Don't do it with bash.

Perl is everywhere (AFSPerl)

     http://www.mpa-garching.mpg.de/kwiki/nog/afsperl/

Python is most everywhere (yours truly):

     http://ats.sourceforge.net/

For Example:

"""
     Quota-committal-based version of 'vos partinfo'

     This tool displays output similar to the output of 'vos partinfo'
     but instead of showing 'K free' on a partition, it shows the number
     of K uncommitted quota-wise.  That is, when volumes are created,
     they are assigned a quota, and as such, that space should be 
technically
     marked as unavailable space, even if the volume is not full of data.
     This tool will show you how much space is "truly" free for your
     committal to a new or different volume on the same partition.

     if syslogflag:
         qpidata.printSyslogReport(verboseflag)
     else:
         qpidata.printReport(verboseflag)
else:
     print "ERROR: Could not load/gather data."
     sys.exit(1)
