Replace Special Character With Next Present Byte
Hi,

First find the special character, from the special character take next two bytes convert the bytes to decimal and replace with next present byte of decimal value times.

E.g.
Code:
Input: 302619ú1A? 
Output: 302619(3 spaces for ú1A)??????????????????????????

Thanks,
Dines

Hi,

The below code failed with below error
"Unrecognized switch: -E (-h will show valid options)."
Could you guide us to change the code to use it in SunOS.

Thanks,
Dines

You're running an older version of Perl try the following:
Code:
$ perl -Mutf8 -e '$value="302619ú1A?";$value=~s/[^A-Za-z\s\d]([\da-fA-F]{2})(.)/sprintf("   %s", $2 x hex($1))/e; print "$value\n";' -
302619   ??????????????????????????

Hi,

Thanks for you reply.
Could you please explain the process how to deal this in a file as multiple occurrence. eg:
Code:
IBM513AMMODú07 ibmyx66mcp00ú06 302619ú1A 00005014072605331600ú0A 980ú32 201407260533160ú14

Thanks,
Dines

Welcome dineshnak,
I don't really see the question clearly, but I have a few to questions pose in response first:-
  • Is this homework/assignment? There are specific forums for these.
  • What have you tried so far?
  • What output/errors do you get?
  • What OS and version are you using?
  • What are your preferred tools? (C, shell, perl, awk, etc.)
  • What logical process have you considered? (to help steer us to follow what you are trying to achieve)
Most importantly, What have you tried so far?

There are probably many ways to achieve most tasks, so giving us an idea of your style and thoughts will help us guide you to an answer most suitable to you so you can adjust it to suit your needs in future.


We're all here to learn and getting the relevant information will help us all.


Regards,
Robin
