pushln

pushln [arg ...]

pushln is a zsh builtin that pushes its arguments (concatenated with spaces) onto the shell's buffer stack. The buffer stack is a LIFO (last-in, first-out) data structure. Entries on the buffer stack are presented as editor buffer content for the next interactive command line, or can be read programmatically with getln.This is equivalent to print -nz (push onto the editing buffer stack without a trailing newline). The buffer stack provides a way to pre-fill the command line or pass data between shell functions.

Only available in zsh. The buffer stack is cleared when the shell exits. In interactive use, pushed lines appear as editable input at the next prompt. Arguments are concatenated with spaces (like print -nz), not pushed as separate stack entries.

pushln is part of zsh's buffer stack mechanism, introduced as a complement to getln for the Z Shell's unique line buffering system.
