46 The feisty meow configuration is damaged somehow. Please change to the
47 directory where it is stored, e.g.:
49 cd /opt/feistymeow.org/feisty_meow
51 and run this command (the whole unwieldy thing on multiple lines):
53 echo pwd outside \$(pwd\) ;
54 exec bash -i 3<<EOF 4<&0 <&3
55 echo pwd inside is \$(pwd\);
56 export FEISTY_MEOW_APEX=\"\$(pwd)\";
57 export FEISTY_MEOW_APEX=\$FEISTY_MEOW_APEX;
58 export FEISTY_MEOW_SCRIPTS=\$FEISTY_MEOW_APEX/scripts;
59 /bin/bash \$FEISTY_MEOW_APEX/scripts/core/reconfigure_feisty_meow.sh;
60 source \$FEISTY_MEOW_APEX/scripts/core/launch_feisty_meow.sh;
64 Note that this assumes that the .bashrc file could still need editing to fix
65 an erroneous FEISTY_MEOW_APEX variable, so we skip it above when bash runs.
66 Check \$HOME/.bashrc to see if a change there will fix the problem.
