• strange behaviour of grep in UNIX

  - by Happy Mittal

  When I type a command $ grep \\h junk then shell should interpret \\h as \h as two pairs of \ become \ each, and grep in turn, should interpret \h as \h as \ becomes \, so grep should search for a pattern \h in junk, which it is doing successfully. But it's not working for \\$. Please explain why ?

• How to attach files to an email in Windows Phone 7.5 Mango

  - by Vaibhav Garg

  In the default email client in Windows Phone 7.5 Mango, how can arbitrary files(.zip, .mp3, .txt, .pdf etc) be attached. As the storage is sand-boxed, the file handler can implement hooks to the email client, as MS-Office does and Adobe Reader doesn't, but the email client can not access files in the Phone's storage. Is there a way, or a work around? I my usage pattern, I tend to send a lot of pdfs, and am unable to do that!

  - by rajitha

  I have files with naming convention of this pattern: bond_7.LEU.CA.1.dat bond_7.LEU.CA.2.dat bond_7.LEU.CA.3.dat bond_12.ALA.CB.1.dat bond_12.ALA.CB.2.dat bond_12.ALA.CB.3.dat ...

• Websites on Ubuntu 8.04 LTS with Plesk are infected with viruses

  - by Paddington

  I am running Plesk 9.5 on Ubuntu 8.04 LTS and have about 15 websites infected with some malicious code appended to the end of java files. I have installed Clamav and it has managed to pickup the infected files which have a pattern of starting with either /*km0ae9gr6m*/ or /*gootkitstart*/ and ending with /*qhk6sa6g1c*/ or /*gootkitend*/ My Plesk panel is up to date and security patches were installed. How can I isolate the security vulnerability on the server?

  - by Chris

  I'm not experienced with IP tables but it's something I'll be looking into if this is plausible. I'm looking to set up a system to inspect packets and look for a pattern similar to korek's chop chop attack. Is there a way to set up the IP tables to defend against this attack? Thanks

• Exporting members of all DLs in an OU

  - by Bo Shubinsky

  I'm trying to export all the members of all the DLs within an OU (either to a single file that's categorized or individual files). I tried to use: csvde -f "C:\Documents and Settings\root\Desktop\AD Export\DL Export\DL.txt" -r "OU=DLs,OU=Personnel,DC=csi,DC=org" -l "cn,mail" but that only works for individual DLs and there are a lot to input each time. Any help on getting this done in the most efficient pattern would be helpful.

• grep not functioning correctly

  - by ak0

  I've been happily using grep for many years without any issues, but since today it quit working. During the past hour I tried this and that, but enough is enough, I'm posting the bastard here: On the simplest command like grep 'aaa' file.txt I'm getting this: grep: aaa: No such file or directory So grep does not interpret the first argument as the pattern as it should, but treats it as a path. Please help me, I'm going crazy '-(

• Annoying behavior from BitTorrent

  - by Click Upvote

  I'm trying to download a file via bittorent and experiencing a very annoying issue. Everytime I start downloading, the download rate varies between 40-50KB and stays at that for roughly a minute, before it starts to go down until it eventually gets as low as 2-3KB. If I exit and restart Bittorent it starts from 40-50KB again. What on earth is the reason for this? It seems like a pattern rather than the random fluctuation of seeds/peers leaving.

• Complex(?) regex: Is expression, but not another

  - by Kieron

  (If you can make a better title, please do) Hi, I need to make sure a string matches the following regex: ^[0-9a-zA-Z]{1}[0-9a-zA-Z\.\-_]*$ (Starts with a letter or number, then any number of letters, numbers, dots, dashes or underscores) But given that, I need to make sure it doesn't match a Guid, my Guid matching reg-ex looks like this (obviously, this needs to be negated in the merged result): ^([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}$ The last requirement here is that they must (if it's possible) be merged into a single expression.

  Is there any way to bulk-delete a bunch of objects matching a given query in LINQ or LINQ-to-Entities? The only references that I can find are outdated, and it seems silly to iterate over and manually delete all objects I wish to remove.

• Django QuerySet ordering by number of reverse ForeignKey matches

  - by msanders

  I have the following Django models: class Foo(models.Model): title = models.CharField(_(u'Title'), max_length=600) class Bar(models.Model): foo = models.ForeignKey(Foo) eg_id = models.PositiveIntegerField(_(u'Example ID'), default=0) I wish to return a list of Foo objects which have a reverse relationship with Bar objects that have a eg_id value contained in a list of values. So I have: id_list = [7, 8, 9, 10] qs = Foo.objects.filter(bar__eg_id__in=id_list) How do I order the matching Foo objects according to the number of related Bar objects which have an eg_id value in the id_list?
