Expect cannot find commands

So, after i have chrooted into /mnt/lfs and am installing binutils, there is a test asking to check whether ptys are set up correctly using

expect -c "spawn ls"
This fails not because there are no available ptys, but because expect cannot find ls.

LS is in /tools/bin, which is in $PATH

I can execute this correctly by typing:

expect -c "spawn /tools/bin/ls"
Where is my mistake?

How have you verified the PATH that expect actually sees?

Yeah, so it turns out that i forgot to export PATH. PATH looked fine when i did echo $PATH, but it was not available to everything else.

Lesson learned: don't use echo to test environment variables
