Programming :: Awk Computed Regex Not Working As Expected

May 31, 2011

So those of you that know me will agree that when it comes to awk I don't usually ask a lot of questions ... however this one has me stumped. I am guessing I have missed something obvious but for the life of me (and I have tested at great length) I cannot find it So the scenario is this: The following awk code should identify all versions of libgpg-error within the attached file (see below) and only show one for each version:

Programming :: ! For Not Matching Bash Regex?

Jan 13, 2011

In a bash-script, only the case if a regular expression does not match is relevant.herefore I used the exclamation mark !. But where to place it?

These two work fine, but are they equivalent?
Code: if ! [[ $abc =~ $pattern ]]; then or
Code: if [[ ! $abc =~ $pattern ]]; then Where is the ! placed more correct?

Programming :: Find With A Regex Path?

May 5, 2010

I'm using bash scripting to find any file that matches a path governed by the following regular expression:

"(monthly|nightly).[0-9]+/home/(user1|user2)/.mailbox/"
to match files like:
monthly.9/home/user1/.mailbox/l23131564
nightly.15/home/user2/.mailbox/cur/6546213

I've tried:

Code:
myRegex="(monthly|nightly).[0-9]+/home/(user1|user2)/.mailbox/"
find ./ -regextype posix-egrep -regex $myRegex

and it just spins and never gives me an answer, even though the file structure isn't that big.

OpenSUSE :: Use Of Setfacl Not Working As Expected

Jun 4, 2010

I used setfacl to set permissions as follows:

As you can see all settings lead to permissions 777 but that's not what happens. What happens if I say, touch a file, I get: 666 as this shows:

Same for files that are not obviously scripts such as just a.txt.

My umask is 0022.

Does anyone know why this is? Is it changeable for specific directories?

This is a special world viewed directory required by a piece of software... in other words, no, I am not in a habit of setting file permissions to 777 so please no comments about you shouldn't be using such permissions.

Truthfully, I can probably get away with permissions 666 and will if I can but right now I just want to know why it's happening this way and how to control it.

Red Hat / Fedora :: DST Change Over Not Working As Expected

Mar 24, 2010

I'm trying to test whether some software that I am using will behave as expected when DST change over occurs. I'm specifically testing it for the GB timezone when it enters British Summer Time (BST) and then reverts to GMT. From the information I have, BST starts: Sunday 28 March 01:00 GMT (02:00 BST)and ends: Sunday 31 October 02:00 BST (01:00 GMT )To do this test I wrote a shell script that sets the date, runs the program, checks some logs and then reverts the time.

Entering BST was fairly straight forward as all I had to do was the following: export TZ=GB
date 032800582010This set the date to be 28th March and the time to be 00:58 in the GB (GMT) timezone. As expected, the date then rolled forward to 02:00 BST. However, when I tried to do the same for coming out of BST into GMT, the time did not work out as expected. export TZ=GB
date 103101582010Setting the time as above put the time straight into GMT and not BST even though it was two minutes before the time should have rolled-over.

However if I put the following: export TZ=GB
date 103100582010the date was reported as BST!
How can I setup the time so that I don't have to wait for hour before BST ends?

Programming :: Specific Regex Pattern In Perl?

Feb 23, 2011

I'm fairly new to Perl and regular expressions. I have a large collection of files with their file names in the following general format: string - another string with spaces (2004) [year].ext I would like to know how I could create a regex to separate out:

the first string
another string with spaces
year
extension

If you know of a better way of doing it without regular expressions, I would be happy to hear that way too.

General :: Locale Adjustment Not Working As Expected?

May 13, 2011

On Slackware64 13.1 the as-installed en_GB locale gave Sunday as the first day of the week. This was not an issue until Xfce's Orage calendar was used when its display of Sunday as the first day of the week was offputting for someone used to Monday. A minor inconvenience but expected to be easy to fix.

At the command line:

There is this one server running CentOS5.4 Final which has certain application like Bugzilla. I have setup ssh on it and setup is for password less authentication.

Though password less authentication is working fine, but I am also able to login using password.

Code:

RSAAuthentication yes

CentOS 5 Server :: Openldap Acl Not Working As Expected?

Jun 22, 2009

CentOS 5.2. Openldap server-2.3.27-8.el5_2.4 I'm trying to get the server to do two things. One is allow authentication--that is, if a client is configured to use openldap for authentication, it should be able to access this server.

In other words, on machine_2, a client, doing getent passwd (as a quick test) will show the users in the openldap database. The more or less out of the box configuration works for this. However, as soon as I start trying to add ACLs, it stops working. For example, I want to restrict access to an address book which is also in the database. So I have

access to base.dn(changing base to subtree makes no difference) "ou=addressbook,dc=example, dc=com"
by users read by anonymous auth Now, even though this is just the address book, after that, an ldap client can no longer get the names of users in ou=People, and using the ldap server for authentication doesn't work.

I don't understand what I'm missing. ACLs are supposed to work first match wins. *IF* I add under that, access to * by * read, it will work, but the address book can then be accessed without a bind dn.

I am not sure what I'm overlooking. If I put in any sort of access control, the only way that clients can continue to use the server for authentication is adding that access to * (or to dc=example,dc=com"), by * read. I tried using access to ou=Group and ou=Peoplle by * read, thinking that would allow the clients to authenticate, but that doesn't work either, The idea is to allow any machine configured as a client to use it for authentication, but also to restrict viewing the address book only to those with a proper bind dn name.

Apr 8, 2011

I want to match for this string:

Content-Disposition:[:space:]attachment;[:space:]filename="%variable%"

Both lines are new lines, so they won't be inline. Other than that, they are all constants, I want this regex match to be an if statement rather than returning match string. so if the $content variable contains some string that matches:

Code:

How do I match for multiple strings in the $contents and return them as an array? for example

Code:

the sed func would be able to recognize both "text"s, but only one is outputted?

Possible to put it in an array? so ${bar[0]} gives one and ${bar[1]} gives another

Ubuntu Servers :: Postfix+dovecot Not Working As Expected?

Nov 9, 2010

I have tried to find solution in existing posts but could not specifically find any with my kind of issues and hence a new post on oft repeated subject !! -- and apologies for a long long post here.Here is where I am ..On a AMD 64bit machine - I have ubuntu 10.10 desktop installed. I want this development machine to support virtual mailboxes so that I can use them from multiple apps and create real life deployment situations.I installed postfix + dovecot following the tutorials available here and current state is - I can send mails using telnet sessions and I see that the mail files are getting created in /Maildir form as I have directed in the conf files. I have configured Thunderbird mail client as well.

Issue #1: Mail sending works from Thunderbird but it always responds back with 'No mail on server' message when I try to receive mails. SMTP is configured with STARTTLS and POP3 with None (i.e. plain text password)Issue #2: Also, while going thru conf, logs and during testing - I found a few things which defer in this installation for authentication. I have given the session transcripts here.Issue #3: That being major issue - I also want to configure my virtual users to use TB client to access their mails - I did not find any tutorials or pointers towards that in my search for past few days. If I send mails to a non-Unix virtual user - the mail gets stored into /home/vmail/<domain>/<user>/new directory.Here are the conf files.main.cf for postfix

Code:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first

General :: Bulk File Rename Not Working As Expected?

Well, I thought that should have work but the problem is that $source comes up broken, when I run it with echo instead of mv I get the echo with broken names.

In this case "$source"="This is the file I want to rename"
$ echo "$source"
