Shell Programming and Scripting

@Klashxx line modified for the OP requested output:

Code:

awk 'BEGIN{FS="X0";RS=" "} NF!=1{print NF-1}' filename

Thanks All for your help...

But all code which you posted does not work as what I expected. Please, see my desired output below.

I try to explain again more clearly..

If an X or consecutive Xs followed by 0 is count as occurrence 1
e.g: X0 , XX0, XXX0, XXXX0, ... count as occurrence 1



Here is my Input Data:
1 0
2 0
3 0
4 X
5 0
6 X
7 0
8 0
9 0
10 0
11 X
12 0
13 X
14 X
15 0
16 X
17 X
18 X
19 0
20 X
21 X
22 0
23 0
24 0
25 0
26 X
27 X
28 X
29 X
30 X
31 0
32 0
33 0

If it arrange in Line:
000X0X0000X0XX0XXX0XX0000XXXXX000





Then, we can distinguishes as follow:
000 X0X0 000 X0XX0XXX0XX0 0000 XXXXX0 00

X0X0 = count as occurrence 2(there are two X0s)
( X0-X0 = 2 Occurrences )


X0XX0XXX0XX0 = count as occurrence 4

( X0-XX0-XXX0-XX0 = 4 Occurances )

XXXXX0 = count as occurrence 1

So, My Desired Output is:
2
4
1


I hope you can understand my explanation

Have you tried my solution?

Code:

$ cat file
000 X0X0 000 X0XX0XXX0XX0 0000 XXXXX0 00
000 X0X0 0X0 X0XX0XXX0XX0 0000 XXXXX0 00
00X X0X0 000 X0XX0XXX0XX0 X000 XXXXX0 00
$
$
awk '{
  print "Line : " NR
  for(i=1;i<=NF;i++){
    n=gsub("X0","",$i)
    if(n){print n}
  }
}' file
Line : 1
2
4
1
Line : 2
2
1
4
1
Line : 3
2
4
1
1

If you don't want to output the line numbers remove the first print command.

Thanks Franklin52,

Yes, I have tried your solution but the code did not work what I expected.


$ cat file
000 X0X0 000 X0XX0XXX0XX0 0000 XXXXX0 00
000 X0X0 0X0 X0XX0XXX0XX0 0000 XXXXX0 00
00X X0X0 000 X0XX0XXX0XX0 X000 XXXXX0 00

If I used your file input (above), my desired output should be as follow:
Line : 1
2
4
1
Line : 2
2
5
1
Line : 3
2
5
1


Explanations:


Line 1 is OK !



Line 2:

Line: 2 should be arranged: 000 X0X0 0 X0X0XX0XXX0XX0 0000 XXXXX0 00
X0X0 = X0, X0 = 2 Occurrences
X0X0XX0XXX0XX0 = X0, X0, XX0, XXX0, XX0 = 5 Occurrences
XXXXX0 = 1 Occurrence
Output of Line 2 should be:

2
5
1




Line 3:

Line: 3 should be arranged: 00 XX0X0 000 X0XX0XXX0XX0X0 00 XXXXX0 00
XX0X0= XX0, X0 = 2 Occurrences
X0XX0XXX0XX0X0= X0, XX0, XXX0, XX0, X0 = 5 Occurances
XXXXX0 = 1 Occurances
Output of Line 3 should be:
2
5
1




I hope you can catch what I want....


Thanks

You arrange the 3th field from the second position to the 4th field at line 2 and the 5th field to the 4th field at line 3. Sorry I don't understand the logic.

Maybe it should be helpful if you post your original file and the desired output of that file.

Regards

Thanks Franklin52,

Ok, I think, distinguishes by field confuse us. (Actually, we dont need to distinguishes by field, this distinguishes is only separate the consecutive occurrence and non occurrences)

If we take the your input file again:
Line 2:
000X0X00X0X0XX0XXX0XX00000XXXXX000
then:
000X0X00X0X0XX0XXX0XX00000XXXXX000
2 5 1

Line 3:
00XX0X0000X0XX0XXX0XX0X000XXXXX000
then:
00XX0X0000X0XX0XXX0XX0X000XXXXX000
2 5 1

Again, If an X or consecutive Xs followed by 0 is count as occurrence 1
e.g: X0 , XX0, XXX0, XXXX0, … count as occurrence 1

Please, look the pattern carefully:

0000X0X0X000 = 3 Consecutive Occurrences (X0, X0, X0)
3

000XX0X0X000 = 3 Consecutive Occurrences (XX0, X0, X0 )
3

000X0XXX0X00 = 3 Consecutive Occurrences (X0, XXX0, X0 )
3

XX000X0X0000 = 1 Occurrence & 2 Consecutive Occurrences
1 2

X0X000X00X0XX0X00 = 2 Consec Occur & 1 Occur & 3 Consec Occur
2 1 3


Another Example:

If Input File ( this is one of my original input files):

1 0
2 0
3 X
4 X
5 X
6 X
7 0
8 X
9 0
10 0
11 0
12 0
13 0
14 X
15 0
16 0
17 0
18 X
19 X
20 X
21 0
22 0
23 0
24 0
25 0
26 X
27 X
28 0
29 X
30 X
31 X
32 X
33 0
34 X
35 0
36 0
37 0
38 X
39 0
40 X
41 0
42 X
43 0
44 X
45 0
46 X
47 X
48 0
49 0
50 0

If we arrange in Line ( Actually, we don't need to arrange in line when implemented in code, this is just make easy to understand what I want):
00XXXX0X00000X000XXX00000XX0XXXX0X000X0X0X0X0XX000

then we can determine the consecutive occurrence:

00XXXX0X00000X000XXX00000XX0XXXX0X000X0XXX0X0X0XX000
2 1 1 3 5


So, Desired output is:
2
1
1
3
5


Thanks,

The following awk script gives the expected output for the sample 50 row file

Code:

BEGIN {state=count=0}
{
 if ( $2 == "X" ) {
    if (state == 0 || state == 2) { state=1; count++ }
 } else {
    if ( state == 2) { print count; state=count=0 }
    if ( state == 1) { state++ }
 }
}
