20250318在荣品的PRO-RK3566开发板的buildroot系统下使用ll命令【通过VI直接修改profile】
2025/3/18 10:40

缘起，在ubuntu20.04下使用ll命令习惯了。在Rockchip的Android10/11/12/13下也解决了ll命令的使用。
在Rockchip的buildroot下使用ll命令一直没有解决。

@余顺?请问如何在RK3566的buildroot下实现ll命令 ls -l
在 ubuntu下使用ll习惯了

这个在环境变量配置文件/etc/profile中间加上
alias ll='ls -al' 然后重启测试

在串口终端中使用VI直接修改/etc/profile：
root@rk3566-buildroot:/etc# 
root@rk3566-buildroot:/etc# diff profile profile.bak1 
--- profile
+++ profile.bak1

-
 export EDITOR='/bin/vi'
 
 # Source configuration files from /etc/profile.d
root@rk3566-buildroot:/etc# 
root@rk3566-buildroot:/etc# 

我直接使用了 ubuntu20.04的ll了。可以了

追问：我希望 直接将 ll编译进 IMG固件中。
请问该如何配置呢？

在sdk中find-name 同名文件将修改放进去去，然后重新清理之前构建的文件，重新编译buildroot 

./buildroot/system/skeleton/etc/profile
这个profile和板子上的profile很像。应该是这里了

root@rk3566-buildroot:/# cd /etc/
root@rk3566-buildroot:/etc#  
root@rk3566-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

alias ll='ls -alF'

export EDITOR='/bin/vi'

    if [ -r "$i" ]; then
        . $i
    fi
