[SOLVED] Trying to store the output from awk

gsr_kashyap · 06-08-2017, 09:44 AM

Hi All,

I have a file containing

abc xyz pqr 300
asd zyz sdf 400

I am using awk to get the output 300
- awk '/abc/ && /xyz/ && /pqr/ {print $NF} /home/file.txt

I got the output as 300 now I have to store the 300 value into a integer to comapre

int1=$(awk '/abc/ && /xyz/ && /pqr/ {print $NF} /home/file.txt)
I have even tried redirecting the output ">> int1"

but nothing seems to work

Thanks in advance.

You seem to be missing the closing quotation mark for that:

Code:

int1=$(awk '/abc/ && /xyz/ && /pqr/ {print $NF}' /home/file.txt);

Turbocapitalist gave good advice in post #2.

Consider that the order of the character strings may be important and cause unexpected results.

With this InFile ...

Code:

abc xyz pqr 300
asd zyz sdf 400
abc pqr xyz 500

... this awk ..

Code:

result=$(awk '/abc/ && /xyz/ && /pqr/ {print $NF}' $InFile)
echo "result="$result

... and this awk ...

Code:

result=$(awk '/abc xyz pqr/ {print $NF}' $InFile)
echo "result="$result

... are not equivalent.

No problem.

Depending on what you are trying to do, you might associate patterns with specific fields.

Code:

awk '$1 ~ /abc/ && $2 ~ /xyz/ && $3 ~ /pqr/ {print $NF}' /home/file.txt
