That should print anything between FOO and BAR, right?
Well, let's say I have file.txt that contains just one line "how are you today?".
Then I run something like the above and get:
Code:
$ sed '/how/,/today/p' file.txt
how are you today?
how are you today?
It prints the line twice when I was expecting it to print just "are you".
I tried several text files with different content and also played around a little bit with quoting and regexps and in every case I got the line or the entire text duplicated.
I'm pretty sure the problem is mine and not sed's but I can't figure out what I'm doing wrong.
Any ideas?

Thanks to all of you out there. Reading this forum got me out of trouble many times
I have a text file that I want to search for repeated lines and print those lines. These would be lines in the file that appear more than once. Is there a way to do this?
Thanks (4 Replies)
I have attached a file with few records. First 2 characters of each record are binary characters. I can remove it by
and it works fine. But
is behaving differently and removing more than expected characters. Can someone help me in accomplishing it through sed? Thanks in advance. (13 Replies)
if I wanted to know if the word DOG(followed by several random numbers) appears in col 1, how many times will that same word DOG* appeared in col 2? This is a very large file

Hi I'm having a problem with a sed command that I thought I was using correctly but apparently that's not the case.
I was hoping someone here could point out what it is I am doing wrong?
I am using the print, no print option for a matched pattern in sed. Everything seemed to be working fine... (5 Replies)

HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted
by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications.
SEE ALSO shtool(1), sed(1).
