You are storing a literal asterisk in the LINE variable, and then, you're
expanding it without double quotes. One of the known side-effects of expanding
a parameter without guarding it with double quotes is that pathname expansion
occurs. Please, double quote "$LINE".


address@hidden:/$ v='*'; echo quoted: "$v"; echo unquoted: $v
quoted: *
unquoted: bin boot dev etc home initrd.img lib lib64 media mnt opt proc root run sbin srv sys tmp usr var vmlinuz
