the directory or list of directories where ev will search.
PATH can be a name of a file/directory in EVPATH or a path to a file/directory.

By default, EVPATH is $XDG_CONFIG_HOME/env.

Example

$ env | grep FOO
$ env | grep BAR
$ tree ~/.config/env/foo/
/home/joe/.config/env/foo/
├── FOO
└── BAR

0 directories, 2 files
$ ev foo
FOO
BAR
$ env | grep FOO
FOO=foo123
$ env | grep BAR
BAR=bar
$ ev -u foo
FOO
BAR
$ env | grep FOO
$ env | grep BAR

Executables

If a file is executable, ev will run the file and store the result.

$ echo >IP "\
   #!/bin/sh
   curl -s ifconfig.co"
$ chmod +x IP
$ ./IP
8.8.8.8
$ env | grep IP
$ ev IP
