shell - find and grep command this but not that -

-

I am trying to find all the files that are *. O (object) files are not stored and stored in the MyFile.lst file in the current directory tree.

I am using this command. 

  #! / Usr / bin / ksh search-type F | Grep -v "* .o" & gt; & Gt;  
  Edit:   
  find-type F | Grep -v '\ .o $' & gt; & Gt; MyFile.lst   
 Looks like no comment / suggestions. (Added keith.layne correction)   
 
 
 You do not need  grep  .    Search Type 'F!' -name '* .o' & gt; & Gt; MyFile.lst   
 In GRP, search patterns should be a regular expression. Therefore, . ,  $  and  *  have special meaning.  
 . That means match any character, it means that the line X * means the match matches the end of X, zero or more times (greedy)   
  Grep -v '\ .o $ "  .o  will match the files with the extension. (You need to avoid the  for your code. ) .

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
