comment is it possible to open a new shell from a shell and switch between them?
@honk Thanks. Online man pages didn't mention suspend, but indeed it's there in bash 3.2. gnu.org/software/bash/manual/html_node/Bash-Builtins.html

comment How do I make sudo preserve my environment variables?
Not sure why you have to modify env_keep to keep PYTHONPATH. If !env_reset is in effect and there are no env_delete entries, that should be sufficient AFAIUI.

What about env_delete? Also, man page says: Note that many operating systems will remove potentially dangerous variables from the environment of any setuid process (such as sudo).

If sudo was compiled with --with-secure-path, that would be modifying PATH, but the docs don't say it touches LD_LIBRARY_PATH.

comment how do I pipe to the “for” command?
@barlop, I just open up a command prompt, type help | more, and choose a command that sounds related (e.g. if) then run if /? or help if.

@barlop, yes, I will remove the tempfile suggestion. "pipeline" is a UNIX term meaning a series of commands with pipes in the middle.
