Now it is able to replace all kind of statements (System.out.println) in *.java in the current directory only.
How can i make it work for all sub-directories as well?
Also it should display the list of all replaced files (with complete directory structure) for my further processing.
Assume, my directory structure looks like the following:
a
|
- I.java
- X.java
- b
|
- J.java
- Y.java
- c
|
- K.java
- Z.java
I am running the command from 'a' directory.

Please conside it for a file having more than 100 number of characters.

I just created a file in vi, looks like this:
Hello nobody
nobody
What I need is to have sed change the file so it looks like this:
Hello everybody
In other words, the sed query needs to look for both instances of "nobody" before it puts the word "everybody" on the first line. ... (2 Replies)
How do you print variables and your own words on the same line
ie in bash I would write something like
name="Calypso"
echo "your name is $Calypso"
how does awk differentiate between variables and just plain text
ie print "your name is name" ??
Thanks

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("*")'
