Laravel немного ускоряется при переходе с PHP 8.1 на 8.2. А с PHP 8.3 вы получаете еще плюс 38% производительности.

#bash #nano #linux

#bash #linux #debian #root #sudo

How to ignore sudo in commands on server (if only root user exists):

Problem:

root@mx1:~# sudo nano somefile.txt
-bash: sudo: command not found

nano /etc/bash.bashrc

Before:

if [ -x /usr/lib/command-not-found -o -x /usr/share/command-not-found/command-not-found ]; then
        function command_not_found_handle {
                # check because c-n-f could've been removed in the meantime
                if [ -x /usr/lib/command-not-found ]; then
                   /usr/lib/command-not-found -- "$1"
                   return $?
                elif [ -x /usr/share/command-not-found/command-not-found ]; then
                   /usr/share/command-not-found/command-not-found -- "$1" 
                   return $?
                else
                   printf "%s: command not found\n" "$1" >&2
                   return 127
                fi
        }
fi

After:

function command_not_found_handle {
        # check because c-n-f could've been removed in the meantime
        if [ -x /usr/lib/command-not-found ]; then
           /usr/lib/command-not-found -- "$1"
           return $?
        elif [ -x /usr/share/command-not-found/command-not-found ]; then
           /usr/share/command-not-found/command-not-found -- "$1"
           return $?
        else
           if [ "$EUID" -eq 0 ] && [[ $1 == sudo* ]]; then
              full_command="$0 $@"
              drop_sudo="${full_command#-}"
              drop_sudo="${drop_sudo#bash}"
              drop_sudo="${drop_sudo# }"
              drop_sudo="${drop_sudo#sudo}"
              drop_sudo="${drop_sudo# }"
              bash -c "$drop_sudo"
              return $?
           else
              printf "%s: command not found\n" "$1" >&2
           fi
           return 127
        fi
}
