UNIX for Dummies Questions & Answers

hmmm.. i tried my luck with gawk and also swapping the both files ,
i am using Suse . is it possible to install nawk on Suse , i browsed said nawk for solaries is gawk or awk

can you please tell me the version of nawk you using will that make any difference ?

You have suse, therefore your awk is gawk by default.

Did you try removing carriage returns like he suggested?

gawk should be fine.
The file2.txt that you posted does have ^M-s at the end of the lines.
I'm not sure if it's the result of ftp and attaching to this thread or not...
Follow the directions above to remove ^M-s from the ORIGINAL files you're using.

woww it worked after doing

Code:

 tr -d '\015' < oldfile > newfile

on both files

what exactly is "^M-s" you asked me to check at the end of the lines ?

i greatly appreciate your help and patience ...

They are these.
These forums contain wealth of the information - start using the 'Search' functionality.
Good to hear it's worked out for you.

thanks a ton Vgersh

it finally worked and now i will implement this on complete folder which contain 90+ files ,


there is one more issue i have with my job , lets assume if the change is there in 2 continuous lines then
** my change start point **
line x
** my change end point **
** my change start point ** line x+1
** my change end point **
is it possible to write the tags only once as below output
** my change start point **
line x
line x+1
** my change end point **

i got an alternative as am not expert in awk

1) with the output of the above i will search for the lines below and delete them , this can be alternative if the awk does not permit me
** my change end point **
** my change start point **

vgersh please suggest your opinion

thank you !!

Code:

BEGIN {
  tab=sprintf("\t")
  space="([ ]*|" tab "*)"
}
FNR==NR{f2[FNR]=$0;next}
{
  s1=$0; s2=f2[FNR]
  gsub(space, "",s1);gsub(space, "",s2)
  if ( s1 == s2) {
      if (sep) {
        print e ORS $0
        sep=0
      }
      else print $0
  }
  else {
      if (!sep) {
         print s
         sep++
      }
      printf("*%s\n%s\n", f2[FNR],$0)
  }
}
END {
  if (sep)
    print e
}
