💖 NAME 💖

tee — read from standard input and write to standard output and files 🫶

(also hi bestie, this is tee(1) from the User Commands section of the manual, she's iconic, let's go 💅)

✨ SYNOPSIS ✨

tee [OPTION]... [FILE]...

🎀 DESCRIPTION 🎀

Okay so the whole vibe: tee copies standard input to each FILE, and ALSO to standard output. Yes bestie, both at once, that's literally her whole thing, she's a splitter, a divider, a duplicator of streams. 🌈

✨ OPTIONS ✨

  • -a, --append — append to the given FILEs, do not overwrite. (write-over is cancelled, we're adding to the end now 🎀)
  • -i, --ignore-interrupts — ignore interrupt signals 😤
  • -p — operate in a more appropriate MODE with pipes
  • --output-error[=MODE] — set behavior on write error. See MODE below 👇
  • --help — display this help and exit
  • --version — output version information and exit

MODE determines behavior with write errors on the outputs:

  • warn — diagnose errors writing to any output
  • warn-nopipe — diagnose errors writing to any output not a pipe
  • exit — exit on error writing to any output
  • exit-nopipe — exit on error writing to any output not a pipe
The default MODE for the -p option is 'warn-nopipe'. With "nopipe" MODEs, exit immediately if all outputs become broken pipes. The default operation when --output-error is not specified, is to exit immediately on error writing to a pipe, and diagnose errors writing to non pipe outputs. 📢 no cap, that's the whole rule, memorise it bestie
