Question

I’m trying to use the following awk script to count every 1000 records from file named file.txt and enclose those records between brackets

content of file.txt

12345

23456

43567

awk '{ printf $0 " " } NR%1000 == 0 { print "" }' file.txt | sed 's/.*/(&)/'

output

(12345 23456 43567)

I need to assotciate this output with mysql bulk delete statement such as the following

Delete from ReportingDetail where ReportingDetailID IN (12345,23456,43567); 

1. I’m unable to add “Delete from ReportingDetail where
   ReportingDetailID IN” to the birnining of every line.
2. I’m unable to add “,” between records.

Your help is highly appreciated!

You can do this only with sed:

sed -e 's/ /,/g' -e 's/^/Delete from ReportingDetail where ReportingDetailID IN (/' -e 's/$/)/' file.txt

E.g.:

$ echo "1 2 3"|sed -e 's/ /,/g' -e 's/^/Delete from ReportingDetail where ReportingDetailID IN (/' -e 's/$/)/'
Delete from ReportingDetail where ReportingDetailID IN (1,2,3)

Edit – for your update (i.e. when you have numbers on different lines), just prepend what you already had:

awk '{ printf $0 " " } NR%1000 == 0 { print "" }' file.txt | sed -e 's/ /,/g' -e 's/^/Delete from ReportingDetail where ReportingDetailID IN (/' -e 's/,$/)/'

E.g.:

$ echo -e "1\n2\n3"|awk '{ printf $0 " " } NR%1000 == 0 { print "" }'|sed -e 's/ /,/g' -e 's/^/Delete from ReportingDetail where ReportingDetailID IN (/' -e 's/,$/)/'
Delete from ReportingDetail where ReportingDetailID IN (1,2,3)

You can also do that without awk like this:

$ echo -e "1\n2\n3\n4"|tr "\n" " "|sed -e 's/ /,/g' -e 's/^/Delete from ReportingDetail where ReportingDetailID IN (/' -e 's/,$/)/'
Delete from ReportingDetail where ReportingDetailID IN (1,2,3,4)

Note the echo I used is just for testing, i.e. this is what it produces:

$ echo -e "1\n2\n3\n4"
