PROJECT: 1) establish baseline of spreadsheets, documents and powerpoints that will be kept up to date across computers 2) determine naming convention of files 3) establish bi-directional ssh connections 4) develop a wrapper script to backup files after use and place them in an rsync'd directory 5) create a cronjob to rsync with all computers 6) manually examine updated files that were rync'd, determine if newer file is present, identify the differences, update primary LINUX LESSON: question: http://linuxmeister.net/Notes/PID-PPID-SID-processes-overview.html A) tree to list files and setup directory http://linuxmeister.net/Notes/tree-setup-suse.html B) file naming tricks to date and archive ls -l | grep -v ^d | sort | awk '{print "mv "$9" "$8"_"$6"_"$7"_"$9}' | \ sed -e s'$..:..$2014$g' | sed -e s'$2015_Dec$2014_Dec$g' > cleanup.files.sh.txt C) wrapper script for editing cp file file-date-before vi file cp file file-date-after D) SSH setup http://linuxmeister.net/Notes/SSH-setup-and-details.html E) Rsync overview http://linuxmeister.net/Notes/RSYNC-cmd.html F) crontab setup ------------------------------------------------ --> tree If 'tree' is not a typo you can use command-not-found to lookup the package that contains it, like this: cnf tree ------------------------------------------------ --> cnf tree The program 'tree' can be found in the following package: * tree [ path: /usr/bin/tree, repository: zypp (repo-oss) ] Try installing with: sudo zypper install tree --> sudo zypper install tree Loading repository data...
