I’ve been setting up a new Proxmox server and messing around with VMs, and wanted to know what kind of useful commands I’m missing out on. Bonus points for a little explainer. Journalctl | grep -C 10 'foo' was useful for me when I needed to troubleshoot some fstab mount fuckery on boot. It pipes Journalctl (boot logs) into grep to find ‘foo’, and prints 10 lines before and after each instance of ‘foo’.

I use $_ a lot, it allows you to use the last parameter of the previous command in your current command mkdir something && cd $_ nano file chmod +x $_ As a simple example. If you want to create nested folders, you can do it in one go by adding -p to mkdir mkdir -p bunch/of/nested/folders Good explanation here: koenwoortman.com/…/q Sometimes starting a service takes a while and you’re sitting there waiting for the terminal to be available again. Just add --no-block to systemctl and it will do it on the background without keeping the terminal occupied. systemctl start --no-block myservice

Is there a version of $_ that works with mv? It just keeps renaming my files to “filedir,” I’m trying sort through a directory and move some files to another for keeping, be easier if I could do: mv picture1.jpg /path/to/keepdirectory then do something like mv picture2.jpg $_ And so on. But with that I’d just be renaming all my photos “filedir” instead of moving them lol.

I just tried your use case, and it did move the files to the correct folder. using zsh: user@computer  ~  touch test.jpg user@computer  ~  touch test2.jpg user@computer  ~  mv test.jpg ./Public user@computer  ~  mv test2.jpg $_ user@computer  ~  ls ./Public test2.jpg test.jpg user@computer  ~  using bash: [user@computer Public]$ mkdir test [user@computer Public]$ ls test test2.jpg test.jpg [user@computer Public]$ mv test.jpg ./test [user@computer Public]$ mv test2.jpg $_ [user@computer Public]$ ls test [user@computer Public]$ ls test/ test2.jpg test.jpg [user@computer Public]$ using bash and full path: [user@computer Public]$ ls test test2.jpg test.jpg [user@computer Public]$ mv test.jpg /home/user/Public/test [user@computer Public]$ mv test2.jpg $_ [user@computer Public]$ ls test [user@computer Public]$ ls test/ test2.jpg test.jpg [user@computer Public]$ What shell are you using? You can check it by using echo $0. user@computer  ~  echo $0 /usr/bin/zsh [user@computer ~]$ echo $0 /bin/bash I can’t reproduce it, even when putting the directory path in quotes, it still simply moved the file.
