@marighost I dont use Prox, but for various random linux commands.. ive got a wealth. :D in the journalctl vein.

journalctl -xeu \<service name\>

ex: journalctl -xeu httpd

Gives you the specific journal output for the given service. In this example. httpd.

Also, journalctl is more than boot logs, its all of your logs from anything controlled by systemd. Mounts, services, timers, even sockets.

For example. On my system, i have /var/home as a mount. systemctl and journalctl can give me info on it with:

systemctl status var-home.mount
journalctl -xeu var-home.mount

You can see all of the mounts with.
systemctl list-units --type=mount

Or, see all of your services with
systemctl list-units --type=service

Or all of your timers with
systemctl list-timers

We do a weekly show on getting into linux terminals, commands, tricks, and share our experience.. It's called Into the Terminal. on the Red Hat Enterprise Linux youtube channel. I'll send you a link if you're interested.

Deleted comment.

I double posted as Mlem didn’t show my initial comment after posting for some reason.

(Edit)

Journalctl | grep -C 10 'foo' was useful for me when I needed to troubleshoot some fstab mount fuckery on boot.

Ha! Remember back when there was no fstab fuckery? Good times. But you have a massive init blob slowly eating other services and replacing them with shitty replicants like this embarrassment (ohai root NFS) and all of us Unix people are chuckling in our reduced-fuckery 'hell'.

Running Wine is the command I've used the most probs, you can tell I haven't touched the thing in months.

These aliases for zsh I use all the time. It's part of the prezto configuration framework.

setopt AUTO_CD              # Auto changes to a directory without typing cd.
setopt AUTO_PUSHD           # Push the old directory onto the stack on cd.
setopt PUSHD_IGNORE_DUPS    # Do not store duplicates in the stack.
setopt PUSHD_SILENT         # Do not print the directory stack after pushd or popd.
setopt PUSHD_TO_HOME        # Push to home directory when no argument is given.

alias d='dirs -v'
for index ({1..9}) alias "$index"="cd +${index}"; unset index

Type d and enter to list all the directories you've recently been in, then type the number at the start of the line followed by enter to immediately cd there.

Not sure if latest bash can do it the same thing, but some years ago I wrote a script to implement it there too. IIRC it might've been the automatic removal of duplicates in dir history that was missing.

Various uses of "find" in particular. "xargs" sometimes too. The capabilities of "bash" in general including scripting and the whole redirection, piping, and multiprocessing capabilities in particular.
