I would like to change the file content which i specified like below.I want to comment out all the lines which contains ".class" except the class name i provide.
@MyClass1.MyClass2(value =
Class1.class,
Class2.class,
Class3.class,
Class4.class
)
public class Foo
For example if i provide Class2 as parameter to
sed -i -E 's/some_regex/Class2/g'
command,the result should be like this,
@MyClass1.MyClass2(value =
//Class1.class,
Class2.class,
//Class3.class,
//Class4.class
)
public class Foo
What regex should i use for this?
text-processing awk sed regular-expression

For a file like this:
$ cat file1
@MyClass1.MyClass2(value =
Class1.class,
Class2.class,
Class3.class,
Class4.class
)
public class Foo
@MyClass11.MyClass2(value =
Class1.class,
Class2.class,
Class3.class,
Class4.class
)
public class Foo2
You can have this result:
$ sed '/@MyClass1.MyClass2(*/,/})/s' file1
@MyClass1.MyClass2(value =
// Class1.class,
Class2.class,
// Class3.class,
// Class4.class
)
public class Foo
@MyClass11.MyClass2(value =
Class1.class,
Class2.class,
Class3.class,
Class4.class
)
public class Foo2
Explanation:
'/@MyClass1.MyClass2(*/,/})/ .... --> range to operate in form /from/,/to/actions
to avoid escaping //

Great answer,but i am just wondering, what if i want to apply // in all lines ending with .class? What regex should i use instead of {s|sClass.*|//&|g; ?

@aekber Maybe something likes|.class$|//&|g. The use of$is a regex anchor that means "end of line".

@aekber Maybe something like
s|.class$|//&|g. The use of $ is a regex anchor that means "end of line".– George Vasiliou
