Shell Programming and Scripting

Hello,
Thanks in advance for the query.

There is a log file abcd.log which has multible line like this.

"hello1" , "hello2", "hello3" , "hello4" , "hello5"

I want to grep for the lines which has "hello4" & "hello5" and use "hello2" to grep the same log file again.
All these should happen on the fly.

How do I grep using a string in the result I get here.

Please show part of your input data and the desired output.

This is my log file.

"hello1" , "hello2", "hello3" , "hello4" , "hello5"
"hello1" , "hello6", "hello7" , "hello8" , "hello9"
"hello1" , "hello12", "hello13" , "hello14" , "hello15"
"hello1" , "hello22", "hello23" , "hello24" , "hello25"

"hello2" & "hello3" are the string which I will know in advance before the log is generated.
My output should contain "hello1"

Try this

awk '/hellox/ && /helloy/' <filename.txt> | awk '{ print $1 }'

awk '/hellox/ && /helloy/ {print $1}' <filename.txt>
