O que causou o problema versus como resolvê-lo são duas coisas diferentes. O que eu sei isso é o conteúdo de um arquivo Bash .bash_profile
razoavelmente padronizado; via RedHat 7:
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/.local/bin:$HOME/bin
export PATH
E esses são os conteúdos de um arquivo Bash .bashrc
razoavelmente padronizado; via RedHat 7:
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=
# User specific aliases and functions
Além disso, o conteúdo de /etc/bashrc
no RedHat 7 é o seguinte:
# /etc/bashrc
# System wide functions and aliases
# Environment stuff goes in /etc/profile
# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.
# are we an interactive shell?

Observe também que você só deve editar arquivos como este com um editor de texto puro. Se você usar um processador de texto ou algo “mais sofisticado” do que isso, acréscimos extras e “gremlins” podem ser adicionados ao seu arquivo, o que deixaria o sistema entupido.
