NAME¶
nst-msg - send message to nst terminal emulator
SYNOPSIS¶
nst-msg [-S] [-s] [-d] [-D] [-t] [--cwds]
DESCRIPTION¶
nst-msg is a tool to interact with running nst(1) terminal emulator instances.
Most commands target the currently running terminal which is identified by the NST_IPC_ADDR environment variable that is automatically set by nst. Some commands are global and target all terminal instances accessible by the calling user.
OPTIONS¶
-S, --snapshot
save snapshot of the current terminal history. The
snapshot can later be retrieved via -s.
-s, --get-snapshot
Print the data stored during the last snapshot operation
(-S) to stdout. If no snapshot is available then nothing is printed.
-d, --get-history
Print (dump) the current terminal history buffer to
stdout.
-D, --get-global-history
Like -d but prints the concatenated history of all
accessible nst instances to stdout. This can be used to search for data lost
in one of many terminal instances.
-t, --test
Performs a connection test to the associated nst terminal
emulator instance. If the connection succeeds then an exit status of zero is
returned, non-zero otherwise. This can be used to determine whether an nst
terminal is associated at all.
--cwds
This retrieves the current working directories of the
child processes of all reachable nst instances. One CWD is printed per line,
and only unique entries are printed. This does not currently support the
exotic case that the CWD may contain a newline character.
--version
Print the nst-msg version number and exists.
-h, --help
Print a usage text.
