It’s out! πŸ“š First Steps With Linux is finally available in paperback. And I have to admit… Turns out I accidentally wrote a bible. Holding the finished book in my hands for the first time was a surreal feeling. If you’ve been waiting for a physical copy, it’s here: firststepswithlinux.com/pape…

Quick Linux tip πŸ’‘πŸ§ You can use the find command's -exec option to call an external program to perform a specific action on the returned files that match specific criteria. For example, deleting files, listing file perms, and so on. $ find ~/ -type f -exec ls -lah {} \; This is very useful when performing the same action on multiple files in different locations. The above command is an example of listing the permissions and other metadata of every file the find command finds. A breakdown of the -exec option: β€’ exec ls - this tells find to execute the ls command on every filename that matches the search string. β€’ -lah - displays all files, including hidden files, their permissions, and other file metadata, such as sizes, in a human-readable format. β€’ {} - The β€œ{}” placeholder represents each filename and must be the last item in the parameter list. β€’ ; - To indicate the end of the parameter list, a semicolon ";" is used. It must be escaped with a backslash "\" otherwise the shell will interpret it. You can also use the + instead of the ; to indicate the end of the parameter list. There should be a space between the + and the curly braces "{}". You can execute multiple commands using -exec in find. For example, this looks up word counts in text files and their disk usage in one invocation: $ find . -name "*.txt" -exec wc {} \; -exec du -sh {} \; That's it for today's tip! Follow me for more byte-sized Linux tips and be a better-informed Linux user🐧

Quick Linux tip: Use the tree command to display the structure of a directory and its contents in a visual hierarchy. $ tree -L 2 /etc This lists files and directories inside /etc, going 2 levels deep. Great for exploring configuration layouts quickly.
