Shell Programming and Scripting

Hi,

I have a line where i need to get certain part of it.. example..

text txt tt: 1909

thats how exactly it looks and all spaces are to be counted.. i need to retrieve 1909..

Thanks

Code:

s/^.* //;

What do you mean spaces are to be counted? Do you need to know how many spaces are there between the "tt:" and "1909"? Are there always three words here? Is it always the last word in the line?

Possible solutions, each all does roughly the same thing:

Code:

  m/:\s*/ && print $';
  m/:\s*(\d+)/ && print $1;
  m/^\S+\s+\S+\s+\S+\s+(\S+)$/ && print $1;
  chop; ($junk,$year)=split(':\s+',$_,2);

Of course, you won't need to fire up perl just to do this.

Code:

  cut -d ":" -f 4

would generally do the trick. So would

Code:

  awk -F "[: ]*" '{ print $4 }'

OP is interested to extract the digits after the last space from the literal
which turns out to be the digits after the space.

yes matrixmadhan is rite.. i just need to retrieve the number '1909'....

thanks

Hey can you explain me what does this do .. thanks again!

So why not just hard-code "1909". Anyway, his perl solution will fail if there are any spaces after the year. Better to use:

Code:

 s/^.*(?:\S)//;
