# Determine current directory

# Determine absolute path to location from which we are running.
#   We must run from that location in order for tms_keycmd to find
#   its configuration files.
# Note that output is sent to /dev/null in the unlikely case that the cd command
#   generates extraneous output that would interfere with the surrounding $()
# The -P option on pwd is for better handling of symlinks.
# The "--"  on cd is in case the directory begins with "-". The "--"
#   tells the shell that there are no more options.

# Run the TMS KeyCmd program with all arguments passed on the command line.
# Note that "$@" is used so that original order and grouping is perserved.
#   For example, input arguments might look like this: "a b 'c d'"
# Note also that running the command directly does not work for some linux
#   distriubtions, for example rocky linux 8.10. Not clear why. Problem
#   apparently related to shell environment.
