You can therefore easily create a wrapper script that processes the current and last accounting files by default but otherwise acts like regular qacct. This means a bare qacct command won't show no history just after a logrotate.
#!/bin/bash
exec ${SGE_ROOT}/bin/${SGE_ARCH}/qacct -f <(cat
${SGE_ROOT}/${SGE_CELL:-default}/accounting.1
${SGE_ROOT}/${SGE_CELL:-default}/accounting) "$@"
NB: If you are backing up the logfiles then you may find, depending on how
smart your backup software is, that using the dateext option
will save some strain on incremental/differential backups. If you do use
dateext then finding the immediately previous accounting file will require
a bit more smarts than the above.
