using Zgrep and awk to parse a .tgz file and print first row

Question

I would like to use Zgrep and Awk to print specific lines.

I use the below script. However, I am not able to print the specific line requirement.

zcat SYS.20210519.tgz | awk '/11055/ && /2.5.5.5/'

It would be nice if someone could help. Thanks.

File name : SYS.20210519.tgz

File INPUT :

20210519 072532  11055  ERROR   Connection is not writable, error[grpId[2.5.5.5/49.3.14.13:17126] connId[142706130] testMode[true] connInfo[ConnInfo[connId=142706130, connGrp=2.5.5.5/49.3.14.13:17126,

File output (Needed) :

20210519 072532  11055  ERROR   Connection is not writable, error[grpId[2.5.5.5/49.3.14.13:17126]

Welcome to SO, thanks for sharing your efforts, please do add your samples of input and expected output more clearly in your question to make it clear. — RavinderSingh13, May 25 '21 at 11:49
Thank you for responding. I have edited my question now with the input file and expected output file. Thanks — Vijay Joshua, May 25 '21 at 12:02
In what way is your script failing? It **would** print the line you want (plus maybe some others you don't want but idk if that's the problem you're asking about). — Ed Morton, May 25 '21 at 14:00

With your shown samples, could you please try following. Using zcat to read your Input_file then sending its output as standard input to awk program. Where using match function to match regex, which will print till value of error[grpId till ] occurrence.

zcat Input_file | 
awk 'match($0,/.*error\[grpId\[[^]]*\]/){print substr($0,RSTART,RLENGTH)}'
