alt0() { o=$(bash -c '#!/usr/bin/env bash

{
   l_output="" l_output2="" l_perm_mask="0137"
   l_maxperm="$( printf '"'"'%o'"'"' $(( 0777 & ~$l_perm_mask )) )"
   while IFS= read -r -d $'"'"'\0'"'"' l_fname; do
      l_mode=$(stat -Lc '"'"'%#a'"'"' "$l_fname")
      if [ $(( "$l_mode" & "$l_perm_mask" )) -gt 0 ]; then
         l_output2="$l_output2\n - file: \"$l_fname\" is mode: \"$l_mode\" (should be mode: \"$l_maxperm\" or more restrictive)"
      fi
   done < <(find /etc/audit/ -type f \( -name "*.conf" -o -name '"'"'*.rules'"'"' \) -print0)
   if [ -z "$l_output2" ]; then
      echo -e "\n- Audit Result:\n  ** PASS **\n - All audit configuration files are mode: \"$l_maxperm\" or more restrictive"
   else
      echo -e "\n- Audit Result:\n  ** FAIL **\n$l_output2"
   fi
}' 2>&1); printf '%s\n' "$o" | grep -q '\*\* PASS \*\*' || { echo "step1: script did not report PASS"; return 1; }; }; if alt0; then echo compliant; fi

Sortie attendue: compliant
