20260420给万象奥科的开发板HD-RK3576-PI适配瑞芯微原厂的Buildroot时使用ll命令
2026/4/20 20:52

1、根据经验，ll需要在profile文件中配置：
rootroot@rootroot-HP-245-14-inch-G10-Notebook-PC:~/git_RK3576_Linux6.1$ 
rootroot@rootroot-HP-245-14-inch-G10-Notebook-PC:~/git_RK3576_Linux6.1$ 
rootroot@rootroot-HP-245-14-inch-G10-Notebook-PC:~/git_RK3576_Linux6.1$ find . -name profile

2、实测ll的效果：
root@rk3576-buildroot:/# 
root@rk3576-buildroot:/# ll
total 76

root@rk3576-buildroot:/# 

3、确认profile中修改的效果：
root@rk3576-buildroot:/etc# 
root@rk3576-buildroot:/etc# cat profile
export PATH="/usr/bin:/usr/sbin"

if [ "$PS1" ]; then
  if [ "$BASH" ]; then
    # The file bash.bashrc already sets the default PS1.
    # PS1='\h:\w\$ '
    if [ -f /etc/bash.bashrc ]; then
      . /etc/bash.bashrc
    fi
  else
    if [ "`id -u`" -eq 0 ]; then
      PS1='# '
    else
      PS1='$ '
    fi
  fi
fi

export EDITOR='/bin/vi'

# Source configuration files from /etc/profile.d
for i in /etc/profile.d/*.sh ; do
    if [ -r "$i" ]; then
        . $i
    fi
done
unset i

# 2026/4/20 19:33
# some more ls aliases
alias ll='ls -alF'
alias la='ls -A'
alias l='ls -CF'

root@rk3576-buildroot:/etc#
