Bash: delete phrase from string

Hello Community,
I have a string of words, "hello my name is batman", and i want to delete my name is from the string. I want to automate this process so that I can use it with other strings (ie. "hello my name is Robin"), but i don't want to be cutting characters because it is a different amount of characters for each one (it's obviously not as simple as "hello my name is..."). Thank you so much.

The OP wants to delete 'batman', or any name after "is ", so:
echo "hello my name is batman" | sed 's/$hello my name is $.*/\1/'
This will work on any name:
echo "hello my name is Robin" | sed 's/$hello my name is $.*/\1/'

Delete char from string

hi,
i have field like that 12-3456
and i wont to delete '-' to have 123456
what is the best way to do that?
Regards

Hi,
TRANSLATE field USING '- '.
CONDENSE field NO-GAPS.
The TRANSLATE command replaces al '-' with blanks and the CONDENSE, NO-GAPS compresses the string to remove all spaces/blanks.

Is it possible to save an iPhone back up and access the files later if needed? I have a string of text sms and iMessages that I would like to save and then delete them from my phone. Is this possible?

I have a string of text sms and iMessages that I would like to save and then delete them from my phone, but gain access to them later if I need them. I prefer to have the string with the date/time stamp vs copying and pasting into a doc or text file. Is this possible?

Not unless you buy an app that accesses data from an iTunes backup. Check in the app store.

Delete a char from string ?

Hi,
I want to delete a char from string. i used the following function.
String f = formulla.replace('[','');
The above function doesnt work as it tells me to put a space or some char in 2nd parameter which i dont want. i just want to delete all occurences of some specific char in a string.
Any suggestion.
Thanks alot.

u can do:
String before;
char charToReplace;
StringBuffer tempBuf = new StringBuffer(before);
for (int i=0; i<tempBuf.length(); i++)
if (tempBuf.charAt(i)==charToReplace)
tempBuf.deleteCharAt(i);
String after = tempBuf .toString(); HTH

Delete file from folder only (not from list)

Hi all,
I've searched a lot and didn't succeed so far, that's why I need your help. In a cloud context, I'm actually creating and uploading files (pdf and/or xml files) "on the go" to sharepoint folders via the SOAP API and this is perfectly working. But
in a cloud context, I also need to decomission services which is translated into deleting files into Sharepoint.
That's where it became complicated, because according to the API we cannot delete files if they are not part of a list structure, which is not my case. Is that true ?
The only info I have when trying to delete a file via the SOAP Api is : its name, its folder, and the endpoint where the folder is. So my question remains simple I guess : is this possible ? If so, how to (a link to the SOAP body would be usefull)
Thanks a lot
Regards
Baptiste

Hi,
According to your post, my understanding is that you want to delete file from folder.
In SharePoint 2010, It is recommended to use Client Object Model to achieve it, the following code snippet for your reference:
string siteURL = "http://siteurl";
ClientContext context = new ClientContext(siteURL);
//specific user
NetworkCredential credentials = new NetworkCredential("username", "password", "domain");
context.Credentials = credentials;
Web web = context.Web;
context.Load(web);
context.ExecuteQuery();
string relativeUrl =web.ServerRelativeUrl +"/DocumentLibraryName/FolderName/FileName";
File file = web.GetFileByServerRelativeUrl(relativeUrl);
context.Load(file);
file.DeleteObject();
context.ExecuteQuery();
If you still want to use SOAP API, we can use the UpdateListItems method under Lists web service to achieve it.

How to delete images from folder which are not in the database

I am created windows form
i wont to delete images from the folder where i have stored images but i only want to delete those images which are not in the data base.
i don't know how it is possible . i have written some code
private void button1_Click(object sender, EventArgs e)
string connectionString = "Data Source";
conn = new SqlConnection(connectionString);
DataTable dt = new DataTable();
cmd.Connection = conn;
cmd.CommandText = "select * from tbl_pro";
conn.Open();
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(dt);
int count = Convert.ToInt32( dt.Rows.Count);
string[] image1 = new string[count];
for (int i = 0; i < count; i++)
image1[i] = dt.Rows[i]["Image1"].ToString();
string[] image2 = new string[count];
for (int i = 0; i < count; i++)
image2[i] = dt.Rows[i]["Image2"].ToString();
var arr = image1.Union(image2).ToArray();
string[] arrays;
String dirPath = "G:\\Proj\\";
arrays = Directory.GetFiles(dirPath, "*", SearchOption.AllDirectories).Select(x => Path.GetFileName(x)).ToArray();
int b= arrays.Count();
for (int j = 1; j <= b; j++)
if (arrays[j].ToString() != arr[j].ToString())
var del = arrays[j].ToString();
else
foreach (var value in del) // ERROR DEL IS NOT IN THE CURRENT CONTEXT
string filePath = "G:\\Projects\\Images\\"+value;
File.Delete(filePath);
here error coming "DEL IS NOT IN THE CURRENT CONTEXT"
I have to change anything .Will It work alright?
pls help me

Hi Fresherss,
Your del is Local Variable, it can't be accessed out of the if statement. you need to declare it as global variable like below. And if you want to collect the string, you could use the List to collect, not a string. the string will be split to chars
one by one.
List<string> del=new List<string>();
for (int j = 1; j <= b; j++)
if (arrays[j].ToString() != arr[j].ToString())
del.Add(arrays[j].ToString());
else
foreach (var value in del)
string filePath = "G:\\Projects\\Images\\" + value;
File.Delete(filePath);
If you have any other concern regarding this issue, please feel free to let me know.

Deleting data from text files

Hi there,
I am having a real battle trying to delete data from a text file I am using. There seems to be this giant cloud with Java, where there is no real easy way to delete text from a file??
I have a JFrame with two textfields on it where you enter the username and pcname. There is a OK button once you have entered those details.
On action event I would like those two details, to be removed from the text file that has been read in.
I have a text file like this:
bob
pc1
bill
pc2
The data above gets written no problem, one at at a time using the below.
File f = new File("\\c:\\filename.txt");
String strToWrite;
try
FileOutputStream fstr = new FileOutputStream(f);
strToWrite = username1+ '\r'+'\n' ;
byte[] bytes = strToWrite.getBytes(); fstr.write(bytes);
strToWrite = pcname1 + '\r'+'\n' ;
byte[] bytes2 = strToWrite.getBytes(); fstr.write(bytes2);
strToWrite = username2+ '\r' +'\n' ;
byte[] bytes3 = strToWrite.getBytes(); fstr.write(bytes3);
strToWrite = pcname2 + '\r'+'\n' ;
byte[] bytes4 = strToWrite.getBytes(); fstr.write(bytes4);
catch (IOException e)
System.out.println("Error -- " + e.toString());
To read them back in I have made the follwoing:
BufferedReader br= null;
Count = 0;
try
br = new BufferedReader(new InputStreamReader(new FileInputStream("\\c:\\filename.txt")));
String s = "";
while((s=br.readLine()) != null )
Count = 1;
     //System.out.println("Data is " + s);
     inboundtext = s;
     if ( Count == 1 )
break;
while((s=br.readLine()) != null )
//System.out.println("Data is " + s);
inboundtext = s;
Count = 2;
if ( Count == 2 )
break;
catch(IOException ie)
finally
try
     if(br!=null) br.close();
catch(Exception e)
Now the above I know, is reading each line of the text file one at a time.
Now what I would like is that when the text that we got from the textfields, using getText(), be removed from the file without destroying the rest of the records in there? Why is it so easy to add and replace files, but not do any deleting from them?
please help!!

sorry, FileOutputStream fstr = new FileOutputStream(f);
should be FileOutputStream fstr = new FileOutputStream(f, true);

How do I delete text from a textArea?

How do I delete text from a textArea? I basically want the opposite of append(String)... I want something that removes a line from my TextArea. Anyone know?>

If you want to remove only a specific part of the text, you have to get the String, take the parts before and after the removed part, append them back together and use setText to replace it in the textArea.

How do I archive emails in mail and then delete them from my inbox?

I need to archive a bunch of emails for a project, and I know that if I put them in a mailbox and then delete them from my inbox, they're gone. So, what's the most efficient way to save 100s of emails that will eventually need to be filed within a project file?

// Sample code
List resList = new Vector();
MyObject obj = null;
while(rs.next()) {
obj.setXXX(rs.getXXX(i)); // Get from the resultset and set to the object
resList.add(obj);
// At the end of the loop, you have a Vector of objects holding data.What do you mean by returning Strings separately?

Attachments:

All that you need to do is right-click on the Read from Text File and Write to Text File functions and uncheck "Convert EOL".
Other comments:
You should not hard-code the path inside the VI. Either place a front panel control to specify the path (perhaps with a default value set), or generate the path so that it is relative to the VI (such as being in the same directory as the VI).
You are not wiring all your errors through so some errors can be lost.
You do not need to have the VI open a reference to itself. If you delete the Open VI Reference function the code will still work.

Hi,
You can check from v$session and see if any session is using the services using SERVICE_NAME in where clause. Below is the script for 3-node rac to check the service name and the number of sessions coming in using them
prompt Total Sessions by Service
select service_name "Service",
       count(*) "Total Sessions",
       sum(decode(se.inst_id,1,1,0)) "Inst 1",
       sum(decode(se.inst_id,2,1,0)) "Inst 2",
       sum(decode(se.inst_id,3,1,0)) "Inst 3"
from gv$session se
group by service_name
order by service_name;You can also check V$ACTIVE_SERVICES and V$active_session_history and also join then using SERVICE_HASH and NAME_HASH column.

Delete rows from table...Bizarre problem.

Folks
i HAVE this bizarre problem.
I hava a Java class which displays data read into a table with a delete
option by the side of each row.
Now lets assume you have 3 rows in the Table.
abc deleteButton
efg deleteButton
xyz deleteButton
When I click the first delete,that row gets deleted from the table.(perfect...)
Now I have 2 rows.
When I click on the first row,I get the error
'You clicked -1'
java.lang.ArrayIndexOutofBoundsException: -1 < 0.
Can anyone tell me why this is happening even though there are rows in the table.???
ActionListener al = new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("You clicked row : " + table.getSelectedRow());
javax.swing.table.TableModel model = table.getModel();
Object o = model.getValueAt(table.getSelectedRow(),0);
//System.out.print(model.getValueAt(table.getSelectedRow(), 0));
//System.out.println();
MyDeleteFunction(o.toString());
// Delete row from window.
((DefaultTableModel)table.getModel()).removeRow(table.getSelectedRow());
table.revalidate();
