HEREDOC(1)

🌸 HEREDOC(1) 🌸

okay so welcome to the heredoc man page bestie, this is the General Commands Manual entry and it's literally the cutest little glue tool in execline, i promise 🫶

✨ NAME ✨

heredoc — run a command with a certain string fed to a file descriptor 💅

✨ SYNOPSIS ✨

heredoc [-d] fd string prog...

✨ DESCRIPTION ✨

so here's the vibe: heredoc exec(3)s into prog..., and it makes string available on the fd file descriptor. that's it. that's the whole thing. main character energy honestly 👑

one very important thing tho — string must not contain a null character 💀 like, for real, don't do it.

heredoc is meant to be used in place of the shell << construct, which includes here-documents into scripts. so if you've been out here writing << in your scripts and feeling some type of way about it, this is your girlie 🌈

✨ OPTIONS ✨

• -d — Run the process feeding string to fd as a grandchild of heredoc. the whole point of this is to prevent a zombie from hanging around if prog... has read string and fails to wait for its children 🧟‍♀️ no cap, zombies are not the vibe.
