sed command with -i option failing on Mac, but works on Linux
Command Line Magic: Fixing the sed -i Command on Mac 🧙♀️💻
So you've been using the powerful sed command on Linux to search and replace text, but when you tried it on your Mac, it blew up in your face? Fear not, my fellow tech sorcerer! We are about to uncover the mystery behind this "command-c expects \ followed by text" error and guide you through the incantations needed to make it work on your mystical Mac OS X. Let's dive in! 🌊
Unveiling the Culprit 🤔
First things first, let's understand the root cause of this issue. 🕵️♂️ The sed command you've been using is tailored for Linux and its GNU flavor. However, your Mac OS X uses a different flavor of sed, known as BSD sed, which has a slightly different syntax. This is why the same command that worked on Linux fails to cast its magic on your Mac. Now, let's get down to business and find a solution! ⚡️
Introducing the BSD sed Equivalent ➰
Fear not, brave soul, for there is a way to achieve the same results with BSD sed. 💪 Instead of using the -i option directly, we will take advantage of its alternative syntax. On BSD sed, you need to specify the backup file extension as an argument to the -i option. Let me show you an example: 🌟
Original Linux command:
sed -i 's/old_link/new_link/g' *Equivalent BSD sed command:
sed -i '' 's/old_link/new_link/g' *Notice that we provided an empty string '' as the backup file extension. This ensures that no backup file is created by BSD sed, mimicking the behavior of the Linux version. With this BSD-friendly command in your arsenal, you can now cast your spells with confidence! 🧙♂️✨
Simplifying the Process with a Handy Alias 🎩✨
Crafting the BSD sed command every time you need to perform a search/replace can be a hassle. But fear not, for there is another trick up our sleeves! We can create a convenient alias in your shell configuration file (.bashrc, .zshrc, etc.). Let's use the example command to illustrate the process: 🪄
alias sedi="sed -i ''"With this alias, you can now use a shorter command, sedi, instead of typing the whole sed -i '' incantation every time. Just like that, efficiency gets a little boost, and we have more time for our magical endeavors! ⏱🔮
