Hi Guix,

Today I had the following issue and I'm wondering if other Guix users
have this problem too.

Start a SBCL REPL and run:

--8<---------------cut here---------------start------------->8---
(run-program "ls" '("-la")
             :search "/run/current-system/profile/bin"
             :environment '("TIME_STYLE=full-iso")
             :output *standard-output*)
--8<---------------cut here---------------end--------------->8---

This fails on my side, but I was told it works on other GNU/Linux
distros.  Can you reproduce it?

I find this quite strange since the following Bash works for me:

--8<---------------cut here---------------start------------->8---
TIME_STYLE=full-iso /run/current-system/profile/bin/ls -la
--8<---------------cut here---------------end--------------->8---

Thank you.

Hi,

The documentation of the 'run-program' function indicates:

--8<---------------cut here---------------start------------->8---
:SEARCH
   Look for PROGRAM in each of the directories in the child's $PATH
   environment variable.  Otherwise an absolute pathname is required.
--8<---------------cut here---------------end--------------->8---

which means that it should be used either like this:

--8<---------------cut here---------------start------------->8---
(run-program "ls" '("-la")
             :search t
             :environment '("TIME_STYLE=full-iso"
                            "PATH=/run/current-system/profile/bin")
             :output *standard-output*)
--8<---------------cut here---------------end--------------->8---

or like this:

--8<---------------cut here---------------start------------->8---
(run-program "/run/current-system/profile/bin/ls" '("-la")
             :environment '("TIME_STYLE=full-iso")
             :output *standard-output*)
--8<---------------cut here---------------end--------------->8---
