  • That’s horrible for muscle memory, every time I switch desk/keyboard I have to re-learn the position of the home/end/delete/PgUp/PgDn keys.

    I got used to Ctrl-a / Ctrl-e and it became second nature, my hands don’t have to fish for extra keys, to the point that it becomes annoying when a program does not support that. Some map Ctrl-a to “Select all” so, for input fields where the selection is one line, I’d rather Ctrl-a then left/right to go to the beginning/end than fish for home/end, wherever they are.


  • That quote was in the context of simply separating values with newlines (and the list also included “your language’s split or lines function”).

    Technically you don’t even need awk/sed/fzf, just a loop in bash doing read would allow you to parse the input one line at a time.

    while read line; do 
       echo $line # or whatever other operation
    done < whateverfile
    

    Also, those manpages are a lot less complex than the documentation for C# or Nushell (or bash itself), although maybe working with C#/nushell/bash is “easy when you’re already intuitively familiar with them”. I think the point was precisely the fact that doing that is easy in many different contexts because it’s a relatively simple way to separate values.


  • For the record, you mention “the limitations of the number of inodes in Unix-like systems”, but this is not a limit in Unix, but a limit in filesystem formats (which also extends to Windows and other systems).

    So it depends more on what the filesystem is rather than the OS. A FAT32 partition can only hold 65,535 files (2^16), but both ext4 and NTFS can have up to 4,294,967,295 (2^32). If using Btrfs then it jumps to 18,446,744,073,709,551,615 (2^64).





  • What do you mean by “not require sudo privileges”?

    Do you mean not require root permissions? that depends on what are you trying to do. You’ll need to make changes in your system to allow normal users to have permissions for it, and in many cases that’s not possible (or very safe).

    If what you mean is that you don’t want to need to type"sudo" every time, but still be able to have the commands run with root permissions, then there’s multiple ways to do this:

    • Add an alias such as alias command='sudo command'. If you don’t want to type the password, you can change the sudores file so that your user doesn’t need to enter a password when running sudo for that command (someone else in the comments already explained how to do that, using an entry with NOPASSWD: /usr/bin/command in the sudoers config).

    • alternatively: set the SUID bit of the executable you want to run, so that every time the file is executed (by anyone) it will always execute as the user who owns the file (so if the owner is root, the file will always be executed as root)… this is not something I’d recommend though, since it can lead to security vulnerabilities.
