how to remove new line

[domenicodl]

Hi,
I would lie to know how to remove the new line from a string.
Googling I found the command prints(%s, $0) that is not what I'm looking for.
I have to parse a file like the following one

000020E0 3D 20 00 40 lis r9,400000
000020E4 39 29 A0 00 addi r9,-6000
000020E8 80 09 00 00 lwz r0,00(r9)
000020EC 7C 03 03 78 mr r3,r0
000020F0 81 61 00 00 lwz r11,00(r1)
000020F4 83 EB FF FC lwz r31,-04(r11)
000020F8 7D 61 5B 78 mr r1,r11


Since I want to count the occurrence of each "rx" string (e.g., r1 appears 1, r9, 3 times and so on)
The fragment of code with which I find the string rx is the following
register = $7;
split(register,r,",");
for (i in r){
sub(/\)/,"",r); #I remove "() -" that I do not need
sub(/\(/,"",r);
sub(/\-/,"", r);

Now from the r I have to remove also the new line, how can I do it?
of course I can't use the command printf(%s, r) because I need to use r for further processing and not to print it.
Thank you in advance.

Hi

I would use abit different approach :

[teal]{[/teal]
  register [teal]=[/teal] [navy]$7[/navy][teal];[/teal]
  [b]split[/b][teal]([/teal]register[teal],[/teal]r[teal],[/teal][fuchsia]/[,()-]/[/fuchsia][teal]);[/teal] [gray]# <- other unwanted characters here[/gray]
  [b]for[/b] [teal]([/teal]i [b]in[/b] r[teal])[/teal]
    [b]if[/b] [teal]([/teal]r[teal][[/teal]i[teal]]~[/teal][fuchsia]/^r[0-9]+$/[/fuchsia][teal])[/teal]
      rcount[teal][[/teal]r[teal][[/teal]i[teal]]]++[/teal]
[teal]}[/teal]

There is easy to add more unwanted characters as delimiters for [tt]split()[/tt], for example the newline : [tt]/[,()[highlight]\n[/highlight]-]/[/tt] .

But note that Awk says :

RS The input record separator, by default a newline.

So newlines should be consumed by default as record separators. Are you sure those are your problems ?

Hi feherke,
thank you for your reply. I think my problem is the new line because after splitting and removing "()"if I use "length" on "00r1" I get 5 rather than four. The same for r11 at line 0x20F8.
However, I tried your code fragment, it doesn't work properly.
For example on the line 0x20F8 it doesn't coun't the string r11.
If I understood your script correctly. it count all the string in the form rx where x = 0,...,9.
Probably, I haven't been clear formerly, I also need to count the string rxx
e.g. r31, r10 and so on.
Thank you again

Hi

For example on the line 0x20F8 it doesn't coun't the string r11.

It counts it for me on Linux using [tt]gawk[/tt] and [tt]mawk[/tt], in CygWin using [tt]gawk[/tt] and on Windows using [tt]awk95[/tt]. What are you using ?

If I understood your script correctly. it count all the string in the form rx where x = 0,...,9.
Probably, I haven't been clear formerly, I also need to count the string rxx
e.g. r31, r10 and so on.

 +---------- string starts here
 |+--------- literal "r"
 ||  +------ any character between "0" and "9" inclusively
 ||  |  [red]+--- previous entity repeated 1 or more times[/red]
 || / \ [red]|[/red]+-- string ends here
 ||/   \[red]|[/red]| 
/^r[0-9][red]+[/red]$/

Hi

The disassembler file attached to your thread271-1655176 reveals the problem : there are carriage return ( [tt]\r[/tt] ) characters, not new line ( [tt]\n[/tt] ) characters. Add those to the regular expression as [tt]/[,()[highlight]\r[/highlight]-]/[/tt] and will work.

uhm, ok I will check the code around the code fragment you provided to me. Sorry for making you waste time.
Thank you.

Thank you,
it 's very difficult to find people kind like you
