How to set ls -lh with time and long date format in descending order in .bashrc

You are missing a -l to turn on the long listing format and -t to sort by modification time.

Do:

alias ll='ls -lt --color=auto --time-style=long-iso'

To include hidden files too:

alias ll='ls -alt --color=auto --time-style=long-iso'

To reverse the order of sorting, oldest first, add -r:

alias ll='ls -ltr --color=auto --time-style=long-iso'
alias ll='ls -altr --color=auto --time-style=long-iso'
