21 # this script cannot handle figuring out where it lives, so approaches that
22 # get the THISDIR will fail. this is a consequence of this always being used
23 # in bash's 'source' directive, which does not pass the script name as
24 # argument 0. instead, we just check for the bad condition of a malconfigured
25 # script system and try to repair it.
27 # we start out thinking things are good.

44 The feisty meow configuration is damaged somehow. Please change to the
45 directory where it is stored, e.g.:
47 cd /opt/feistymeow.org/feisty_meow
49 and run this command (the whole unwieldy multiple line chunk inside the bars):
53 exec bash -i 3<<EOF 4<&0 <&3
54 echo -e '\n\n^^^ errors above here indicate potential problems in .bashrc ^^^';
55 export FEISTY_MEOW_APEX=\"\$(pwd)\"; export FEISTY_MEOW_SCRIPTS=\$FEISTY_MEOW_APEX/scripts;
56 export FEISTY_MEOW_SHOW_LAUNCH_GREETING=yes;
57 /bin/bash \$(pwd)/scripts/core/reconfigure_feisty_meow.sh;
58 source \$(pwd)/scripts/core/launch_feisty_meow.sh; exec 3>&- <&4
63 This code snippet assumes that the .bashrc file could still need editing to
64 fix an erroneous FEISTY_MEOW_APEX variable, so we skip it above when bash
65 runs. Check \$HOME/.bashrc to see if a change there will fix the problem.
