Your help will be highly appreciated

If the invoice number is all on the same line and the format for Invoice Number is constant, then all I would do is:

/home/arbor> cat PH0034090202314800030IM-001 | grep Number:

or

/home/arbor> grep Number: PH0034090202314800030IM-001

Both of these should output only the lines containing Invoice Number:

If you want them outputted to a file, then use the > operator like so

/home/arbor> grep Number: PH0034090202314800030IM-001 > InvoiceNumbers.txt

Good luck

To grab all the invoice numbers, the grep command won't work. Although it looks the file rooh posted contains many lines, all that text is actually only on three lines, with the invoice numbers only occuring on the last two...

oombera, as far as it only appearing as 3 lines, did you copy and post in to text editor and remove word wrap and saw 3 lines? If that is the case and it is indeed only 3 lines, then grep will not really be much assistance.

rooh, can you confirm whether oombera is correct about it being only 3 lines, or can you post the same output as a text file?

Yeah oombera is right and grep doesn't work

I'm not sure exactly how to help with this...

If you're sure the Invoice number will always be on the last line of the file and that there are no other colons (:) on the line, then you could use:

tail -1 text | awk -F":" '{print $2}'

If you're sure the last line will always be the same length, then you could use:

tail -1 text | awk '{print substr ($0, 280, 71)}'

From looking at your data, I don't think you could make either of these assumptions, but I'm not sure what else to suggest.

My thoughts are that you could do this with regular expressions.

egrep supports regular expressions (as does PERL, PHP, etc.)
