The bash builtinforiterates through arguments, while$(ls)splits the output oflsinto arguments wherever there arespaces,newlinesortabs. This means that you're iterating over words, not filenames. However, this can be problematic if you have filenames that contain words that match globs in ...
The “.” means “current directory” The-type fpart means “only search for files (not directories)” -execmeans “execute the following command” grep -l 'alvin'is the command that searches the files for the string “alvin” The{} \;part of the command is a little unusual ... I ...
For example, [[:alnum:]] means the character class of numbers and letters in the current locale. In the C locale and ASCII character set encoding, this is the same as [0-9A-Za-z]. (Note that the brackets in these class names are part of the symbolic names, and must be included i...
In order to utilize the feature in Linux, it is necessary to have the Linux operating system installed. Once the configuration is complete, inputting the user information will allow the user to log in and access all the operating system's built-in features with their username and password. T...
Digging into macros a little bit more and explore some of its internals. A macro will stop running in case it can't execute one of its commands. For example, iff((which meansfind(and position the cursor on top of it) can't be executed, then the macro replay will stop immediately. Yo...
The output of the function is, in general, a non-linearly spaced array of inputs (x) and their corresponding function values (f) that satisfy f = func(x). How does the function work? The bisect() function works recursively, which means the function calls itself until some criteria is ...
This means that if an array contains another array as one of its elements, the function will also apply the user-defined function to that nested array.How Does array_walk_recursive() Work?The array_walk_recursive() function takes two parameters: the array to be processed and the user-...
To me this means that most Linux systems are not affected, which might be interesting information for RH users. [1]: https://github.blog/2024-05-14-securing-git-addressing-5-new-vulnerabilities/#recursive-clones-on-case-insensitive-filesystems-that-support-symlinks-are-susceptible-to-remote-...
The /register page has a CSRF token that alters the page's response slightly with each new request (sometimes affecting overall length). This means that a simple line/word/char filter won't be able to filter all responses. In order to filter those redirects out, one could use a command ...
in the previous command. You can create a practically unlimited number of directories in this fashion all at once. As soon as they’re created, they function completely like any other directories. This means that if you try to remove the top one, it will complain about not being empty too...
