capture output of file and send last string thereof to new file
Hello,

If I run a program from within shell, the output is displayed in the command line terminal. Is there a way I can capture that output and choose only the very last string in it to send it to a new file?

Thank you

you can redirect the output of acript to a file and then by using tail you can get the last line
Code:
 
scriptname >> filename
tail -1 filename

Thanks you
I did :
scriptname | tail -1>>newfile.dat

but what gets copied to newfile.dat is that last line, instead of the last string in the last line

can you post the last line and what exactly you want from that line

Define string. Do you mean the last aggregate of characters with no spaces?
Code:
scriptname | tail -1  | awk '{ print $NF }' >>newfile.dat

In terms most of us here understand a string can be a line of text/letters as well.

Sorry for the confusion.
I mean last token in the line.

Thank you so much jim for the code.

if you wanted that then no need of tail -1 i guess
Code:
scriptname|awk '{END{print $NF}' >> filename
