Handy ways to avoid set -e -x (execute, vexecute, die, log, elog, stderr)

BASH_script.sh

#!/bin/bash

set -u ;

log=$(basename "$0" | sed -e 's/[.][^.]*$//') ;
elog="$log.stderr.log" ;
log="$log.stdout.log" ;

die() { echo $1 ; exit 1 ;
}
cd $(dirname $0) || die "ERROR: Failed to cd $(dirname $0): $? ." ;
thisD=$(pwd) ;
elog="$thisD/$elog" ;
log="$thisD/$log" ;
_ex() {
  "$@" || die "ERROR: execute: $@: $?" ;
}
_vex() {
  echo "$@" ;
  "$@" || die "ERROR: vexecute: $@: $?" ;
  echo ;
}
execute() { ( _ex "$@" 2>&1 ) >> $elog
}
vexecute() { ( _vex "$@" 2>&1 ) >> $elog
}
