LS Command – How to Set ls -l Time Format

The simplest way is to use the --printf option as suggested by @don_crissti:

stat --printf='%A %h %U %G %s %.16y %n\n' .bashrc

If, for whatever reason, you can't do that you can parse the output of `stat -c '%y':

$ stat -c'%A %h %U %G %s %y %n' .bashrc | awk '{$7=substr($7,1,8); $8=""}1;'
-rw-r--r-- 1 terdon terdon 9737 2015-02-01 18:12:18  .bashrc

Or you can use GNU date to convert it:

$ date -d "2015-02-01 18:12:18.665916181 +0200"
Sun Feb  1 19:52:18 EET 2015
$ date -d "2015-02-01 18:12:18.665916181 +020" +"%F %R:%S"
2015-02-01 19:52:18

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'
