a few linux commands i have hanging around.. collecting

linux-command-cheatsheet.sh

# find only files and chmod
# because I never remember the syntax
find . -type f -exec sudo chmod 664 {} \;

# untar .tar.gz
tar xvzf file.tar.gz

# untar .tar.bz2
tar xjvf file.tar.b

# to compress as .tar.gz
tar czf filename.tar.gz /path/to/folder

# find/replace í mörgum skrám.. fengið að láni (og útskýrt) frá:
#  - http://rushi.wordpress.com/2008/08/05/find-replace-across-multiple-files-in-linux/
find . -name "*.php" -print | xargs sed -i 's/foo/bar/g'

# bara finna í mörgum skrám og birta línunúmer:
find . -name "*.php" -exec grep -Hin 'strengur' {} \;
