This works: $ find . -name “*.php” -exec chmod 755 {} \; -exec /bin/echo {} \; | wc -l You have to include a second -exec /bin/echo for this to work. If the find command has no output, then wc has no input to count lines for.
explainshell helpfully explains your command, and gives an excerpt from man grep: -w, –word-regexp Select only those lines containing matches that form whole words. So just remove -w since that explicitly does what you don’t want: grep -rn ‘/path/to/somewhere/’ -e “pattern”
This is a little different from Banthar’s solution, but it will work with versions of find that don’t support -newermt and it shows how to use the xargs command, which is a very useful tool. You can use the find command to locate files “of a certain age”. This will find all files modified between … Read more
Remove the space: $(“div.a[customattrib=’2′]”) By putting in the space, you’re making it into a descendant selector which finds all elements that match [customattrib=’2′] and are inside an element that matches div.a.
Yes, you can: irb(main):002:0> s1 = “foo” #=> “foo” irb(main):003:0> s2 = ObjectSpace._id2ref(s1.object_id) #=> “foo” irb(main):004:0> s2.object_id == s1.object_id #=> true irb(main):005:0> s2[0] = “z” #=> “z” irb(main):006:0> s1 #=> “zoo” Should you do this? I’ll leave that up to you. There are less geeky ways to store an object with a serializable id (e.g. … Read more
find . -name ‘*.class’ -printf ‘%h\n’ | sort -u From man find: -printf format %h Leading directories of file’s name (all but the last element). If the file name contains no slashes (since it is in the current directory) the %h specifier expands to “.”.
It might be better to use find for this: find . -name “pattern_*” -printf ‘.’ | wc -m In your specific case: find . -maxdepth 1 -name “20061101-20131101_kh5x7tte9n_2010_*” -printf ‘.’ | wc -m find will return a list of files matching the criteria. -maxdepth 1 will make the search to be done just in the … Read more
You need to include the interests table. @events = Event.all(:include => :interests, :conditions => [“interests.id = ?”, 4]) You had it right in your post, but you didn’t pluralize interests. Update Because this answer is still getting attention, I thought it might be a good idea to update it using ActiveRecord::Relation syntax since the above … Read more
Use the .IndexOf() method of the list. Specs for the method can be found on MSDN.
The manual page tells you that -o is the OR operator. If you want case insensitivity, use iname instead of name. find /path/to/folder -iname “*.bin” -o -iname “*.sh”
