__exim_lock__ is a program to lock a file in exactly the |
| |
|
22 |
same way as Exim would. It is intended for the investigation |
| |
|
23 |
of interlocking problems, but can also be used to prevent |
| |
|
24 |
Exim from modifying the file while you do something else to |
| |
|
25 |
it (for example if you need to manually edit your mailbox in |
| |
|
26 |
/var/mail). |
| |
|
27 |
|
| |
|
28 |
|
| |
|

Apart from specifying the name of the file to lock, which is |
| |
|
30 |
required, the following optional arguments may also be |
| |
|
31 |
supplied to __exim_lock__ : |
| |
|
32 |
|
| |
|
33 |
|
| |
|
34 |
__-v__ |
| |
|
35 |
|
| |
|
36 |
|
| |
|
37 |
specifies verbose mode (this is overridden if __-q__ is |
| |
|
38 |
also specified); |
| |
|
39 |
|
| |
|
40 |
|
| |
|
41 |
__-q__ |
| |
|
42 |
|
| |
|
43 |
|
| |
|
44 |
specifies quiet mode (takes precendence over __-v__ |
| |
|
45 |
); |
| |
|
46 |
|
| |
|
47 |
|
| |
|
48 |
__-fcntl__ |
| |
|
49 |
|
| |
|
50 |
|
| |
|
51 |
specifies that exim_lock should use an fcntl |
| |
|
52 |
lock; |
| |
|
53 |
|
| |
|
54 |
|
| |
|
55 |
__-lockfile__ |
| |
|
56 |
|
| |
|
57 |
|
| |
|
58 |
specifies that exim_lock should use a lock file (sometimes |
| |
|
59 |
called a |
| |
|
60 |
|
| |
|
61 |
|
| |
|
62 |
__-mbx__ |
| |
|
63 |
|
| |
|
64 |
|
| |
|
65 |
specifies that exim_lock should lock using MBX rules. To |

|

__command__ |
| |
|
71 |
|
| |
|
72 |
|
| |
|
73 |
specifies the command to run once the specified file is |
| |
|
74 |
locked. The mailbox will be unlocked again when this command |
| |
|
75 |
exits. |
| |
|
76 |
|
| |
|
77 |
|
| |
|
78 |
Note that if these parameters are not specified, then |
| |
|
79 |
__exim_lock__ will lock the file using fcntl and lockfile |
| |
|
80 |
methods, and then run a shell. |
