*nix Tips & Tricks frequently forgotten..

*nix tips and code snippets i seem to always for get syntax for:

tar -pczf name_of_your_archive.tar.gz /path/to/directory
tar -zxvf name_of_archive.tar.gz
tar -tvf filename.tar or tar -ztvf filename.tar.gz (to list contents)
rm -f /path/and/folder/to/remove
rm -r /path/and/folder/to/removeeven/if/full
cp -arv folder/* ../path_to_overwrite_to_move_subfolders
at job example: at -f /data/home/www/html/atjob 12:58 10/06/2009 (runs the atjob file, at the specified location, at the specified time) at -l (lists currently scheduled jobs)
download an entire site using wget:
- wget --mirror –w 2 –p --HTML-extension –-convert-links –P /path/to/folder/example1 http://www.yourdomain.com
- a nicer version of the above command, may be: wget --wait=20 --limit-rate=20K -r -p -U Mozilla http://www.internets.com/
to unzip all archives in a folder (in bash): "for i in *.tar.gz; do echo working on $i; tar xvzf $i ; done"
Best bash prompt:
export PROMPT_COMMAND='PS1="\[\033[0;33m\][\!]\`if [[ \$? = "0" ]]; then echo "\\[\\033[32m\\]"; else echo "\\[\\033[31m\\]"; fi\`[\u.\h: \`if [[ `pwd|wc -c|tr -d " "` > 18 ]]; then echo "\\W"; else echo "\\w"; fi\`]\$\[\033[0m\] "; echo -ne "\033]0;`hostname -s`:`pwd`\007"'
