'Failed to add mkshrc in Android Recovery

recovery:system/etc/mkshrc: trap '' INT /sbin/psh trap INT

That's all three lines,I don't know why I made that mistake: /system/etc/mkshrc[1]: trap: bad signal 'INT not foundsystem/etc/mkshrc[2]: /sbin/psh

If I just write this line(), no errors will be reported and PSH will work fine I'm a rookie. I'm sorry
