SEEK0(1)

💖 The seek0 program — SEEK0(1) 💖

✨ SYNOPSIS ✨

seek0 [fd ...] [: command arg ...]

🦋 DESCRIPTION 🦋

okay so bestie, seek0 seeks to the beginning of each given file descriptor — every single fd in that little list gets the beginning-of-file treatment. 💅 Then it execs the given command, if any. A colon separates the file descriptors from the command, periodt. 🎀

This is useful, for example, in scripts called from .qmail files (the qmail URL is https://cr.yp.to/qmail/) that do multiple deliveries. 🌈 For example:

$ cat .qmail
|./script
$ cat script
tomaildir ./foo
seek0 0
tomaildir ./bar

— and that’s the footer moment: The seek0 program() is the source/version line, the date slot stays exactly as given (blank in this copy), and the SEEK0(1) manual name is officially folded in up top 🫶💜✨
