# Shell script for seeing what the exim processes are doing. It gets rid
23
# of the old process log, then sends SIGUSR1 to all exim processes to get
24
# them to write their state to the log. Then it displays the contents of
27
# The following lines are generated from Exim's configuration file when
28
# this source is built into a script, but you can subsequently edit them
29
# without rebuilding things, as long are you are careful not to overwrite
30
# the script in the next Exim rebuild/install. However, it's best to
31
# arrange your build-time configuration file to get the correct values.
33
# Some operating systems have a command that finds processes that match
34
