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 : I need the Output of our command as:

stapex - systemtap examples
LANGUAGE BASICS
These examples give a feel for basic systemtap syntax and control structures.
global odds, evens
probe begin {
# "no" and "ne" are local integers
for (i=0; i<10; i++) {
if (i % 2) odds [no++] = i
else evens [ne++] = i
}
delete odds[2]
delete evens[3]
exit ()
}
probe end {
foreach (x+ in odds) {
printf ("odds[%d] = %d0, x, odds[x])
}
foreach (x in evens-) {
printf ("evens[%d] = %d0, x, evens[x])
}
}
This prints:
odds[1] = 1
odds[3] = 5
odds[4] = 7
odds[5] = 9
evens[5] = 8
evens[4] = 6
evens[2] = 2
evens[1] = 0
Note that all variables types are inferred, and that all locals and globals are automatically initialized.
This script prints the primes between 0 and 49.
function isprime (x) {
if (x < 2) return 0
for (i=2; i<x; i++) {
if (x % i == 0) return 0
if (i * i > x) break
}
return 1
}
probe begin {
for (i=0; i<50; i++)
if (isprime (i)) printf("%d0, i)
exit()
}
This script demonstrates recursive functions.
function fibonacci(i) {
if (i < 1) error ("bad number")
if (i == 1) return 1
if (i == 2) return 2
return fibonacci (i-1) + fibonacci (i-2)
}
probe begin {
printf ("11th fibonacci number: %d0, fibonacci(11))
exit ()
}
Any larger number may exceed the MAXACTION or MAXNESTING limits, and result in an error.
PROBING
To trace entry and exit from a function, use a pair of probes:
probe kernel.function("sys_mkdir") { println ("enter") }
probe kernel.function("sys_mkdir").return { println ("exit") }
To list the probeable functions in the kernel, use the listings mode.
% stap -l 'kernel.function("*")'
To list the probeable functions and local variables in the kernel, use another listings mode.
% stap -L 'kernel.function("*")'

The directory to find more examples can be found in the stappaths(7) manual page.
