I have a script that among other things generates a makefile with an error that causes make to fail. specifically, the string "-Wimplicit-function-dec" should be changed a bit to "-Wimplicit-function-declaration". Is there a way to have bash add the new eight characters in the right place (on line 105)?
View 2 RepliesI 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.

View 5 Replies View RelatedI have a very large data file, with 3 numbers in each line, ex. 3 4 5 ; 6 7 8.I want to add two numbers (0 and 1) at the end of every line, and a string at the beginning of the line. Does anyone know a efficient way to do so?

How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.
If I have a word in a text file and I need to replace it by another word (for example, i need to replace abc by fff) so what is the command I can type it?

I have an idea to install a video-camera to record 24/7 the place in the yard where the car will be kept. Can not say that I'll configure such a system for sure, but I have an interest to it. On the other hand I've never worked with such systems and I don't know what cameras are better, should they be IP-based or the USB-webcam will be OK, I also do not know much about the software. I've found that gphoto is a good software for such a purppose, and some photo-cameras can be managed remotely through console, I mean that we can take pictures/?video?
Remotely, if the camera is connected to the Linix-box via USB. Another soft, which I googled, which (as I understood) is de-facto and which is powerful, is ZoneMinder. Today a friend of mine told me that many IP-cameras have everything inside them (a webserver, many tools for capturing video/photo and so on), so I just need to create some directory on the PC, where it will store all photos/videos. So, as you see, I know practically nothing about all this. That's why I decided to listen to you, what software and photo/video cameras would you recommend me.
How do i delete a specific string in vi? Suppose i want to delete only the instance "ing" occuring in a file through vi , how could i do this??
View 3 Replies View RelatedThese must a be a question you received a lot, but I couldn't find a similar thread! It's a simple question.
I need to delete a specific string from a file. For example the specific numbers "3456" from a file. I've tried with the tr comand, using
Code:
tr -d '3456' file,
but it also deleted whichever ocurrence of 3,4,5,6 from my file. Should I use a regular expression?
I have a line in a text file that has 40 random characters within a tag and i want to change the characters to a new set of 40 random characters (alphanumeric a-z 0-9 etc)

How would i go about doing that?
Also second question same as the above but how would i remove them instead of replacing them?
How can you remove files containing a specific string?I have...Code:find |grep 'string'This may return several results and I wanted to rm the results.I also have...Code:ls -l |grep 'string'|awk '{print $9}'which also may return results.But point is, I can't supply the results as a parameter to rmI was thinking of looping but I don't know how to access the results as if they were an array or something.

I thought this would be relatively easy but I have not been able to find out how to do it, unless I'm looking to far into a simple problem. Do i have to put the string into a file, and sign the file, or can i just sign the string/message?

I am a member of a group which has written a program whose source code is being held in a specific directory (~cs252/Assignments/basicAsst/project) and we want to go through and change the parameters for the function "sequentialInsert." My job is to find all occurances of the function call to "sequentialInsert" and to also list the files from where the code came from. Also, I have to be in the commandsAsst directory when I do this. I have tried grep and find combined together, and I am at a lost.
View 1 Replies View RelatedWhat i want to do is pretty simple.I want to uncomment every line that begins with "deb" (except for deb cdrom) in /etc/apt/sources.list.I know how to do this through system > administration > software sources.I know I can gksu gedit /etc/apt/sources.list.I'd rather not do it that way.I'd rather have a script do it. It's less work, less typing, less clicking, and would work the same on every ubuntu version.
