Linux in a Nutshell, 6th Edition

q

Synopsis

[address]q
[address]q [value]{G}

Quit when address is encountered. The addressed line is first written to the output (if default output is not suppressed), along with any text appended to it by previous a or r commands. GNU sed allows you to provide value, which is used as the exit status.

Examples

Delete everything after the addressed line:

/Garbled text follows:/q

Print only the first 50 lines of a file:
