Awk: Page number with total number of pages, EG Page 1 of 5
So I've worked how to add page numbers based on regex. It's using the footer text.

How do we get the total amount added so we have page number with the total number of pages?

Quote:
awk '/ This is the last line of the page!/{a++;$0=$0"\n Page No:"a}1' textfile1 > textfile2
Desired output: Page No:1 of 5

Thanks in advance.

process the file twice: first for calculating the total, and the second to print your summary.

Thanks for this, this works but it looks like the whole document is being repeated?

Code:
#!/usr/local/bin/awk -f
#
#

BEGIN {FS=";"}

/This is the last line of the page/{a++;$0=$0"\n                          Page No:"a}1
/This is the last line of the page/{a++;$0=$0"\n                          Page Total:"a}1

Hmmm... I don't quite understand the code and this is NOT what I meant...

Code:
awk -F';' '

FNR== NR && /This is the last line of the page/{ total++;next}
/This is the last line of the page/{printf("Page No:%d of %d\n", ++page, total)}' textfile1  textfile1  > textfile12

I'll let you work out the exact formatting as you want...

Thanks for this.

Can you please explain the last line of code using the original file twice before the last output?

Quote:
/This is the last line of the page/{printf("Page No:%d of %d\n", ++page, total)' textfile1 textfile1 > textfile12
Using your snippet solves the issue although the final outfile only has the page numbers in a file but nothing else.

Quote:
Page No:1 of 3
Page No:2 of 3
Page No:3 of 3

Code:
# when a string "This is last..." is found, print the CURRENT page count (page) incremented by 1 (++) and the total # of pages (total)
/This is the last line of the page/{printf("Page No:%d of %d\n", ++page, total)' textfile1 textfile1 > textfile12

As I noted, you'll have to format the final print out based on your desired format.
It's hard understand what's your desired output should look like...
What is it?

Thanks again,

That string is actually the last line in a report print. It's a footer so every single page will have that line. The idea was to insert page numbers "Page 1 of X" on the next line under the footer string, counting each string as one page, it will only appear once per page.
