Question

When I read[command] some lines including character '*', it seems that '*' will be looked as a wildcard. whether exsits some solutions leting '*' just be a '*', please!

Answer 1

If you do not want any of the special file name characters to be used as wildcards then enter the following in your script before the read.

set -o noglob

This will prevent the * ? and [] from having special meaning and treat them as normal characters.

The following example demonstrates the point

touch 1 2 3
echo "With wild card expansion"
echo *

echo "Without wild card expansion"
set -o noglob
echo *

And produces the following results

With wild card expansion
1 2 3 
Without wild card expansion
*
