我的 $PATH 与 /etc/profile 中所述的不同

这是我的整个 /etc/profile。

# /etc/profile: system-wide .profile file for the Bourne shell (sh(1))
# and Bourne compatible shells (bash(1), ksh(1), ash(1), ...).

if [ "$(id -u)" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH

if [ "${PS1-}" ]; then
  if [ "${BASH-}" ] && [ "$BASH" != "/bin/sh" ]; then
    # The file bash.bashrc already sets the default PS1.
    # PS1='\h:\w\$ '
    if [ -f /etc/bash.bashrc ]; then
      . /etc/bash.bashrc
    fi
  else
    if [ "$(id -u)" -eq 0 ]; then
      PS1='# '
    else
      PS1='$ '
    fi
  fi
fi

if [ -d /etc/profile.d ]; then
  for i in /etc/profile.d/*.sh; do
    if [ -r $i ]; then
      . $i
    fi
  done
  unset i
fi

根据文件,我的$PATH应该是/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/binroot,/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games如果不是。然而,我的实际情况$PATH有所不同。

daniel@debian:~$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/snap/bin

root@debian:/# echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/snap/bin

My$PATH固定为/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/snap/bin不考虑权限,与 中写入的不同/etc/profile。为什么会出现差异?我该如何纠正这个问题?

路径线

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

仅对 UID 0(即 root)有效。
