-ash: exprot: not found.

用 `ssh [email protected]`登录路由器后，出现:-ash: exprot: not found.

cat /etc/profile
#!/bin/sh
[ -f /etc/banner ] && cat /etc/banner
[ -e /tmp/.failsafe ] && cat /etc/banner.failsafe

export PATH=/usr/sbin:/usr/bin:/sbin:/bin:/mnt/material/opkg/usr/bin
exprot LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/material/opkg/usr/lib
export HOME=$(grep -e "^${USER:-root}:" /etc/passwd | cut -d ":" -f 6)
export HOME=${HOME:-/root}
export PS1='\u@\h:\w\$ '

[ -x /bin/more ] || alias more=less
[ -x /usr/bin/vim ] && alias vi=vim || alias vim=vi

[ -z "$KSH_VERSION" -o \! -s /etc/mkshrc ] || . /etc/mkshrc

[ -x /usr/bin/arp ] || arp() { cat /proc/net/arp; }
[ -x /usr/bin/ldd ] || ldd() { LD_TRACE_LOADED_OBJECTS=1 $*; }

请问，如何解决？我的openwrt出了什么问题？
