Hi,
I've got a shell script for installing a binary. In this script I set the
binary to mode 4755. When I 'ls' the binary from within the shell script I
see that it has the setuid bit set. When I exit the shell script, the binary
is no longer setuid.
I can setuid the binary from outside the shell script.
How can I setuid from within a shell script and have it stay that way?
e.g.
$ ./setuid_test_script.sh
mode of `/nfsroot/bin/busybox' changed to 4755 (rwsr-xr-x)
-rwsr-xr-x 1 root root 515956 2008-07-18 11:46 /nfsroot/bin/busybox
$ ls /nfsroot/bin/busybox
-rwxr-xr-x 1 root root 515956 2008-07-18 11:45 /nfsroot/bin/busybox
$ sudo chmod 4755 /nfsroot/bin/busybox
$ ls -al /nfsroot/bin/busybox
-rwsr-xr-x 1 root root 515956 2008-07-18 11:46 /nfsroot/bin/busybox
Impossible to say without more information. There's nothing in bash
itself that would cause it to remove the setuid bit from arbitrary
files created during a script's execution.
