Recursive behavior in Linux commands involves executing an operation on a directory and all of its subdirectories and files. For example, using the -r
or --recursive
option with commands like cp
, rm
, or chmod
allows these commands to apply the specified action not just to the target directory but also to all its contents recursively. This is particularly useful for managing large directory trees efficiently. However, it should be used with caution, especially with destructive commands like rm
, to avoid unintentional data loss.
In order to zip a subdirectory in Linux you would use the zip command with the recursive flag to specify that it should add all files under that directory into the zip file. The command would then be zip -r .zip .
k is not a standard command in Linux.
There is no such command. Obviously, in order to enter a command into the prompt, Linux must already be on.
In a Linux terminal, the command to create a new directory is: mkdir .
In Linux the chmod command is used to set file permissions.
Nothing. Helo is not a recognized command in linux.
The accronym "GNU" stands for Gnu Is not Unix. Technically speaking, it's "GNU/Linux" because Linux is the kernel, not the whole thing, we just shorten it to Linux (I do this myself, but I do know that Linux is just the kernel). It is made up of the Linux kernel and several GNU programs (try typing a basic command into a terminal with --help, chances are you could easily find one that says GNU somewhere at the bottom).
Linux does not have a limit as to the number of characters you can enter in a command.
You get a command not found. Linux is case sensitive. So, for example: The command "systemctl" will not be the same as "SystemCTL" to a shell in Linux. One will work, the other will return an error saying there's no such command.
