@ -379,6 +379,8 @@ A few examples of piecing together commands:
- `split `and `csplit`: splitting files
- `sponge`: read all input to memory before wriring it, useful for reading from then writing to the same file (for example, `grep -v something some-file | sponge some-file`)
- `units`: unit conversions and calculations; converts furlongs per fortnight to twips per blink (see also `/usr/share/units/definitions.units`)
- `7z`: high-ratio file compression
