cmd > file.txt
cmd >> file.txt
cmd < file.txt
cmd 2> file.txt
cmd > file.txt 2>&1
cmd1 | cmd2
cmd1 2>&1 | cmd2

three gotchas:

1. cmd file.txt > file.txt will delete the contents of file.txt

some people use set -o noclobber (in bash/zsh) to avoid this

But I just have "never read from and redirect to the same file" seared into my memory.

2. sudo echo blah > /root/file.txt doesn't write to /root/file.txt as root. Instead, do:

echo blah | sudo tee /root/file.txt

or

sudo sh -c 'echo blah > /root/file.txt'

3. cmd 2>&1 > file.txt doesn't write both stdout and stderr to file.txt. Instead, do:

cmd > file.txt 2>&1

panel 3: cat vs <

I almost always prefer to do:

cat file.txt | cmd

instead of

cmd < file.txt

it usually works fine & it feels better to me

using cat can be slower if it's a GIANT file though

panel 4: &> and &|

some shells support &> and &| to redirect/pipe both stdout and stderr

(also some shells use |& instead of &|)

Not all samurai during the Edo period (1603–1868) wore suits of armor. Some, like rōnin who were not in the employment of a lord or samurai police officials in the large cities like Edo, today’s Tokyo, wore chain mail (kusari) for protection. This is a matching set of chain mail jacket (kusari katabira) and gloves (kusari han kote). The linked chain is attached on layers of indigo dyed cloth, decorated with family crests in gold. The collar was once furnished with hexagon shaped iron plates (kikkō) that are now lost.

Picture of a group of lovely horses cloned from the same mare, and text reading

'Inside the pasture were seven clones of the same mare, all two years old or younger and being kept for a polo client. The chocolate-brown fillies looked so similar, it felt like a trick of the eye, although it was their behavior that caught me off guard. Instead of scattering around the meadow, they all grazed in a clump, and when they saw us walking through the pasture, they trotted over, moving in unison like a murmuration of starlings. Each one explored me in the same affable way as they took turns sniffing my sneakers, notebook, and hair. All seven trailed us back to the car.

'To many of ViaGen’s clients, cloning is appealing because of the potential they see to replicate an animal’s physical and mental makeup. ViaGen’s website assures customers that a clone can share the original’s temperament and intelligence. But some people have come to believe that clones get even more from the founder animal than that: They theorize that past experiences can be recorded in an organism’s cells through a process they refer to as “cellular memory,” and transmitted just like eye color. “There’s not a scientist in the world who will agree with me, except that I’ve seen it,” Veneklasen said.'
