General :: Search For Text Strings In Multiple PHP Files?
Feb 3, 2011Long story short, I got a folder with nearly 800,000 php files. I would like to search each file for a string and if it exists in that file, the file gets copied to another directory. Is this possible from the terminal? So far I got: grep -i -n -r 'ppr-1792' * | cp $1 move_to_here
But this obviously doesn't work. $1 needs to be the file name that contains matching text.
Programming :: Write A Utility Which Will Scan In A Text File And Search And Replace Strings?
Jul 16, 2010Something very handy to do in a Linux shell, is manipulating files and strings - essentially parsing data. Write a utility which will scan in a text file and search and replace strings. We also want to keep track of how many strings we've replaced.
I know that my command would look like this: <utility name> <filename> <stringToSearchFor> <stringToReplaceWith>
Code: #!/bin/bash

CentOS 5 :: Search A Text File For The Existence Of Certain Strings And Execute A Command If They Exist, Something Along The Lines?
Feb 23, 2010This 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.
General :: Sed Search To Match NOT Several Strings?
Nov 15, 2010I am using sed to process an ascii tcpdump file whereby each packet is processed into a line with the same number of columns and useful information is pulled out like the time, packet type, length, and also IP addresses, payload type and port numbers where appropriate. The time is already changed to seconds, followed by the protocol over ethernet, such as IP, IP6, ARP etc. and I can change anything it detects as IP, IP6 and ARP into some other string, pulling out necessary information depending on the protocol and payload.The beginning part of the search for IP starts with the sed search /([0-9][0-9]*.[0-9][0-9]*)[ ]IP[ ,] ... /, where time is in seconds and ellipses means more stuff, and likewise for IP6 and ARP.But how do I process the lines that are NOT IP, IP6 or ARP? (Specifically NOT /IP[ ,]/, /IP6[ ,]/ or /ARP[ ,]/.) So that I can format them into a string with the same number of columns.

Jan 29, 2010Is there a faster way to search for a file containing a given string than using grep -re "string" /
This takes a long time to search through the entire system, so I was wondering if there is a faster way. I don't know the name of the file, just that it will contain a given string.
General :: Retrieve The Text Difference Between Two Strings Having Substrings?
May 10, 2011I got requirement to find the difference between two strings and write the difference to new file by comparing the substrings separted by commas
Below mentioned is an example of requirement
String1 --> ABC,DEF,GHI,JKL
String2 --> MNO,ABC,XYZ,DEF
In String1 and String2 the substrings are separted by commas. The substrings which are common between String1 and String2 are ABC,DEF this common substrings has to be written to a file say common.txt ( having the text ABC,DEF). And the substrings GHI,JKL in String1 which are not present in String2 has to be written to another file say String1Extra.txt (having the text GHI,JKL). In the same way the substrings MNO,XYZ from String2 which are not present in String1 has to be written to another file say String2Extras.txt(having the text MNO,XYZ) .

General :: Using Grep / Awk To Search For Colored Text

The command's output has a range of colours signifying too many different things to specify using text, with colour being the only form of grouping.

General :: Search For Exact Repetitions In Text File
Nov 23, 2010I've got a big text file in which I know have probably made some typos (LaTeX). Sometimes I rewrite sentences several times and then end up with double pieces like "the the" or "is is" without noticing it. Most spell checkers that I can use in LaTeX are very basic so they do not notice these grammar errors. Is there a way that I can search for these repetitions by hand using sed or awk or something along these lines? Is there an app for that?

Apr 25, 2011I am trying to construct a quick regex that will search for six lines of text without a clear line break between them. It only needs to search, not replace, as I will be using in gEdit (with regex plugin) anyway.
It's for editing subtitle files. The video player I will be using them on can only cope with 3-line subtitles, so I just need to edit any in the srt file that contain four or more. There won't be many so I can do it manually. For example:

but .* seems to mean "any character, or none", so that doesn't work. My experience of regular expressions is limited, but I do know they are very powerful when used correctly!
