I have a txt file with couple of comment lines:
Number of title = !num!
#line1
#line2
#line3
I wrote a script with "sed" to replace !num! in this file, which is very straightforward. However, based on the !num!, I want to remove the number of "#" based on the !num! value. Is there an easy way to do that with "sed"; otherwise, i will have to write a script to loop through the file.
I want to be able to remove the first character of a line when I highlight multiple lines in gedit. Example:
%Example is
%Commented Code
%Uncomment using this shortcut
I would then highlight/select these lines, and remove the first character to make it look like this:
Example is
Commented Code
Uncomment using this shortcut
I'm pretty sure there is an actual shortcut for this. If there is another text editor on Linux that it would work in, it would be nice to know how to do it in that editor as well.
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!!

eed 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.
