Yes that's exactly what I did and it didn't resolve the env. The output of `path("/a/b/c/$ENV{USER}")->absolute` for me is /a/b/c/$ENV{USER}. Using Perl 5.26.1. Edit: I misread. Sorry. Why did you replace /a/b/c/${USER} with /a/b/c/$ENV{USER}?	[reply] [d/l]

All worked here (FreeBSD 13, Perl 5.32, Path::Tiny 0.118) ... `# perl -Mstrict -Mwarnings -MPath::Tiny -E \ 'say join qq[\n], map path( $_ )->absolute(), q[~/tmp], q[~tester/tmp], qq[/tmp/$ENV{USER}] ' /home/parv/tmp /home/tester/tmp /tmp/parv` [download]	[reply] [d/l]

Perl is not bash, and has different interpolation syntax. If you want to interpolate the value of an environment variable into a string in Perl, you say `$ENV{USER}`, not `$USER`. As to why you got a literal `/a/b/c/$ENV{USER}`, are you sure you used `"/a/b/c/$ENV{USER}"` and not `'/a/b/c/$ENV{USER}'`? The single quotes do not interpolate.	[reply] [d/l] [select]

Very odd. Thinking to step ouside of Linux, I tested this on Windows. It appears to have worked correctly for me as well. `SKMDSK06::T:\>perl -V \| findstr uname uname='Win32 strawberry-perl 5.32.0.1 #1 Sun Aug 2 19:46:04 2020 +x64'` [download] `SKMDSK06::T:\>set user USERDOMAIN=SKMDSK06 USERDOMAIN_ROAMINGPROFILE=SKMDSK06 USERNAME=Steve USERPROFILE=C:\Users\Steve` [download] `SKMDSK06::T:\>type test01.pl use strict; use Path::Tiny; my $path = path("/a/b/c/$ENV{USER}")->absolute; print "$path\n";` [download] `SKMDSK06::T:\>perl test01.pl T:/a/b/c SKMDSK06::T:\>` [download] Not sure that this helps any, but there it is.

Because env vars are accessed using `$ENV{USER}`, and there presumably no var named `$USER` in your program. Seeking work! You can reach me at ikegami@adaelis.com	[reply] [d/l] [select]
