    How to limit search result of directories/files to limited top-level directories only?

    I did a find / -name 'XXX' and the output is insane. It lists every file and the list never ends (I had to Ctrl-C to stop it). How can I view the results meaningfully? For example, I'd like to limit to the result to appear only for, say the top-level (or top 2nd or 3rd level) directories only...

    rc.d shell scripts: no extension vs. .sh

    I think I asked this question sometime ago, but I can't find the answer when searching for it. Anyway... First, I think I know the difference for startup shell scripts located in /etc/rc.d and /usr/local/etc/rc.d. The former is for system scripts while the latter is for user-installed scripts...

    Solved Shell Script IPC/RPC Messaging Between Different Hosts?

    I would like one of my hosts to broadcast occasional periodic signals to a shell script running on other host(s) on the same LAN. I'm currently reading about various IoT protocols, but I'm wondering what the more traditional approaches were for this kind of messaging. Ideally, I'd want some...

    Solved Correct syntax for the 'a' function of FreeBSD's sed?

    I'd liked to use the 'a' function of sed to append something after a given line in a file. For instance, I want to add "ListenAddress xx.xx.xxx.xxx" after the line that begins with "#ListenAddress" in a copy of sshd_config: Using sh I do: # IP=xx.xx.xxx.xxx # sed -E -i ""...

    jails How do I "setenv PATH" in a jail, preferably using zsh?

    If I execute the command: setenv PATH "/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:/root/bin:/root/.cargo/bin" after going into the jail by "jexec 1", it would work. However, I'd like to make it sticky. I tried many ways but nothing works. Further, preferably, I'd like to do...
