• Machine comparison

 logfile=fx-mac-1.9-slave1
 set > $logfile
 # create a sha1sum for every file on the path
 echo >> $logfile; echo PATH: >> $logfile; (dirs=`echo $PATH | sed 's/:/ /g'`; for dir in $dirs; do if [[ '.' != $dir ]]; then find $dir -maxdepth 1 ! -type d | perl -nle 'system("openssl","dgst","-sha1",$_)'; fi; done) 2>&1 | tee -a $logfile
 # for Windows, sha1sum every file on INCLUDE
 echo >> $logfile; echo INCLUDE: >> $logfile; (dirs=`echo $INCLUDE | sed 's/;/ /g'`; for dir in $dirs; do if [[ '.' != $dir ]]; then find $dir -maxdepth 1 ! -type d | perl -nle 'system("openssl","dgst","-sha1",$_)'; fi; done) 2>&1 | tee -a $logfile

• Remove SeaMonkey nightly l10n builds (cltbld@stage)

cd /pub/mozilla.org/seamonkey/nightly/2008/
find 06 -type f ! -name '*en-US*' -ls | grep trunk | grep -v xpi | awk '{sum+=$7; printf("%9s   %s\n",$7,$11)} END{ print sum/1024/1024," MB to be saved"}' | tee ~/cf/remove_seamonkey_l10n/2008-06 | less
find 06 -type f ! -name '*en-US*' | grep trunk | grep -v xpi | xargs rm -v | tee -a ~/cf/remove_seamonkey_l10n/2008-06

• Remove old complete mar files (root@stage)

cd /pub/mozilla.org/firefox/nightly/2008/
find 01 -name '*complete.mar' -ls | grep -E '(mozilla1.8.0|mozilla1.8|trunk|mozilla1.9.0|mozilla-central|(action|trace)monkey)/' | awk '{sum+=$7; printf("%9s   %s\n",$7,$11)} END{ print sum/1024/1024," MB to be saved"}' | tee ~cltbld/cf/remove_mars/fx-2008-01
find 01 -name '*complete.mar'     | grep -E '(mozilla1.8.0|mozilla1.8|trunk|mozilla1.9.0|mozilla-central|(action|trace)monkey)/' | xargs rm -v | tee -a ~cltbld/cf/remove_mars/fx-2008-01

• Change account for CVS/Root

for i in `find . -name '*Root'`; do echo $i; in=`cat $i`; echo $in | sed s/cltbld/tbirdbld/ > $i; done

• Compress old log files (eg buildbot masters)

find . -mtime +5 -type f -size +10k -exec bzip2 -v {} \;

• on a buildbot master, figure out when jobs finished and who did them (win32 specific, need to put in build numbers into for argument)

for ((b=5013;b>=4990;b--)); do echo `ls -l $b`   `grep -a win32-slave $b | perl -nle '$_ =~ s/Building on: (moz2-win32-slave\d+)/$1/; print $1' | grep \.`; done
