I have a log.txt file which contains 20k lines. Each line having numbers and there xyz plane coordinates and they are separated by sets. Sets can be identify by there names as ABC_1, ABC_2 and so on in the log.txt

From this log.txt file I want to segregate all sets data in to individual Text files, which should contain all data from set (eg. ABC_1).

My log.txt looks like below.

ABC_1: 
1, (xyz coordinates)
2, (xyz coordinates)
3, (xyz coordinates)

 .... Continue
ABC_2: 
101, (xyz coordinates)
102, (xyz coordinates)
103, (xyz coordinates)

 .... Continue
ABC_3: 
201, (xyz coordinates)
202, (xyz coordinates)
203, (xyz coordinates)

.... Continue
ABC_99: 
9991, (xyz coordinates)
9992, (xyz coordinates)
9993, (xyz coordinates)

.... Continue

I want to create a script which can give me 99 individual text files from a single log.txt file and which should be named as set name ABC_1.TXT, ABC_2.TXT ... to ABC_99.TXT from log.txt.

  • I assume (?) you want the contents of new files to be the intervening lines? Or empty files? – Jeff Schaller May 5 '18 at 12:04
  • With duch questions you should always provide both example input and example output. – Hauke Laging May 5 '18 at 13:23
  • Possible duplicate of text processing rows to columns for a block – αғsнιη May 5 '18 at 13:45
  • what else you need more than just awk '/^ABC_/{N++;next} {print >"ABC_"N".txt"}' infile (assuming the bocks are sorted with # in ABC_# otherwise awk -F: '/^ABC_/{fname=$1".txt";next} {print >fname}' infile ) and that you can find in the answer in flagged question except you no need paste them which you can ignore it? – αғsнιη May 6 '18 at 8:25

With csplit

csplit -s -b %d.txt -f ABC_ Log.txt /ABC_/ {*}
  • you need -z option to remove empty file(s) thought. – αғsнιη May 6 '18 at 8:37
  • @αғsнιη yes and no. this way we get a empty file ABC_0.txt and we can remove it. with -z ABC_0.txt contain ABC_1 and so on. – ctac_ May 6 '18 at 9:13

Awk solution:

awk '/^ABC_/{
         if (fn) close(fn); sub(":", "", $1);
         fn = $1".txt"; next
    }
    { print > fn }' Log.txt
