Hello Sagar Singh,
I am having difficulty understanding what you are trying to do.

In post #1 you said you have thirteen files to search. In post #3 you said you have seven files and sort of showed us their contents. It seems that you are saying that each of your input files has a filename that is the string file followed by two octal or decimal digits, each file contains exactly one line of text, and if that line of text is not " Hello Sagar you want to print the filename and the contents of each file that does not contain that text and only that text with each output filename and contents separated from other filenames and their contents by an empty line of text.

But since none of your sample input files contain the leading <space> character that you say must be present, it would seem that the output should include every input file that you have shown us.

Have I understood your requirements correctly?

If you are not looking for a leading <space> character before "Hello Sagar" and just want a list of lines in file that do not contain the fixed string "Hello Sagar", then the command:

Code:

grep -Fv "Hello Sagar"

would give you a list of files that contain lines that do not match your pattern with the filename prepended to each line that does not match.

If you just want the filenames of files that do not contain your pattern, the code Ravinder suggested my be exactly what you want, but the grep -L option is an extension to the standards and will not be available on all systems. And, since you haven't told us what operating system you're using, we can't know if his suggestion will work in your environment.

If you really want the output to contain empty lines between the filenames and contents of each file that does not contain any line that matches your pattern, we could help you write a shell script that would do that, but we would need to know what shell you are using as well as what operating system you're using.

In your first post in this thread you said: "I want to send that file which has a diffrent string inside". Where do you want to send those files?

Please help us help you by providing details about the operating system you' are using, the shell you are using, more details about the format of the files you are processing, and an English description of the output you are trying to produce.

DtEditorChange(library call)											      DtEditorChange(library call)

NAME

       DtEditorChange -- change one or all occurrences of a string in a DtEditor widget

SYNOPSIS

       #include <Dt/Editor.h>
       Boolean DtEditorChange(
       Widget widget,
       DtEditorChangeValues *findChangeStrings,
       unsigned int instanceToChange);

DESCRIPTION

       The  DtEditorChange  function  replaces the next occurrence of a string, all occurrences of the string, or the currently selected text in a
       DtEditor widget with a replacement string.  The string to search for and the value to change it to can be the last values  entered  in  the
       Find/Change dialog (see DtEditorInvokeFindChangeDialog(3)) or passed as arguments to DtEditorChange.

       The search begins at the insertion cursor.  If the string is not found by the time the end of the document is reached, the search continues
       at the beginning of the document, stopping at the character before the insertion cursor.

       The widget argument specifies the DtEditor widget ID.

       The findChangeStrings argument specifies the string to change and the replacement value.  If findChangeStrings is NULL, DtEditorChange uses
       the  last  string  specified in the Find and Change To fields of the Find/Change dialog.  If the instanceToChange argument is DtEDITOR_CUR-
       RENT_SELECTION, the Find field of DtEditorChangeValues is ignored.

       If the instanceToChange argument is set to DtEDITOR_NEXT_OCCURRENCE, DtEditorChange replaces the next occurrence (relative to the insertion
       cursor)	of  the  find string.  If this argument is set to DtEDITOR_ALL_OCCURRENCES, all instances of the find string are changed.  If this
       argument ia set to DtEDITOR_CURRENT_SELECTION, the Find field of DtEditorChangeValues, is  ignored  and	the  currently	selected  text	is
       replaced.

       For a complete definition of the DtEditor widget and its associated resources, see DtEditor(3).

       For a complete definition of DtEditorChangeValues, see Dt/Editor.h - DtEditor(5).

RETURN VALUE

       Upon successful completion, the DtEditorChange function returns True if the substitution occurred; otherwise, it returns False.
