Hide tce-load command output

[DesobedecoMinhaImaginacao]

A command that doesn't work:

tce-load -il compiletc &> /dev/null

[Rich]

Hi DesobedecoMinhaImaginacao
Does it work like this:

Code: [Select]

tce-load -il compiletc 2>&1 > /dev/null

[DesobedecoMinhaImaginacao]

It didn't work here.

Hi DesobedecoMinhaImaginacao
What didn't work? Your question sounds like you want
the command to be quiet. The command is quiet the
way it is written.

It the extension didn't load, you probably don't have it
downloaded:

Code: [Select]

tc@E310:~$ tce-load
Version 10.1
Usage: tce-load [ -i -w -wi -wo -wil -ic -wic -wicl]{s} extensions
  -i   Loads local extension
  -w   Download extension only
  -wi  Download and install extension
  -wo  Download and create an ondemand item
  Adding -c to any -i option will force a one time copy to file system
  Adding -l to any -i option indicates load only - do not update onboot or ondemand
  Adding -s to any option will suppress OK message used by apps GUI

Example usage:
 Load local extension:
   tce-load -i /mnt/hda1/tce/optional/nano.tcz
 Download into tce/optional directory, updates OnBoot and installs:
   tce-load -w -i nano.tcz
 Download only into tce/optional directory:
   tce-load -w nano.tcz
tc@E310:~$
Your command assumes the extension is downloaded.
If it isn't, try this:

Code: [Select]

tce-load -wil compiletc 2>&1 > /dev/null

[DesobedecoMinhaImaginacao]

The command below:

tce-load -il bc 2>&1 > /dev/null

Displays the installation output.  I really wish the command would be quiet.

TC 14.x x86_64

Hi DesobedecoMinhaImaginacao
Sorry, I can't reproduce your issue. I copied/pasted your
command on a  TC 14.x x86_64  system and it worked
perfectly.

... code]tc@E310:~$ tce-load

tc@E310:~$[/code] ...

See if it works like this for you:

Code: [Select]

tce-load -ils bc 2>&1 > /dev/null

The OK message has indeed been suppressed, but the loop-initiated message remains to be hidden

Hi DesobedecoMinhaImaginacao
I'm afraid I'm out of ideas. Base on the information you've
provided, I don't see why my example would not work.

Hi DesobedecoMinhaImaginacao
Are you running this on bare metal or virtual machine?

[curaga]

What loop initiated message? The kernel one, loop changed size to blahblah? That's not from the command, that's from the kernel, and you can hide it on the ttys by adjusting the kernel's log level (try the boot param "quiet").

[DesobedecoMinhaImaginacao]

Run on bare metal.

It remains to hide the message generated by the command on tce-load:

sudo mount /etc/sysconfig/tcedir/optional/bc.tcz /tmp/tcloop/bc -tsquashfs -o loop,ro 2>&1

IF memory serves, to hide kernel messages you can simply adjust "printk" levels.
Read the current levels (cat /proc/sys/kernel/printk) - let's assume they're 3 4 5 6 for this example.
Write the levels to 1 1 1 1, run your commands you want there to be no system messages, then re-write the levels back to where they started.
* Note: I don't remember if 1 1 1 1 is the lowest or 0 0 0 0

sudo dmesg -n [LEVEL] can also affect what you receive on the console
