# tee
|
|
|
|
> Read from `stdin` and write to `stdout` and files (or commands).

|
|
|
|
- Copy `stdin` to each file, and also to `stdout`:
|
|
|
|
`echo "example" | tee {{path/to/file}}`
|
|
|
|
- Append to the given files, do not overwrite:
|
|
|
|
`echo "example" | tee {{[-a|--append]}} {{path/to/file}}`
|
|
|
|
- Print `stdin` to the terminal, and also pipe it into another program for further processing:
|
|
|
|
`echo "example" | tee {{/dev/tty}} | {{xargs printf "[%s]"}}`
|
|
|
|
- Create a directory called "example", count the number of characters in "example", and write "example" to the terminal:
|
|
|
|
`echo "example" | tee >(xargs mkdir) >(wc {{[-c|--bytes]}})`
