Shell Script question

fractal

Right,

Lets say i have a shell script to insmod a list of modules..

so it might execute a command like:
insmod pcmcia_core

As well as whatever output of the shell script, insmod will give the output:

Linux Kernel Card Services VERSION
options: [pci] [cardbus]

Now lets say I dont want to see the insmod output.. I would have thought I could do something like this:

insmod pcmcia_core >/dev/null

But no... I still get the insmod splurge.. So I try:

insmod pcmcia_core >/dev/null 2>/dev/null

which seesm to do something.. but doenst stop the output of insmod getting to the console..

Could anyone tell me how to stop these insmod messages from displaying? I think the problem is coz insmod uses printk() to display the message and i dont know how to redirect the filestream.. But then I could be totally off the mark.

Any help appreciated

insmod 2&> /dev/null

at least if you are using bash...

Thanks, but...

Sorry should probably have mentioned, im using "ash"...

I know.. Strange choice but tis for a system based on busybox and uclibc..

Anyways long story short "insmod 2&>" doesnt work

But ash is pretty much POSIX-compliant, or so ive read, so there must be some way? (/me crosses fingers)

I must keep looking..

insmod module_name 2> /dev/null works for me in ash

For me,

It works if youre login terminal isnt /dev/console

ie: if you've sshed into the box it'll redirect the output off your ssh tty...

Still seems to get through to /dev/console though...

Or am i wrong? Try it for pcmcia_core module.. The insmod message (Using moduleName message) seems to be on STDOUT and can be redirected easily using > /dev/null

But the next bit ie: "Linux Card Services" doesnt go away..

BAH HUMBUG!

This is probably syslog then. If you want to disable this you can, just find what it's using in /etc/syslog.conf, but this maybe a bad idea. Could you say put them out to /dev/tty2 for example, so you have to hit control alt f2 to look at it.

Google for syslog+youros+console .

Typedef

insmod blah 2>&1 &

Strange..

Thanks everyone... All good suggestions.. Make sense.. Should be as easy as all that but it doesnt seem to be.

dmd: syslog wasnt running on this machine in question.. Reason being its an early stages distro in development. So it wasnt sending the messages to the wrong tty, coz it wasnt there..

Typedef: inmod blah 2>&1 &
This will send filestream 2 [thats stderr] to the same place as filestream 1 [stdout] and run the command in the background.

To be honest Im not sure its stderr i need to redirect as I _CAN_ alter where errors go with 2>/dev/null and where load messages go with >/dev/null..

I think theres a 3rd one im missing when certain modules load.. kernel msgs or somehting...

To be honest this isnt all that critical.. Tisjust to make the init routine look more purty on boot..

Thanks for suggestions so far anyways..

/me should probably sleep on it
