@Stanley: Thanks for the help! Which version of cbq are you using? Mine is 0.7.3

this warning is an error in cbq script.

find: warning: you have specified the -maxdepth option after a non-option argument (, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it). Please specify options before other arguments.

open your /sbin/cbq ,and vi the file, modify it and looks like below:

577 ### Get a list of configured classes
578 CLASSLIST=`find $1 -maxdepth 1 $ -type f -or -type l\ ) -name ‘cbq-*’ \
579 -not -name ‘*~’ -printf “%f\n”| sort`
580 [ -z "$CLASSLIST" ] &&
581 cbq_failure “no configuration files found in $1!”
582
583 ### Gather all DEVICE fields from $1/cbq-*
584 DEVFIELDS=`find $1 -maxdepth 1 \( -type f -or -type l $ -name ‘cbq-*’ \
585 -not -name ‘*~’| xargs sed -n ’s/#.*//;
586 s/[[:space:]]//g; /^DEVICE=[^,]*,[^,]*(,[^,]*)?/ \
587 { s/.*=//; p; }’| sort -u`

Hi,

Thanks for your positive comment!
I have not used Suse for several years, so I don’t know if things are very different.
Did you get the cbq script from the iproute documentation just like my example in the post?
It might be a conflict between versions…

Hi,
very good and interesting article, thank you. I tried to do similar on SUSE 11.0, BUT I have neither of which did not work. Once enter the command cbq compile I get an error:

“#:/etc/sysconfig/cbq # cbq compile
find: warning: you have specified the -maxdepth option after a non-option argument (, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it). Please specify options before other arguments.
