Question How to extract the value of "%" using scripting?
Hi Gurus,

I'm using HPUX system (unix based system).

When I execute "bdf" command, it will display the following information (sample data only):

Code:
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol4 2097152 1623080 470400 78% /tmp
/dev/vgsap/oracle 262144 6299 239910 3% /oracle
...<blank space>...10485760 4859180 5274921 48% /oracle/stage/102_64
...<blank space>...262144 117369 135731 46% /oracle/client

My question is, how would I be able to extract the percentage value out?

Desired output:
Code:
78%
3%
48%
46%

Please take note that somehow there is an empty space at the front in the last 2 lines. Space is represented as <blank space> as shown above.

Would appreciate for any of your help and advice.

Thank you.



Regards,
Peter

Hi All,

Thank you for all of your responses and advices.

With your help, I've managed to extract out the percentage.

Here is my current output format.
Code:
/tmp 78% 
/oracle 3% 
/oracle/stage/102_64 48% 
/oracle/client 46%

However, how would I be to format the output into this below format?

Code:
/tmp............................78% 
/oracle.........................3% 
/oracle/stage/102_64.....48% 
/oracle/client................46%

Once again, thanks for your help.

PS:
Please ignore the dotting (..............) as it's used for format alignment only.


Regards,
Peter

Try:
Code:
bdf|awk 'NR>1{printf "%28-s%3s\n",$NF,$(NF-1)}'

Hi,

Thank you for your response.

I've tried your command, but it does not work as sometimes the path can be quite long and it's carried to the next line.

Here is the output:

Code:
bdf|awk 'NR>1{printf "%28-s%3s\n",$NF,$(NF-1)}'
/dev/vgsap/orastage         /dev/vgsap/orastage
/oracle/stage/102_64        48%
/dev/vgsap/oraclient        /dev/vgsap/oraclient
/oracle/client              46%

Please kindly advice.

Thanks.


Regards,
Peter

How about:
Code:
bdf | awk 'NR>1&&NF>1{printf "%32-s%3s\n",$NF,$(NF-1)}'
