Please check log & your .bashrc file in your $HOME
usually there is invalid line in .bashrc causes this problem.
e.g.
alias 'ls=ls --color'
test -s ~/.alias && . ~/.alias || true
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/lib
export PATH=$PATH:~//bin/vtstscripts/:/home/users/gx/tools/QE/qe-6.0/bin
export PATH=$PATH:~/jzq/script
export PYTHONPATH=~/phonopy-1.8.5.1/lib/python
tttt
Here the last line tttt is invalid, please delete this line.
Is this issue still present, gx? Should the new users also check this file?
if you don't experience the error, you dnt need to do anything
