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 RepliesI know how to use grep to output a line that matches a string. But what if I also want to output one line above every line containing a matching string, how do I do that?

View 4 Replies View RelatedHow 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.
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.

Example:

childfile1.txt 2000 lines.
childfile2.txt 1000 lines.
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
//{{65281980 - DYNAMIC!!

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.

View 3 Replies View RelatedI have two text files in the form:1 ItemA [value]2 ItemB [value]3 ItemC [value]Some of these items are common for both files, while others are missing from either one or the other.I want to compare the values for each common item in the two lists, but don't know how. I have a vague idea that probably grep might be useful, but I don't know how to use it for this purpose.So, to sum it up, what I would like to do is to take to text files containing lists and merge their common items into a third file in the form:
1 ItemA [value_from_list1] [value_from_list2]
2 ItemB [value_from_list1] [value_from_list2]
3 ItemC [value_from_list1] [value_from_list2]

I have a situation where a directory has about 1.5 million files in it. On an hourly basis, I want to be able to find any files that have changed in the last hour, compress them, encrypt them and then copy them to both a local backup machine and an off site backup.
Is there any kind of utility or kernel module that creates some type of log of modified files? I know I can use find, but the search for -mtime in this directory takes quite a while and will not suffice for an hourly backup.
To find all files recursively starting with a . (period), is the following OK:
find ./ -name '.'*
i am a newbie in linux ,i am writing a bash script to identify the files which are exactly 7 days ( a week old) i tried this command find /var/backup -mtime +7 -exec ls -d {} ;but this gives me even the files which are older than 7 days

I am looking for this `struct messages_sdd_t` and I need to search through a lot of *.c files to find it.However, I can't seen to find a match as I want to exclude all the words 'struct' and 'messages_sdd_t'. As I want to search on this only 'struct messages_sdd_t' The reason for this is, as struct is used many times and I keep getting pages or search results.The directory I am searching in, has another directories so it will have to search recursively.I have been doing this without success:Code: find . -type f -name '*.c' | xargs grep 'struct messages_sdd_t'and thisCode: find . -type f -name '*.c' | xargs egrep -w 'struct|messages_sdd_t'
