bash - Randomly create files and folders size of in 1M, 10M, 100M, 1G, 10G -


i have searched lot couldn't find solution this.

insida folder, how create random files , folders size of in 1m, 10m, 100m, 1g, 10g. each created folders needs have randomly created file in it.

you use dd different file sockets, e.g. /dev/random or /dev/zero.

this create 2mb file random data in it:

dd if=/dev/urandom of=file.out bs=1m count=2

or create 1mb file /dev/zero:

dd if=/dev/zero of=file.out bs=1024 count=0 seek=1024

there lot of examples out there, search "linux dd create file size". should wrapped in script create directories , files you. think of this.

#!/bin/bash #create files of 1, 10, 100 , 1000mb in size fsize in 1 10 100 1000 #create file size 1mb*fsize dd if=/dev/zero of=file.out bs=1024 count=0 seek=$((1024*fsize)) done

combined script create directories , fsize loop should want.

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. :)
