Running a bash script from another bash script with different permissions

Question

I have a bash script archive.sh which belongs to User1 and has the permissions as 755. Also there are two other scripts archive1.sh and archive2.sh in the same directory, belonging to the same user (User1) but with permissions 744. The scripts archive1.sh and archive2.sh are called from inside the script archive.sh.

Now this script archive.sh is executed from another user User2 in the same group as User1. Since archive.sh has 755 permissions, it can be executed without any problem. But inside that script there are calls to archive1.sh and archive2.sh which have 744 permissions. So if I call archive.sh from User2, then will it execute the two scripts inside it?

When I tried it, the child scripts are running correctly but I am not sure how

I have tried it and the scripts are executing. But I am not sure why as they donot have the permissions. — user1004985, Jun 20 '12 at 08:19

Depends how the two "children" are called.

./child.sh will fail because you don't have the right permissions.

/bin/sh child.sh would work because you only need read access.

Is it "setuid" or something? Did a quick test and "./" didn't work. Which OS? – John3136 Jun 20 '12 at 10:43
Its Red Hat Enterprise Linux Server release 5.5 (Tikanga). Its not setuid. It has just some find and mv commands – user1004985 Jun 21 '12 at 08:14
