Haven't used PV. I do use watch a bit.

Because of this thread I've been conditioning myself to use glances. It really is very useful.

Glad to hear someone else like it!

@johnhooks So, you just use

pv dd if=/dev/urandom of=/dev/sda bs=512k

That's actually really handy.

pv dd if=/dev/urandom of=/dev/sda bs=512k

YOu have to pipe it in, it's a strange syntax

dd if=/dev/zero | pv | dd of=/dev/sda

Also any flags or arguments go before the first pipe.

[scottalanmiller]

Very odd indeed.

That is a bit odd. Still handy tho.

Sample output.

[Lakshmana]

My favourite linux command is "ls"
"cd"

I use those quite a bit also.

I use them all the time, doesn't mean I like them. At least ls is shorter than dir.

[stacksofplates]

This is also helpful, diff is confusing unless you use some flags.

diff -y -W 70 file file2

It makes viewing changes much easier. Below is a screenshot. The pipe shows there is a difference in the line, and the < or > show that there is a line added or subtracted.

I always end up typing dir on my linux machines and ls on my windows machines.... it just frustrates me...

[Nic]

Back in the day, one of my faves was "rn"

[RamblingBiped]

@brianlittlejohn Switch to powershell and always use "ls"

This thread deserves more attention than it gets. I was getting annoyed with dd and no status display today (lots of Raspberry Pis to image.) This time I know the exact size of the sd cards being imaged tho, so pv is very helpful.

dd if=/home/comtech/rpi.img | pv -s 16g | dd of=/dev/mmcblk0 bs=4k

[root@localhost comtech]# dd if=/home/comtech/rpi.img | pv -s 16g | dd of=/dev/mmcblk0

This isn't installed by default on some systems, but i easy & quick to add.

[dbeato]

Mine has been grep and cat.

When I want to use virt-manager from my Mac.

ssh -Y username@ip-address
