## SCRIPT: 01_anyfile4Dir_start_Xterminal_here_withMultiCmds_xterm.sh
##
## PURPOSE: This script opens an xterm with the shell environment
##          'positioned' at the current' directory  ---
##          and executes a user-specified 'string' of commands ---
##          and only those commands. (There is no command prompt for further
##          command entry.)
##
## METHOD:  This script uses zenity to prompt for the command(s),
##          with examples shown.
##
##          'xterm' is run with the '-hold' parameter, to see error messages
##          if the command fails with a syntax error or whatever.
##
##          Since the '-e' option of xterm accepts only one command (with
##          optional parameters), this script uses a separate, hidden (Nautilus)
##          script, '.eval_cmds4term.sh', in the scripts directory with
##          this script, to pass the (multi-)command string to 'xterm'
##          for execution.
##
## HOW TO USE: In the Nautilus file manager, right-click on ANY file
##             (or directory) in the desired 'here' directory.
##             Then select this script to run (name above).
