Silly me! Here is an even simpler test. $ mkdir -p $HOME/bin $ cat >$HOME/bin/pathtrial1 <<\EOF #!/bin/sh echo hello from pathtrial1 EOF $ chmod a+x $HOME/bin/pathtrial1 $ pathtrial1 hello from pathtrial1 That sets up the test as before. Then simply start up dash with that PATH. I use 'env' here as the portable way to invoke a command with a specified environment but avoiding shell aliases and so forth and regardless of your shell being csh or some such. $ env PATH='~/bin:/usr/bin:/bin' /bin/dash Then try calling programs from $HOME/bin. They won't be found. $ pathtrial1 /bin/dash: 1: pathtrial1: not found $ echo $PATH ~/bin:/usr/bin:/bin Bob
