"Even though I've been using Linux for decades and am perfectly at home with the command line, I often tell those who are thinking about trying the open-source operating system that it isn't necessary. It's not. Truly. If I wanted to, I could give up the command line altogether. Of course, I'd have to find GUI apps to replace some of the commands I use, but it can be done."
"I regularly have to SSH into remote systems to take care of certain things. Yes, I realize that means I'm still using commands (on the remote machine), so my argument that you can go without touching the terminal kind of ends there. But those are special cases that new Linux users won't have to worry about (i.e., administering a remote server). SSH is one of those commands I use every day, throughout the day."
Command-line use is optional but many tasks are more efficient with core tools. SSH enables daily remote access and administration that GUI tools often cannot replace. chmod sets executable permissions for scripts, allowing ./filename execution after chmod u+x filename. Essential commands cover networking, troubleshooting, and file viewing while remaining simple enough for new users to learn. Some workflows can be replaced by GUI apps, but remote server administration and script automation typically require command-line proficiency. Examples include ssh jack@192.168.1.11 for remote login and chmod u+x filename to make a script executable.
