This better goes with an example (yes, from an .srt-file):

231 00:13:35,230 --> 00:13:37,120 - Oh, my sister got me into it. 232 00:13:37,129 --> 00:13:38,269 - Yeah? 233 00:13:37,129 --> 00:13:38,269 Is that her? 234 00:13:40,049 --> 00:13:41,090 - Yeah.

The line 00:13:37,129 --> 00:13:38,269 appears twice and I want to connect the two sections. So it would have to work like this:

  • check all lines containing " --> "
  • if it matches the previous such finding remove this line and the two lines above

So the result would be:

231 00:13:35,230 --> 00:13:37,120 - Oh, my sister got me into it. 232 00:13:37,129 --> 00:13:38,269 - Yeah? Is that her? 234 00:13:40,049 --> 00:13:41,090 - Yeah.

This goes way beyond my sed-skills. It probably works with that internal buffer and pattern space? Well, I don't even have a clue how to approach this...

I'd use awk for that:

$ cat tst.awk (!NF) { # blank line b = ""; f = 1 # empty buffer, start buffering } /-->/ { # timestamp f = 0 # stop buffering if (p == $0) { # same timestamp next # discard buffer, start over } p = $0 # save timestamp printf "%s", b # print buffer } f { # buffering enabled b = (b $0 ORS) # buffer line next # start over } 1 # print line

outputs:

$ awk -f tst.awk file 231 00:13:35,230 --> 00:13:37,120 - Oh, my sister got me into it. 232 00:13:37,129 --> 00:13:38,269 - Yeah? Is that her? 234 00:13:40,049 --> 00:13:41,090 - Yeah.

I think the awk version is much better, but here is a bash version just for fun : )

out=""; while read line; do if [ "$prevtime" != "$line" ];then out="${out}${line}\n"; else out="$(echo -e "${out}"|head -n -2)\n"; fi ; echo "${line}" |grep -q "\-\->" && prevtime=$line ; done <test.srt ; echo -e "$out"
