ubuntu - Processing list of files and correctly naming the output files -


i'm using following command line on ubuntu try , work through list of tshark cap files , produce summary file separated. works fine. problem right @ end

sudo ls /capcopy/dump*.cap -l |awk '(nr>0) {print $9}'| xargs -i {} sudo tshark -n -r {} -t fields -e separator=$ -e quote=n -e header=n -e wlan.sa -e radiotap.dbm_antsignal -e  frame.time > /capcopy/dollarsep{}

the last element intended prepend characters dollarsep onto file name source. in same way in tshark element.

i can see doesn't work , creates file name dollarsep{}

is there way pass source file name forward can need?

thanks

change last command in pipeline to

xargs -i {} sudo bash -c 'tshark -n -r {} ... > /capcopy/dollarsep{}'

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
