cat a b b | sort | uniq -u > c # c is set difference a - b

- Use `grep . *` to visually examine all contents of all files in a directory. Useful for directories filled with config settings, like /sys /proc /etc.

||||
```sh
|
||||
cd /proc/sys/net/ipv4
|
||||
grep . *
|

```

- Summing all numbers in the third column of a text file (this is probably 3X faster and 3X less code than equivalent Python):
|
||||
```sh
|
||||
awk '{ x += $3 } END { print x }' myfile
