Useful tools
- backup with relative path and checksum
- DATE=$(date +%F-%HH%M) && tar -C /home/user/path/data/ -cvf ~/place/to/share/backup.${DATE}.tar . && md5sum ~/place/to/share/backup.${DATE}.tar > ~/place/to/share/backup.${DATE}.tar.md5
- this should be put within a script and in crontab
Scripting
Warning, this section is really shell specific (i.e. bash != zsh ...)
- this does that
- this other command is nice
Check my ~/backups/*.sh and ~/bin/*.sh for examples
Bash
- $((do some math))
- echo $(( $(cat file | sed "s/.*\d//" | wc -l) * 1024))
Awk
- awk '{print $2}'
- grep action=edit page_generated.txt | awk '{ SUM += $2} END {print SUM}'
Distributions
Debian
- http://packages.qa.debian.org/w/win32-loader.html
- parameters to load an ISO file
- Debian Backports
- recompiled packages from testing (mostly) and unstable (in a few cases only, e.g. security updates), so they will run without new libraries (wherever it is possible) on a stable Debian distribution.
- installing from source
- apt-get update
- apt-get install build-essential
- apt-get -b source package
- dpkg -i package_versionnumber_arch.deb
- updatedb
- locate package | more
- cat /etc/debian_version

Note
My notes on Tools gather what I know or want to know. Consequently they are not and will never be complete references. For this, official manuals and online communities provide much better answers.
