Linux Help required in writing the regular expression.
Code:
1 1982        1          testing            init.cc  3001     Apr 25 2014    09:56:13.617

For the above lines I need to have the reqular expression for the line
1 1982 1 testing init.cc 3001 Apr 25 2014 09:56:13.617
so that I get the below two lines
Code:
1 1982        1          testing            init.cc  3001     Apr 25 2014    09:56:13.617

Hello,

Following may help also.


Code:
awk '/^1 1982.*09:56:13.617$/ {getline; print $0}'  file_name

Output will be as follows.

Code:
Task(0x5bac5060) tRestart (stack st:0x5bace000, end:0x5bac8000) deleted


Thanks,

Thanks Singh for the response.

But that is not what i need.

I need the two lines to be displayed.
1 1982 1 testing init.cc 3001 Apr 25 2014 09:56:13.617 Task(0x5bac5060) tRestart (stack st:0x5bace000, end:0x5bac8000) deleted


Also the numbers in the first line can vary.

So you just want to print all lines...?

What, exactly, do you not want to print?

As i have explained earlier i need to get write the reqular expression for the first line so that it will read untill it encounters same line i.e., 1st line again.

I might have changed the requirement here.

For example : I have regular expression "^(?!Time).*$" which will read string starting with Time until it encounter the newline. Similar way i need regular expression for the line
" 1 1982 1 testing init.cc 3001 Apr 25 2014 09:56:13.617 "
so that it will read until it encounters the next pattern which is similar to this.

Hope i have made the question clear. Let me know if not.

Emphasis mine.

Until which bits are similar -- How similar? How much difference is allowed? Be specific.

similar to the line "
Code:
1 1982        1          testing            init.cc  3001     Apr 25 2014    09:56:13.617

"
Here the numbers and the strings might change
