Hope this sed question isn't too offtopic, but....
I want to grab individual lines of text with sed to be filtered/parsed
from text files coming in through my SmartList/Procmail setup.
So far I want to:
line=`sed -n -e ' '$count'p' < file.txt`
This is fine, I can increment $count to go get the next line when
I am ready for it. Trouble is I don't know when file.txt runs out
of lines. If I have $count set to 50 but there is only 49 lines in
file.txt, is there an error code I can check so I know I have reached
the end of file.txt?
While I am here, it seems reading lines from file.txt one at a time
might generate alot of disk accesses. Is there a way to pull file.txt
into a variable and have sed grap lines from the variable, or can
sed only read files on the disk?
