let me know anything else you need..

That file is mapped somewhere.. when i open it with an text editor it displays data..

but when i pull it it just upload blank.. so i pulled it other way..

that is odd, that it comes out blank. this is what it should end looking like

let see what I can figer out about this, I am getting this issue when booting this kernel and trying to find out what c010b22c ties to.

[c010b22c] *pgd=8021140e(bad)
Internal error: Oops: 80d [#1] PREEMPT SMP

this should work when in a rom

in terminal on the phone or through adb shell
$ su
$ # echo 1 > /proc/sys/kernel/kptr_restrict
$ # cat /proc/kallsyms &> /mnt/sdcard/kallsyms

now exit an its on your sd so..
$ # adb pull /mnt/sdcard/kallsyms

&> is correct, it states "and list output in"

it might work like that, but the & is not necessary. the > alone tells the output to go to the file listed after it.

might, might not, really dont know

I/O Redirection

but i know that the standard for redirecting output is just >

ampersand doesnt really mean and in that context
if you want something that actually means and in code its && as in

Code:

cat /proc/kallsyms && grep "c010b22c" > /mnt/sdcard/kallsyms

which has another inherent issue anyway... zte jellybean roms dont use mnt anymore they use storage, so youll wanna just do a simple redirect to /sdcard/kallsyms

SuperR · Jan 30, 2014

A single & actually sends the process to the background, and && waits for the first command to complete before moving on to the next. In junkie2100's example, it would actually be better to do

Code:

cat /proc/kallsyms | grep "c010b22c" > /mnt/sdcard/kallsyms

edit: Regardless of all that, after further reading 1mouse3's original command should work fine

actually, I pulled it via root explorer and zip it out, which is uploaded on start post.. . sorry for creating confusion....

once again,
