Hi, I'm not sure whats going wrong here, but I'm trying to use the system command supplied by (require scheme/system) or (require (lib "process.ss" "mzlib")) It seems to get a different version of $PATH on my osx machine this code; ;#lang scheme/base ;(require scheme/system) (require (lib "process.ss" "mzlib")) ;(system "svn add svn-commit.scm") (system "echo $PATH") (system "svn commit  -m \"auto-commit\"") returns this; Welcome to DrScheme, version 372 [3m]. Language: Pretty Big (includes MrEd and Advanced Student) custom; memory limit: 128 megabytes. /usr/bin:/bin:/usr/sbin:/sbin #t /bin/sh: line 1: svn: command not found #f > but when I use the terminal I get $ echo $PATH /opt/local/bin:/opt/local/sbin:/sw/bin:/sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin I'm assuming that; 1. $PATH is [normally] the same for bash and /bin/sh ie $ /bin/sh sh-2.05b$ echo $PATH /opt/local/bin:/opt/local/sbin:/sw/bin:/sw/sbin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin 2. the system command supplied by (require scheme/system) and (require (lib "process.ss" "mzlib")) is the same It seems I am wrong about 1 and the /etc/profile and .profile are bash specific and don't run for /bin/sh and therefore my commands don't have access to the modified path. I'd rather not hard code the path, as I want this to run on a variety of machines; - does anyone have any suggestions on how best to make this work?
