在 arch 中的 bash shell 启动时出现“-bash: [: : integer expression Expected”错误

Question

每当我启动 bash shell 时，我都会收到这个普遍存在的“-bash: [: : integer expression Expected”错误，这会导致我进入 .xinitrc、.bashrc 和 .bash_profile。在这一切开始发生之前，我刚刚更改了我的 /etc/X11/xinit/xinitrc ，这让我相信它是相关的，但我被难住了。

我正在设置 xrdp，这可能是一个因素。

~/.xinitrc

#!/bin/sh

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap

# merge in defaults and keymaps

if [ -f $sysresources ]; then







    xrdb -merge $sysresources

fi

if [ -f $sysmodmap ]; then
    xmodmap $sysmodmap
fi

if [ -f "$userresources" ]; then







    xrdb -merge "$userresources"

fi

if [ -f "$usermodmap" ]; then
    xmodmap "$usermodmap"
fi

# start some nice programs

if [ -d /etc/X11/xinit/xinitrc.d ] ; then
 for f in /etc/X11/xinit/xinitrc.d/?*.sh ; do
  [ -x "$f" ] && . "$f"
 done
 unset f
fi

我尝试清理我的 bashrc 和 bash_profile，但没有成功

将

[ "${XDG_VTNR}" -eq 1 ]

中的

.bash_profile

替换为

[[ "${XDG_VTNR}" == 1 ]]

，这样你的

.bash_profile

看起来像这样：

# ~/.bash_profile
#

[[ -f ~/.bashrc ]] && . ~/.bashrc

if [ -z "${DISPLAY}" ] && [[ "${XDG_VTNR}" == 1 ]]; then
        exec startx
fi

这应该可以消除

$XDG_VTNR

未设置或不是数字的情况下的错误。
