Linux scripts : boincstats

I wrote many bash, php and perl scripts for my haartsen.nl server (Fedora Core 6) and backup server (Fedora 14), which I would like to share. They are often not the most optimal scripts in terms of code or processing efficiency, but hey, they work :-). Most scripts are created because I could not find a similar script on the Internet.

Name: boincstats
Description: A script to show the current status of running BOINC tasks

#!/bin/bash
#
# boincstats    Shows the current status of running BOINC tasks
#
# Author:       Peter Haartsen <peter@haartsen.nl>
#

# Set SLOTSDIR to the directory where your BOINC slots are located (without trailing slash)
# Typical locations are "/usr/local/BOINC/slots" or "/var/lib/boinc/slots"

SLOTSDIR="/var/lib/boinc/slots"

# No modifications needed below this line

echo -e "CPU Time\tProgress\tRemaining\tTask"

for PROC in `ls -1d $SLOTSDIR/*/ | xargs -l basename`
do

  RESULTNAME=`grep result_name $SLOTSDIR/$PROC/boinc_task_state.xml | tr -d '    ' | sed 's/^<.*>\([^<].*\)<.*>$/\1/'`
  CPUTIME=`printf "%.0f" $(grep checkpoint_cpu_time $SLOTSDIR/$PROC/boinc_task_state.xml | tr -d '    ' | sed 's/^<.*>\([^<].*\)<.*>$/\1/')`
  ELAPSEDTIME=`printf "%.0f" $(grep checkpoint_elapsed_time $SLOTSDIR/$PROC/boinc_task_state.xml | tr -d '    ' | sed 's/^<.*>\([^<].*\)<.*>$/\1/')`
  PROGRESS=$(echo "`grep fraction_done $SLOTSDIR/$PROC/boinc_task_state.xml | tr -d '    ' | sed 's/^<.*>\([^<].*\)<.*>$/\1/'` * 100" | bc)

  REMAINING=`printf "%.0f" $(echo "scale=10;$ELAPSEDTIME * ( 100 / $PROGRESS - 1 )" | bc)`

  printf "%02d:%02d:%02d\t" $((CPUTIME/3600)) $((CPUTIME/60%60)) $((CPUTIME%60))
  printf "%7.2f%%\t" $PROGRESS
  printf "%02d:%02d:%02d\t" $((REMAINING/3600)) $((REMAINING/60%60)) $((REMAINING%60))
  echo $RESULTNAME

done

Example output:
