Grep Gripes on FAT Fail. Busted or what?

and then it hangs. forever...

htop has it at 0 cpu... 0.2 mem so it doesn't bomb. just hangs ???

anyone ACTUALLY used the kindles grep - or am I making a new one - that works? Thanks

[qlob]

I have not used it, but I will go try it.
EDIT: It works for me, but I only tried it on a small file.

[twobob]

hmm...

find . -type f | xargs grep -l "/usr/bin/perl"

does stuff... er... confuzzled now.

Am I just being stupid?

ah well. I'll use that. thanks anyway

(xargs! - *shudder*)

[twobob]

[root@kindle bin]# find . -type f | xargs grep -l "/usr/bin/perl"
./intltool-extract
./intltool-merge
./intltool-update
./intltool-prepare
[root@kindle bin]#

Happy days.

[knc1]

Try:
strace -fF ....
Post the result.

The above just looks like it did not trace into the segfault message.

You will also notice that whatever is being traced, is built with multi-arch/multi-lib support (we don't really need that, there is only one K3 arch).

[NiLuJe]

@twobob: Perfectly normal. You need to ask grep to find something *somewhere*. Right now it's defaulting to reading stdin. Since there's nothing to match there, it hangs until something interesting happens in stdin .

EDIT: Hence why it works when you pipe something to it .

[twobob]

grep -l "/usr/bin/perl" *

DAAAAAAIIIIIEEEEE!!!!!!!! @__________@ DOH!

More tea!!!!

Thanks all. what a wally.

[knc1]

* * * * * *
Just practicing. Now if I could learn to read ...

[geekmaster]

Sadly, it takes me awhile to figure out why it is taking so long when I do that (but usually no more that 15 seconds or so).

[twobob]

I know, what a doof.

it was the first time I had run it on the device after installing 1.3 Gb of various software

I was a bit concerned I had blown it's mind. As it turns out it was my mind that needed looking at.

I can see the headlines now: "Human in brain fail shocker!"


BUSTED OR WHAT!!!

At least the replies you got were more helpful that a simple RTFM, or "grep --help". Can you imagine what would happen if a noob had that problem here?

[twobob]

It's true, note to self - do not poke noobs, poke, ouch! note to self - do not poke noobs, poke, ouch! note to self - do not poke noobs, poke, ouch! note to self - do not poke noobs, poke, ouch! note to self - do not poke noobs, poke, ouch!



EDIT: For some reason this remind me of an old Vic20 Program...

Poke 36529,blah. The color register if my befeebled mind still serves, Zomg, someone tell me why I can remember the poke registers for a 20 year old machine and can't remember how to use Grep.

Ah well. Back to finding errors in Perl. One file at a time. it's only been 6 hours no doubt my homebrew perl will soon be powerful enough to build yum. Better be I'm getting bored

If I have to run make microperl-reconfigure one more time I may go insane.
on the bright side it takes 1 min as opposed to 90 mins. Thank you Buildroot!

(Shameless "noob" (I still think I am one) plugging in here:

Isn't YUM written in python? Or am I just confused as to what microperl does?

EDIT: It's probably the latter as I just checked, and the wiki says it's written in Python.

For the record I burned 6 ish hours getting to that point.

I'll look at the Perl Makefile tomorrow.
MUST DO SOMETHING MORE EXCITING FOR A WHILE, serious boredom overload.

Samba it is : )
