How could I exempt char to grep?

[packets]

Hi,

I have a lots of mailq in postfix. I want to create a script but the return of mailq is below:

83BE81A1872*
8797A1A1998*
8C45A1A1A72*
865D71A1A45*
845CC1A1A46*
86B7E1A1C09*

Is there a way in grep where I can remove the (*) so that I can delete the file manually?

grep is simply a matcher. You want an editor. Fortunately, in your particular case, Bash has this built in:

line="test*"
echo "${line%\*}"

${var%substring} notation means "Take the variable $var, and remove the shortest substring that matches my substring from the end".

In your particular case, just be careful with the '*', because this is a special character in Bash. Make sure you quote it.
