Appending a path in user's PATH variable
Hello Folks,
I want to append a path in user's PATH variable which should be available in current session.
Background
Numerous persons will run a utility.
Aim is to add the absolute path of the utility the first time it runs so that next runs have the PATH in env & users can directly run the utility without giving the absolute path.
Appended PATH should exist in the user's current session.
Where i got stuck
Shell scripts run as a separate process, hence, variables set there won't be accessible to parent shell.
We can use "." or "source" for the same.
These constructs are different for different shells.
Since the users are quite big chances of them running different shells is quite high.
This fails my run with . or source.
How to determine user's shell
echo $SHELL
This gives the developers shell. I changed my shell to different but the SHELL variable still gives the older shell value.
Hence, unable to determine the shell as well.
Please let me know how to achieve this.
Thanks in advance

NAME
systemd-path - List and query system and user paths
SYNOPSIS
systemd-path [OPTIONS...] [NAME...]
DESCRIPTION
systemd-path may be used to query system and user paths. The tool makes many of the paths described in file-hierarchy(7) available for

When invoked without arguments, a list of known paths and their current values is shown. When at least one argument is passed, the path
with this name is queried and its value shown. The variables whose name begins with "search-" do not refer to individual paths, but instead
to a list of colon-separated search paths, in their order of precedence.
OPTIONS
The following options are understood:
--suffix=
The printed paths are suffixed by the specified string.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
