UNIX for Dummies Questions & Answers

Hello Friends -

I am trying to grep certain messages that have a time slot like this:

Code:

 
MyRate=33FC|SystemDEF=445DE|Calc=33W2|Time=15:50:24

I am trying to grep everything after Time=15:50:26 including SystemDEF=E2S and Calc=33W2 into a file called myrate.dat

Not able to grep everything after the time, can you help?

Thanks again

Not clear. How and where does SystemDEF=E2S come into play? You could use awk like

Code:

awk -F"|" '$4=="Time=15:50:26" {P=1} P' msgfile >myrate.dat

grep does not have less than, greater than, if, then, and, etc. So it's not much use for comparing time.

awk does, though. If your times are in HH:MM:SS format they are easy enough to compare.

If your 'time=' field is always the last field:

Code:

awk '($NF >= ("Time=" TIME))' TIME="15:50:24" filename

Thank you.

I am not attempting to compare time.

However, the file contains many messages as above example, each have a time field with a different time.

RudiC: the file will contain a value called SystemDEF=E2S


Hence, I am trying to get:

1. Any message that came after 15:56:26
2. That also contained the value SystemDEF=E2S
3. And also contained the value Calc=33W2

Hope i am able to make sense!

Thanks

Code:

awk '!f&&/Time=15:56:26/{f=1;next}f&&/SystemDEF=E2S/&&/Calc=33W2/' file

And how do you get at records AFTER that target time? Assuming that records are in increasing time order, try

Code:

awk -F"|" '$4=="Time=15:50:26" {P=1} P && $2 ~ /=E2S$/ && $3 ~/=33W2$/' msgfile >myrate.dat

Thank you everyone.

Thanks Yoda, may the force be with you, I have one question:

What if i want to search with same parameters as before but

Time should be between 15:25:20 and 16:33:45
