Grep two strings in same line

Ruan Matt

Could you please help me? Look this file below:

[Parsed_showinfo_0 @ 0x55d39a569e00] n:48591 pts:24878592 pts_time:2024.62 pos:120292092 fmt:yuv420p sar:1/1 s:640x360 i:P iskey:0 type:B checksum:292B9CE1 plane_checksum:[F3F98FB2 02828690 02828690] mean:[20 128 128 ] stdev:[27.0 0.0 0.0 ]

...

Using this command =>

grep showinfo file.txt | grep pts_time:[0-9.]* -o | grep '[0-9]*\.[0-9]*' -o > timestamps

I get correctly all pts_time values. But I want to capture "n:X" too! Using grep showinfo file.txt | grep pts_time:[0-9.]* -o | grep '[0-9]*\.[0-9]*' -o | grep n:[0-9.]* -o | grep '[0-9]*[0-9]*' do not work! There are no errors. The output should be something like this:

48591/2024.62
48592/2024.67
48593/2024.71
48594/2024.75
...

Also, to avoid creating a new thread, would be possible convert the second argument (2024.62, 2024.67, etc) to human readable? In this format => hours:minute:seconds.miliseconds? Thank you.

A solution that is more robust to varying ordering of the columns would be:

grep showinfo file.txt | grep -E 'pts_time:[0-9.]+|n:[0-9]+' -o | sed '$!N;s/\n/ /' | perl -lape '$_ = qq/@{[sort @F]}/' | awk -F'[: ]' '{print $2"/"$4}'

Which:

Gets the relevant lines
Uses extended grep to or match the two columns
Use sed to merge those columns to merge the pairs of results on to a single line each (https://stackoverflow.com/a/1513918/1581658)
Use perl to sort those lines alphabetically so out of order keys are always ordered. (https://stackoverflow.com/a/47520200/1581658)
Use the above solution awk not with fixed columns to format (https://stackoverflow.com/a/69391284/1581658)

The awk can be replaced with awk -F'[: ]' '{printf "%d/%02d:%02d:%05.2f\n",$2, $4/60/60, $4/60%60, $4%60 }' as in (https://unix.stackexchange.com/a/34033) to format HH:MM:SS.ss
