Ever struggled to remember the exact capitalization of a file name or command in your terminal? We've all been there! But fear not, there's a way to make your life easier: case-insensitive completion. This nifty feature allows your terminal to suggest completions regardless of case. Here's how to enable it on macOS and Linux for the #bash shell: 1. Edit inputrc file with command below: 𝐞𝐜𝐡𝐨 '𝐬𝐞𝐭 𝐜𝐨𝐦𝐩𝐥𝐞𝐭𝐢𝐨𝐧-𝐢𝐠𝐧𝐨𝐫𝐞-𝐜𝐚𝐬𝐞 𝐨𝐧' >> ~/.𝐢𝐧𝐩𝐮𝐭𝐫𝐜 2. Save the file and restart your terminal. 𝑵𝒐𝒕𝒆: You can edit the system-wide inputrc file by replacing ~/.𝘪𝘯𝘱𝘶𝘵𝘳𝘤 to /𝘦𝘵𝘤/𝘪𝘯𝘱𝘶𝘵𝘳𝘤 with sudo. However, this method affects all users on the system. Proceed with care if using a shared machine. Now go forth and conquer the command line with case-insensitive ease! What is your favorite binary tool that you used to most in your Terminal? Let me know in the comment 💬
