   1 Functions to deal with errors in bash
   2
   3 errcatch: set a trap on error to do bash-trace and exit
   4 errallow: undo errcatch
   5 errexit: exit and print stack trace
   6 bash-trace: print stack trace (best bash stack trace ever)
   7
   8 the err* functions depend on bash-trace.
   9
  10 For scripts without any nested function calls, this is usually sufficient:
  11 set -eE -o pipefail
  12 trap 'echo "$0:$LINENO:error: \"$BASH_COMMAND\" returned $?" >&2' ERR
  13
  14 Cleanup commands or functions can be appended to the ERR trap after a
  15 semicolon within the single quotes.
