Suppose you invoke a script like this:
./script -abc -d13 -xyz file1 file2 file3
getopts will pull the options apart and deliver them to you one by one. So you will get a, b, c, d 13, x, y, and z.
Your script would use these options to set various internal flags and switches. Then it wants to get the rest of the parameters. This will be the file1, file2, file3.
This is where that shift comes in. That's how the scipt steps over the options to the rest of the parameters.
If there are no trailing parameters after the options, then yeah, no need for the shift.

Hi, i've got the following:
a=`echo $b | grep '^.*/'`
i'm storing in the variable the value of the variable b only if it has a / somewhere.
It works, but i don't want to print the value. How do i give the value of b to the grep command without the echo?
thanks! (5 Replies)
