Need command to convert Hexadecimal kernal parameter value

[ezhilarasan_1]

Hi,

Need command or script to convert Hexadecimal kernal parameter value to Decimal value.
In some servers, kernal parameter values are being set in Hexadecimal. I want to see actual decimal value for semaphores and shared memory parameters setting.

Please help for this.

Thanks
Ezhil

To convert hex to decimal:

# printf "%#d" 0xfda456

Where 0xfda456 is your hex number.

To convert decimal to hex:

# printf "%#x" 12345
or
# printf "%#X" 12345

The only differrence in the above 2 commands is that the first will use lowercase characters and the 2nd will use upper case characters.

Do it as follows.

printf "%d\n" 0x"hex_value"

echo "0Xhex_value=D" | adb

You can use adb.

To convert hex 7F to decimal type:

echo '0x7f=D' | adb

You will receive the following output:

127

and To convert decimal 127 to hex type:

echo '0d127=X' | adb

You will receive the following output:

7F

I posted kmtune.pl in http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=65781

That would not only convert dec to hex and back but also gives you filtering

If you are using SAM, it always decode the hex (and formula) values to decimal just below the setting line. There is no need to leave any parameter in hex--just type the desired decimal value. The reason some values have a default in hex is lost in antiquity...just use decimal to overwrite the hex value.

Yes, I agree with Bill herein, you can change this using sam via x-windows version.
