Hello all,
I would like to know if there is a generally accepted unix shell programming Guideline?
Do you have any idea where to find this?
There are a lot of programming Guidelines to find over Google, but is there one who is generally accepted? (3 Replies)

removable-media(9P) Kernel Properties for Drivers removable-media(9P)NAME
removable-media - removable media device property
DESCRIPTION
A device that supports removable media--such as CDROM, JAZZ, and ZIP drives--and that supports power management and expects automatic
mounting of the device via the volume manager should export the boolean (zero length) property removable-media. This property enables the
system to make the power state of the device dependent on the power state of the frame buffer and monitor. See the power.conf(4) discussion
of the device-dependency-property entry for more information.
Devices that behave like removable devices (such as PC ATA cards, where the controller and media both are removed at the same time) should
also export this property.
EXAMPLES
Example 1: removable-media Entry
An example of a removable-media entry from the .conf file of a driver is shown below.
# This entry keeps removable media from being powered down unless
# the console framebuffer and monitor are powered down
#
removable-media=1;
Example 2: Implementation in attach()
Below is an example of how the entry above would be implemented in the attach(9E) function of the driver.
xxattach(dev_info_t *dip, ddi_attach_cmd_t cmd)
{
...
if (ddi_prop_create(DDI_DEV_T_NONE, dip, DDI_PROP_CANSLEEP,
"removable-media", NULL, 0)) != DDI_PROP_SUCCESS)
goto failed;
...
}
