pg (Unix)

pg is a terminal pager program on Unix and Unix-like systems for viewing text files. It can also be used to page through the output of a command via a pipe. pg uses an interface similar to vi, but commands are different.[1]

Example output of the pg command in xterm.

As of 2018, pg has been removed[2] from the POSIX specification, but is still included in util-linux. Users are expected to use other paging programs, such as more, less or most.

History

pg is the name of the historical utility on BSD UNIX systems. It was written to address the limit of the historical more command not being able to traverse the input backward. Eventually that ability was added also to more, so both are quite similar.

gollark: That is mildly accursed but cool.
gollark: Do most redstone computers even have central clock things? I don't think they can, the delay on redstone wires is really high.
gollark: No, they run on logic gates like in real ones, the underlying principles are very different.
gollark: Electricity does not run on remotely similar laws to redstone.
