Jeg har en schell skript som kjøres kontinuerlig på et AIX-system. Det er faktisk startet fra et annet shell script med "ksh-x" kommando og så jeg bare skrive utdataene til en loggfil. Dette fører til at loggfilene til å bli fylt med stort sett unyttig informasjon. Jeg ønsker å endre dette skriptet til å skape sin egen loggfil internt og kunne bare ha det stokk velger acitivity. Skriptet ser slik ut:

is_file_arrived() {
   [ -z "$1" ] && return 1
   local file=$1
   local arrived=1
   local size1 size2
   if [ -f "$file" -a -z "$(fuser $file 2> /dev/null)" ] ; then
      size1=$(ls -l $file 2>/dev/null | awk '{print $5}')
      sleep ${IFA_WAIT:-15}
      size2=$(ls -l $file 2>/dev/null | awk '{print $5}')
      [ ${size1:-1} -eq ${size2:-2} ] && arrived=0
   fi
   return $arrived
}

   local fileName=$1
   local fileExtension=$2

   mv -Eignore $fileName $fileNewName     
   prepup $fileNewName $fileExtension
   mv -Eignore  $filePrintPath/$fileODIName $fileTmpPath/$fileODIName
   save2tmp $fileExtension
   call_siu $fileExtension   ###I'd like to add when this command is run and the $fileExtension given date/time

do
   for fileName in /gers/nurev/datafiles/[Uu][Pp][Ll][Oo][Aa][Dd].[0-9][0-9][0-9
][0-9]     ###I'd like to log when a file is found with date/time
   do
      fileExtension=${fileName#*.}
      is_file_arrived "$fileName" && nsec=1 && processFile $fileName $fileExtens
ion
   done
   sleep $nsec
   case $nsec in
      1)   nsec=15;;
      15)  nsec=45;;
      45)  nsec=90;;
      90)  nsec=300;;

Du kan gjøre noe som dette:

LOG() {
   echo "$*" >> $LOG_DIR/$LOG_FILE
}

LOG "0002 processed at 11-11-06/12:00)"

LOG() {
   echo "$(date +%c) $*" >> $LOG_DIR/$LOG_FILE
}

Jeg endte opp med noe lignende med:
