What's the easiest way to search for a string in a text file in GNOME or on the console? I used to do this in kfindfile back on KDE.I'd like to avoid downloading something like desktop search if at all possible because I'm away for the holidays and stuck on a dialup connection.
View 5 RepliesI have a file called Regions.ini that looks like this:
Code:
[Granite]
RegionUUID = 54ab7cd2-0e70-49b7-8020-8dbeb84c08d0
Location = 9991,10007
InternalAddress = 0.0.0.0
InternalPort = 9001
AllowAlternatePorts = False
ExternalHostName = 71.171.21.9

RegionUUID = 8fc56fdd-0afd-4074-9432-0ae8f42b799f
Location = 9992,10007
InternalAddress = 0.0.0.0
InternalPort = 9000
AllowAlternatePorts = False
ExternalHostName = 71.171.21.9
What I need to do is find out what the IP address is after "ExternalHostName ="
After that I will need to compare that IP to whatismyip and if it's different then replace it but that is easy to do with sed. I just can't figure this simple hurdle out.
im tryin to make a tool in visual C++ which will take an input string through a text box,then it will compare tht string with a text file containing data and display the matched results in list box.

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.

I mean, this string should be removed from each line and save in another file.
Im trying to read a file in c++ and search for particular character for example if this is a list that I have:
Alice
Bob
David
[code]....
if the input is D, it should give David, if its B, gives bob. so in this case, meaning it reads the first character of every line. but if possible I want to make this dynamic so the user can specify which character position he is looking for, so in case he is looking for R as character index 3 in all lines, it should give Charlie. but the problem is, it does now recognize , besides, I do not know how to specify the character position in each line.
here is my code
Code:
#include <iostream>

I'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?
View 3 Replies View RelatedI put a text file on my desktop and added a couple lines of text with gedit. File type shows text/plain. Double-click opens the file in gedit which is what I want. I'm using the file to temporarily hold some snips of code that I copy from file to file, but when I copy some html into the file and save it, now file properties show it's text/html and a double-click opens the file in firefox, which isn't what I want. Is there some way to keep the file type from changing itself?
View 6 Replies View RelatedI am having trouble writing a script that monitors a text file. When the file contains number 1 (or any other string that is not a command) it does nothing, but when it is something different from 1, it executes that command.
So, there are 2 files: monitor.mon - this is the file that will be checked constanlty; and test.sh - the script that does the job. The monitor.mon file will have its content modified by php. This means a web page will have a form where I input commands and writes does commands in the file. Test.sh will watch when the file's content changes from character 1 to a command, execute that command and write back a 1 so it will not execute it more times.
I tried combining while and if but with no success. Tried reading the file with cat and grep -e but it doesn't seem to recognize when content changes.
I have large text files with space delimited strings (2-5). The strings can contain "'" or "-". I'd like to replace say the second space with a pipe. What's the best way to go?
Using sed I was thinking of this:
sed -r 's/(^[a-z'-]+ [a-z'-]+) /1|/' filename.txt
write such script (bash script). I have some text file with name filename.txt I must check if this file contains string "test-string-first", I must cut from this file string which follows string "keyword-string:" and till first white-space and save it to some variable.
For example. File: PHP Code: PHP Code:

As indicated in the subject, I want to search a text. If the text is present I want to replace it. But if the text is not present, I want to insert it after first line and before last line.
Searched text is:CleanCache "*";
Where * can be anything.
Example: CleanCache "false"; -> CleanCache "true";
If CleanCache "false"; is not present, only insert CleanCache "true"; after first line and before last line.

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:

Does anyone know of a way to perform a search for multiple file extensions at once in Gnome? I know that M$ Windows Explorer had this capability, but I'm just not sure how to do it in Gnome, or if it's possible. I just want to be able to perform searches for Video, Music, and Document file types, without having to perform a separate search for each file extension. Example: When doing a search for Video file types (.avi,.mp4,.mov,.wma, etc.), I would like to do one search for all files that have these file extensions, instead of doing one search for .avi files, a second search for .mp4 files, another for .mov files, etc.
View 8 Replies View RelatedI have tracker installed, and when I use "tracker-search ..." from terminal, I can find files as expected. In particular, it searches within file contents, not just the titles.
I was hoping to have similar functionality directly from gnome-shell. I've found a number of extensions to do this such as: [URL] .... but none of them work (gnome 3.14, debian Jessie).
How to set up file contents search directly from gnome in Jessie?
