That's a valid point, but this should be doable in pure shell. It might even be faster (untested), and avoids needless forking. Most importantly, it's fun. > . /etc/environment > export `cat /etc/environment | cut -d= -f1` ‘cat file | ...’ can be replaced with ‘... < file’; ‘cut’ isn't needed since export accepts ‘VAR[=value]’ arguments[1][2]. You've just imported ‘/etc/environment’ on the previous line, and the values haven't been modified. Hence, the two lines above can be written as: while read line; do export "$line"; done < /etc/environment I don't know if Guix even cares about non-bash shells, but this should™ work in all POSIX®-compliant ones[4]. It's also more readable. Thoughts? Gotchas? Kind regards, T G-R [1]: http://pubs.opengroup.org/onlinepubs/009696799/utilities/export.html [2]: even if it didn't, section 2.6.2 of [3] has got you covered [3]: http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html [4]: which reminds me to finish packaging ash for Guix
