How to see the first/last lines in a zip file (like head/tail commands)? The zip file only contains one file of big size.
Also, is it possible to read the lines from the zipped file one by one in C++ programming?
It's not a good idea to unzip it first due to its big size.
how can I set the cat command to read specified lines of a text file,like if I have a text file with 100 lines, who can I say cat only line 23 to 42?

I have several text files that list hundreds or thousands of words each. I need to find the intersect of each of these sets. (i.e. print only lines that occur in each file) Is there a CLI utility that can do this?
View 3 Replies View RelatedUntil now i haven't had to dabble with bash scripts.
I have a program that reads in data files. These are named datafile01_R, datafile01_G, datafile01_B, they then increment, so datafile02_R etc i have about 600 of these. the program reads in 3 data sets at a time from each run, so files_01 r, g, and b.
The program then does its magic, and outputs about 40 different files, depending on the file, they gone to folders named R, G, B, psa, or tracking.
The program itself has configuration files to say where the files should gone when analyzed, there is also the config files that reads in the data sets.
At the moment i have to run one set of data, then go in and manually change the input file location, and run again. But, doing this, even though a different data set, the new set overwrites the old set in one of the output folders. So i need a way to increment the output filenames after they are written and before the program is run again with the new data set.
Usually when I need to replace some lines in a file, the first tool that comes to mind is sed -i:
sed -i 's|tool:.*|tool: some-tool|'
However, it's inconvenient when there are . characters in the replacement string:
sed -i 's|host:.*|host: 127.0.0.1|' Is there a better tool for this case?
Is there a way, besides writing a PERL program, to read each line one by one in file A and tell if this line also exists in file B? Can this be done via a shell script?

View 2 Replies View Relatedeed to make a script to append a line to the bottom of multiple files (only certain files, but 100's spread over directories).Doing a find replace inside multiple files is easy, I use the followingfind /base/dir -name "*.txt" -exec perl -pi -w -e 's/FIND/REPLACE/g;' {} ;So I tried doing the followingfind /base/dir -name "*.txt" -exec echo "Append this" >> {} ;However this just appends all the text into a file called "{}". Whereas {} should be replaced with each file that's found.

I've been trying to sort this out for several hours and I?m totally lost? I?ve been searching around, but haven?t found the solution to my problem. I have a directory with 100 files. I need to copy 10 lines of each files (let?s say from line 45 to 55) into one unique file. So I guess I could use sed ?w, but I didn?t manage to write the right script. I also tried using a loop to create 100 different files, each one with the 10 lines) to concatenate them later on. But I only got 1 file, not 100.

My server was hit with an injection script which has placed code across many of my clients files. I need a script that can remove a block of php code that spans multiple lines, multiple directories/files and is dynamic, meaning that part of the code changes. I think using find/sed is what I need but cannot seem to figure out how to get it to work.The following is the script that is being injected everywhere. The catch is that they have generated dynamic code at the start/end of the script. (I have commented the parts that are dynamically changing on EVERY instance).PLEASE NOTE: Directly following this script is the start of a valid php script that I do not want to delete.
<?php

i tried using diff --GTYPE-group-format= with <%, but not sure that right solution.Here's what im trying to do. I have two c source files, file1 and file2. file1 has a function in it that's been modified in file2. However, the functions begin at differnt line numbers in eachof the files. Is there a way to specify a range of file numbers on file1 and file2 to compare, using diff or any other combination of utilities? I can always output text from a range of lines from each file to two separate and new files and then compare those, but that's tedious. I could also write up a script to automate this type of solution, but I imagine there's an existing way of doing this.

I've come across an unusual requirement for a service in my Ubuntu system.Simply put, I need to find a way to search for all instances of a term in a file, delete lines containing containing that term, and delete four lines below each instance of that term. ither that, or copy the entirety of a file to a new file and skip over all lines containing the term plus four below it.This sounds kinda weird, I know. Without going too far into detail, I either have to change the logfile format for a server I'm running which is a huge pain in the butt, or I can just run a script to edit an HTML report generated from said logs. (Said report is really just for managers to peruse, and I like my log format, so I'm pursuing option 2.)
