Is there a nifty awk/sed one-liner to do this operation?
General :: Display Specific Block Of Contents Or Lines In Output?
Apr 23, 2010Consider a situation in which you want to display only specific lines of contents from a file or of a command's output. Yes, we have head and tail commands. But, how to view all the lines of a file except the last one or vise versa when we don't know the count of lines in advance?
Consider this output:
Code:
[root@localhost ~]# ps au | grep bash
root 6316 0.0 0.0 4672 1440 tty1 Ss+ Apr22 0:02 -bash
root 20847 0.2 0.0 4672 1432 pts/0 Ss Apr23 0:12 -bash
root 21167 0.0 0.0 3920 660 pts/0 S+ 01:00 0:00 grep bash
Here, I don't want the last line (in italic) to be included in the result since the last line is due to "grep bash" in the devised command "ps au | grep bash". Well, we can rewrite the devised command:
Quote:
"ps au | grep bash | head -n 2"
But, again, here we are specifying the count of lines to be included. But, in the presented problem we don't know any count in advance!
General :: Filtering Out Duplicate Lines From A Find/grep Output
Mar 22, 2010I have some big files of logs that contain errors printed by an app. They are most of the time relevant, however most of them are similar. So i figured i could check what happened between a time interval with a find.
Im using this one
Code:
And I get an output similar to this one.
Code:
Is there a way to condensate the output lines to get only one or two, indicating the start and last occurrence of a block? Or I need to create a program to do so?
Because right now I get thousands of similar lines, but when I'm scrolling through them i sometimes miss relevant information that i would've otherwise noted if it wasn't all that spammy.

View 1 Replies View RelatedUbuntu :: Prevent Writing New Characters In Beginning Of Output Lines
Aug 5, 2011In Windows's CMD when you execute a command and then start writing the next one (while still executing the former one) the characters remain in the buffer and they all come up nicely to the new line once the previous command has been executed. In Ubuntu when I do this the newly typed characters annoyingly get in the beginning of the previous command's output lines. I don't really understand why isn't the default method as in Windows's CMD. I mean otherwise almost _everything_ sucks with it when compared to Unix/Linux shells/terminals (commands are longer, syntax is annoying, etc.) So I'd like to know how to do this in both Bash and Zsh.

Programming :: Remove Specific Lines From File
Jan 21, 2011I'm trying to come up with ideas for a simple way to strip a specific "entry" from a text file.I know tools like sed and perl can remove specific lines from a file but I haven't been able to come up with an elegant way to do my group of lines.In my file, the first "Location" line and the "SVNPath" line should be unique every time... but are they enough to strip out the whole set of the group plus the trailing one line of white space separating each group? Add to this, my file will grow as new entries are added (always appended to the end) but new entries will have the same formatting.
