Re: TeXLive and dist-upgrades of Debian Stable

After reading through inputs from different personalities, I, hereby, am posting what I tried.

This is my ~/.bashrc

I've added the following at the end.
export PATH=/usr/local/texlive/2025/bin/x86_64-linux:$PATH
export MANPATH=/usr/local/texlive/2025/texmf-dist/doc/man:$MANPATH
export INFOPATH=/usr/local/texlive/2025/texmf-dist/doc/info:$INFOPATH

Did a logout and a restart even. But no luck.

The following is the result of echo $PATH :

/usr/local/texlive/2025/bin/x86_64-linux:/home/vrgovinda/bin:/home/vrgovinda/.local/bin:/usr/local/texlive/2025/bin/x86_64-linux:/home/vrgovinda/.local/bin:/home/vrgovinda/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

Other files I have in my /home are: .bash_logout and .bash_history.
I guess these have nothing to do with what we are discussing about.

And about what gets read when, I got this info from ~/.bashrc and ~/.profile

# ~/.bashrc: executed by bash(1) for non-login shells.

# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.

I have neither ~/.bash_profile nor ~/.bash_login.

To repeat my original queries:
1. How to update TL 2025.
2. had queried about ~/texmf (got the answer.)
3. How to switch between my old TeXLive and this one.
