Say I have a huge text file (>2GB) and I just want to cat the lines X to Y (e.g. 57890000 to 57890010).
From what I understand I can get a somewhat similar behavior by piping head into tail or viceversa, i.e.
I am trying to find a Unix command (combination, maybe) on how to continuously display a file of its last several lines of contents.
In the same spirit as this other question: cat line X to line Y on a huge file:
Is there a way to open from within Emacs (and
show on a buffer) a given set of lines (e.g. all lines between line X and Y) from a huge text file?
E.g.
Log files are important when debugging or just to check how a system is performing, we usually use cat to list the log on the screen, but if we want to see a live view of the log file, the command is:
tail -f /var/log/logfile.log
Is there a simple way I can echo a file, skipping the first and last lines? I was looking at piping from head into tail, but for those it seems like I would have to know the total lines from the outset. I was also looking at split, but I don't see a way to do it with that either.
I have an application that is logging to a plain text log file (myapp.log) but it doesn't seem to be writing new line characters at the end of each log entry. If I execute a command like tail -n 50 myapp.log I actually receive hundreds of "lines" of text (log entries).
This log file is very large, roughly 1GB, who knows how long ago the last CR and/or LF was inserterd.
Is there any way to add lines to the pattern space of sed?
I know a bit about the N flag, but am not able to use it to do what I want which is:
read a file n lines at a time. If I find a match I quit else move to the next line. e.g.
I am getting the lines from the linux log files and i am displaying in the bowser using django.
They are all displaying as same paragarah but i want to show them with new lines
They display in nelwines if i warp them in <pre> lines </pre> but then my html tags are not rendered properly
is there any way to display that in good format with newlines and html tag rendered properly
Hi,
Suppose I have a file with many lines as follows. Now I want to find the following questions from the file through shell script or commands.
Code:
My name is XYZ. XYZ works for GHT and XYZ is part of PES. GHT is a good organization. XYZ knows swimming. XYZ is also very keen in reading.
