Help with egrep or grep command to meet multiple criteria

Shell Programming and Scripting
1

Hello,

I"m a newbie :). I hope I can learn from the scripting expert.

I'm trying to use egrep and grep commands to get the total count by meeting both criteria. So far, I haven't been able to do it.

if robot = TLD and barcode = AA, then final count should be 2
if robot = TLD and barcode = BB, then final count should be 1

I tried the following command below, but it picks up everything with TLD and AA. I would like it to pick up only if both matches.

egrep 'robot.*TLD | AA'  | wc -l

Are there any suggestion or recommendation?

Thanks so much in advance.

Filename output of testing.txt below:

media:    AA12345
robot:    TLD library
barcode:    AA12345
volume:    TESTING

=================

media:    AA56789
robot:    NONE library
barcode:    AA56789
volume:    TESTING

=================

media:    BB88888
robot:    TLD library
barcode:    BB88888
volume:    TESTING

=================

media:    AA44444

Not so clear, give us the final output you prefer.

3 
$ ROBOT=TLD
$ BARCODE=AA
$ sed -n "/robot:.*${ROBOT}/{N;/barcode:.*${BARCODE}/s/\n//p;}" file | wc -l
       2

$ ROBOT=TLD
$ BARCODE=BB
$ sed -n "/robot:.*${ROBOT}/{N;/barcode:.*${BARCODE}/s/\n//p;}" file | wc -l
       1

I was unable to understood your full requirement.But,if you want to match both TLD and AA in same line.Then,you use the following.

egrep "robot.*TLD.*AA"| wc -l

Thanks rdcwayx, anbu23, and vivekraj for your response.

The output is very large, but I will trim it down to 6 records in the file.

I attempted to use anbu23 code, but it kept returning with 0 count.

sed -n "/robot type:.*TLD/{N;/barcode:.*AA/s/\n//p;}" testing.txt | wc -l

I hope I can make this one more clear.

There are 6 records in the testing.txt file. For each record, I would like a count if it fits the criteria with barcode of AA* and robot type of TLD*.

Based on the 6 records, I should get a total count of 4 that fits the barcode of AA* and robot type of TLD*.

barcode AA0379, AA0400, AA0500, AA0700 all fit the criteria.

Thanks in advance.

How will the code work if you change your input??

sed -n "/barcode:.*AA/{n;n;n;/robot type:.*TLD/p;}"  file | wc -l

Thank you so much anbu23. It works great! I was able to understand the logic behind your script.

Only awk:

awk 'BEGIN{RS="=+";FS="\n"} /barcode.*AA/&&/robot.*TLD/ { sum++ } END {print sum}' file
9

Only grep... and grep. This will fail if the lines don't appear exactly as they did in your example, as will sed. The awk line doesn't appear to.

# grep -B 3 TLD testfile | grep -c AA
4
#

It greps TLD and looks up 3 lines and counts how many "AA"s.

Thanks rdcwayx and fubaya for your suggestion. The sed command works beautiful, but I'm curious to test your solution as well.

Again, thank you.
