As much as I didn't want to ask a sed question, especially considering there's already one on this page I've looked as best I could and cant find the solution. Id like to use sed to replace occurrences of a pattern but exclude two or 3 specific lines that are not consecutive. For example I know with 1,10 i could exclude the first 10 lines, what is the syntax if I just wanted to exclude line 3 and 7. The sed command I'm working with right now is for rearranging Ethernets.
cat /etc/udev/rules.d/70-persistent-net.rules | sed -e '/'"$found1fullmac"'/!s/eth1/'"found1eth"'/' > /etc/udev/rules.d/70-persistent-net.rules
I would like to replace $found1fullmac with two variables representing line numbers to exclude from the replacement.
A function by name abc is called in many files. I want to copy all the lines with the function call to an output file.A simple grep on function name doesn't help me as the function call is spanning across multiple lines as follows:
abc(parameter1, parameter2, parameter3);
So I want to copy all the three lines (till semicolon) to the output file.The problem is because there are more than 200 calls for the same function and I cannot do it manually
I need to insert 3-4 lines of text to the beginning of a text file. The file is a largish MYSQL dump, the result of a backup shell script. This shell script should insert the required text.I've wrestled with sed, but lost.
Trying to remove lines from a syslog text file that have duplicate strings

got the same thing in terms of a u: number but the issue is I need to remove duplicates and just leave one and the file has multiple duplicates of different u: numbers and it's 14,000 lines long. can anyone tell me if I can use awk? sed? or sort for something like this to? removing lines that have a certain string in there that's a duplicate.
To save on the writing of WAY to many files with very little in them, I want to put it all in one file and read a specific few lines. There will be six variables to be read at a time. Format is as such:
//Set 1 string name 5 12
From name to 5th number is a set. The name will be of different lengths for each set. This will be a big file of probably 40+ sets. My problem lies in reading one and only one set be it set 5 or set 34. It needs to be done in C++.
I'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.
I'm trying to extract specific lines from a flat file. I need lines that fall within a range of coordinates. The -F can be either ! or = If the line is in this set range I need all of the data on that line. ranges lat 36 to 39 and longitude -74 to -84
I have text file with say 1000 lines.And I want to display lines numbered 100, 203 and 297 using a script/ command.How can I do this ?I can print a particular line using:sed -n '100p' file1 (where file1 is input file).
I have a plain text file with 360 lines of varying length text. How do I add a comma or other symbol to the end of each line so that I can convert the file to csv format that I can open in a spreadsheet (45 rows, 8 columns). That means each 8 lines of text forms 8 columns, with 45 rows.
I want to be able to check the contents of a text file for a specific string and remove it from the file from the command prompt. I would basically be searching through a number of files and if a specific string is found I would like it removed automatically. pretty much a find and replace, were the replace is nothing. any one got any ideas on how you would do this. I already have the search part sorted just need to be able to remove the string I don't want from the multiple files.
Contained within each of these 67 text files is about 1 million urls. Yes. I have 67 text files that contain 1 million lines of urls each. I am sure I am swimming in duplicates. I tried opening one text file and clicking sort ----->remove duplicates. Now Gedit is not responding my processor is maxed out to 100% and I think I am finally ready to delve into some command line code. Can anyone give me idiot proof instructions on how to sort the duplicates out of each one of these 67 text files? How about no duplicates across all 67?
I need to chop of the top 30ish lines of several log files until a line starting with "Initialization completed."The trouble is that it's not always the same amount of lines that need to be deleted, and they don't always contain the same information, which is why I would need to delete everything priorhe line starting with "Initialization completed."Right now I have a little script I wrote based on looping each file through several "grep -v" commands with each known pattern of lines I want to ignore, but it is tedious and I have to inspect each file afterwards to make sure nothing is left from above "Initialization completed
i have a big file of random numbers i generated at some point in time, after working with it with different things(how fun that was)... i want to remove duplicate lines and i'm not sure i'm doing this right
I need to create a script to count the number of lines from a text file . The output must be put on another text file (no_lines.txt) and in this file i need to generate from the script this output :"File $FILE has $NO_LINES lines ".
I have a text file which stores the list of files & dir, I want to get only file's extensions from this file & want to store it in another file.eg, below is the file's contents & from it I want to get the extensions sh, pl & h & want to store it in another file. Also I don't want directory list.
A scripts/services_restarter.sh A scripts/svn post_commit scripts A scripts/tmp/
This should be simple but I can't seem to find what I am looking for.I want to search a text file for the existence of certain strings and execute a command if they exist, something along the lines of:
if <string> exists command or
if <any member of this list exists> command
I know how to manually search a file with grep, cat, etc., but the "if this exists" part eludes me.
Consider 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?
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:
"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!
