- Where Developers Learn, Share, & Build Careers


I am currently in the process of modifying a large BASH script which installs / checks a series of packages in a few different Districts. (Mainly Redhat and Debian based).

To handle some differences between distros (such as RPM versus DPKG, Wiim Vs, APT, etc.), I am trying to load some variables with different command strings so that the script is filled with If it is Debian, otherwise this statements, though it appears that it does not like to put awk inside an eval statement, and I do not know why it may be.

Example

# Examples DPKG - List Product # ii bash 4.1-2ubuntu3 GNU Born Again DPKG - List | Grep 'bash' # Output Bidding Entries in DPKG CMD = "DPKG - Listing | GRP 'Beash'" EVALE $ CMD # Production as expected, DPKG-list as above. Awk '/^.i/ {print $ 2}' # Output as expected, a list of package names Cmd = "dpkg --list | awk '/^.i/ {print $ 2}' 'eval $ cmd # Print out the full output from DPKG for each line that matches the regx.

In the code above, just looks fine for a given package, and prints as expected. , But when trying to prepare a complete list of package names using awk, then print $ 2 is ignored And just prints the whole line.

Any ideas?

This is the reason: 

  cmd = "dpkg --list | Awk '/^.i/ {print $ 2}' 'echo $ cmd output: dpkg --list | $ Sign escape:  
  cmd = "dpkg --list | awk" / ^. I / {print \ $ 2} '"

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
