i have a Java project with more than 5000 java/jsp files.
In about all the java/jsp files there is System.out.println.
I need to comment all the //System.out.println line from all the java files.
But need to see which are all the files before commenting. --> This [commenting] I will do later
Now my need is to list all the java files containing system.out.println:
and the output i need is :
Code:
/home/me/project/file1.java [system.out.println containing file name]
somejavacode [second line before system.out.println]
somejavacode [first line before system.out.println]
System.out.println("something");
somejavacode [first line after system.out.println]
somejavacode [second line after system.out.println]
somejavacode [third line after system.out.println]
/home/me/project/file156.java [system.out.println containing file name]
somejavacode [second line before system.out.println]
somejavacode [first line before system.out.println]
System.out.println("something");
somejavacode [first line after system.out.println]
somejavacode [second line after system.out.println]
somejavacode [third line after system.out.println]
/home/me/project/file871.java [system.out.println containing file name]
somejavacode [second line before system.out.println]
somejavacode [first line before system.out.println]
System.out.println("something");
somejavacode [first line after system.out.println]
somejavacode [second line after system.out.println]
somejavacode [third line after system.out.println]
etc..
Code:
Here is an Example java file convertBoolean.java
/*
Convert java Boolean object to String object Example
This example shows how to convert java Boolean object into String object.
*/
public class JavaBooleanToStringExample {
public static void main(String[] args) {
//construct Boolean object
Boolean blnObj = new Boolean("true");
//use toString method of Boolean class to convert it into String
String str = blnObj.toString();
System.out.println(str);
}
}
I need the Output of our command as:
Code:
..
..
..
/home/me/project/convertBoolean.java
//use toString method of Boolean class to convert it into String
String str = blnObj.toString();
System.out.println(str);
}
}

look
LOOK(1) BSD General Commands Manual LOOK(1)NAME
look -- display lines beginning with a given string
SYNOPSIS
look [-bdf] [-t termchar] string [file ...]
DESCRIPTION
The look utility displays any lines in file which contain string as a prefix.
If file is not specified, the file /usr/share/dict/words is used, only alphanumeric characters are compared and the case of alphabetic char-
acters is ignored.
The following options are available:
-b Use a binary search on the given word list. If you are ignoring case with -f or ignoring non-alphanumeric characters with -d, the
file must be sorted in the same way. Please note that these options are the default if no filename is given. See sort(1) for more
information on sorting files.
-d Dictionary character set and order, i.e., only alphanumeric characters are compared.
-f Ignore the case of alphabetic characters.
-t Specify a string termination character, i.e., only the characters in string up to and including the first occurrence of termchar are
compared.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of the look utility. Their effect is described in environ(7).
FILES
/usr/share/dict/words the dictionary
EXIT STATUS
The look utility exits 0 if one or more lines were found and displayed, 1 if no lines were found, and >1 if an error occurred.
COMPATIBILITY
The original manual page stated that tabs and blank characters participated in comparisons when the -d option was specified. This was incor-
rect and the current man page matches the historic implementation.
look uses a linear search by default instead of a binary search, which is what most other implementations use by default.
SEE ALSO grep(1), sort(1)HISTORY
A look utility appeared in Version 7 AT&T UNIX.
BUGS
Lines are not compared according to the current locale's collating order. Input files must be sorted with LC_COLLATE set to 'C'.
