1) Problem with stripping front & back slashes
Looking for an easy way to find php array definitions without quotes
$foo[bar] = 'bad';
with definitions with quotes:
$foo['bar'] = 'good';
Peter Bojanic suggested the following:
grep \"[[^'\"$].*[^'\"]]\" *.php
Which is the set of all things in square brackets that do not start with either quote character or a $. This set includes some valid extras, like $bits[count($bits)-1], but you just have to careful.
Extra spaces below a ?> in a php script can cause problems with cookies, caching, sessions, etc.. It's often a problem finding which file has the extra spaces. However the following find commands (written by Peter Bojanic & David O'Neill):
find . -name *.php -o -name *.class -o -name *.inc | xargs -n 1 perl -0777ne 'print $ARGV,\"n\" if !(/?>$s) && !(?>[r]$s)'
If you're not worried about trailing white space, then the following version can narrow the results down a bit bit more:
find . -name *.php -o -name *.class -o -name *.inc | xargs -n 1 perl -0777ne 'print $ARGV,\"n\" if !(?>[ t]*$s) && !(?>[ t]*[r]$/s)' 2) Finding recently mofidifed files This is a useful way to find recently modified files: find /file/path/ -mtime -30 -type f
