Getting a "-bash: [: : integer expression expected" error on bash shell startup in arch

Anytime I startup my bash shell I'm getting this pervasive "-bash: [: : integer expression expected" error, which leads me to my .xinitrc, .bashrc, and .bash_profile. I just chaged my /etc/X11/xinit/xinitrc before this started happening, which leads me to believe it's related, but I'm stumped.

I was in the process of setting up xrdp, which might be a factor.

~/.xinitrc

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

if [ -f $sysresources ]; then







    xrdb -merge $sysresources

fi

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

if [ -f "$userresources" ]; then







    xrdb -merge "$userresources"

    xmodmap "$usermodmap"

if [ -d /etc/X11/xinit/xinitrc.d ] ; then

  [ -x "$f" ] && . "$f"
 done
 unset f

I've tried cleaning up my bashrc and bash_profile with no luck

Solution

  • Replace [ "${XDG_VTNR}" -eq 1 ] in your .bash_profile with [ "${XDG_VTNR}" = 1 ] so your .bash_profile looks like this:

    # ~/.bash_profile
#

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

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

    That should remove the error in the case that $XDG_VTNR is not set or not a number.

    For consistency in the usage of [ or [[ you may also want to change the line above, so your .bash_profile would look like this:

    # ~/.bash_profile
#

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

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

    But that's a matter of taste.
