[Solved]I might have mis-configured something now my PKGBUILD use this vim like editor? I don't even have vim installed, it only print out plain text in the terminal before, how can I revert it back?
I could be mistaken, but that editor looks like nano, which is just a super simple text editor. Ctrl-x should bring quit the editor and ask if you want to save.
How were you editing PKGBUILD files before? A GUI based editor?
It could be nano but I had to press Q to exit which is not nano key binding (Ctrl + X), I never edit PKGBUILD in terminal before, I'll edit it in Kate if I had to
Dude you're a time saver, it's actually less a text editor I never heard of before after I removed it PKGBUILD revert back to what it was before, it probably come with man page package I installed recently
Less is not an editor, it's a "pager" which is a read-only viewer for files, or for command output that doesn't fit in a single screen, or whatever. Generally to control which you want programs use you set the PAGER environment variable.
The old grandaddy pager was called "more", as in "there's more text than fits on the screen". The successor is called "less". For most purposes, less is more.
Another way to fix this, would have been to navigate to the pkgbuild file in question, right click, open with, Kate. I’m more familiar with Gnome than KDE but I assume there’s an option to make Kate your default for opening files of that type.
