Search through files, ignoring .svn

By putting the "-not $ -name .svn -prune $" in the very front of the "find" command, you eliminate the .svn directories in your find command itself. No need to grep them out. You can even create an alias for this command: alias svn_find="find . -not $ -name .svn -prune $" Now you can do things like svn_find -mtime -3
This is sample output - yours may be different.
8

find . -not $ -name .svn -prune $ -type f -print0 | xargs --null grep <searchTerm>

Find out which debian package a command (executable) belongs to on debian-based distros

This revision to my command (command #8851) was called for when it failed to find the parent package of 'rlogin', which is really a deep symbolic link to /usr/bin/ssh. This revision fixes this newfound issue, while ensuring fixes of other older issues work too. Show Sample Output

a find and replace within text-based files, to locate and rewrite text en mass.

syntax follows regular command line expression. example: let's say you have a directory (with subdirs) that has say 4000 .php files. All of these files were made via script, but uh-oh, there was a typo! if the typo is "let's go jome!" but you meant it to say "let's go home!" find . -name "*.php" | xargs perl -pi -e "s/let\'s\ go\ jome\!/let\'s\ go\ home\!/g" all better :) multiline: find . -name "*.php" | xargs perl -p0777i -e 's/knownline1\nknownline2/replaced/m' indescriminate line replace: find ./ -name '*.php' | xargs perl -pi -e 's/\".*$\"/\new\ line\ content/g' Show Sample Output

Monitor logs in Linux using Tail

Works in Ubuntu, I hope it will work on all Linux machines. For Unixes, tail should be capable of handling more than one file with '-f' option. This command line simply take log files which are text files, and not ending with a number, and it will continuously monitor those files. Putting one alias in .profile will be more useful.
This is sample output - yours may be different.

restore the contents of a deleted file for which a descriptor is still available

Note that the file at the given path will have the contents of the (still) deleted file, but it is a new file with a new node number; in other words, this restores the data, but it does not actually "undelete" the old file. I posted a function declaration encapsulating this functionality to http://www.reddit.com/r/programming/comments/7yx6f/how_to_undelete_any_open_deleted_file_in_linux/c07sqwe (please excuse the crap formatting).

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Retrieve the size of a file on a server

Downloads the entire file, but http servers don't always provide the optional 'Content-Length:' header, and ftp/gopher/dict/etc servers don't provide a filesize header at all.

Catch a proccess from a user and strace it.

It sits there in a loop waiting for a proccess from that user to spawn. When it does it will attach strace to it

Mac Sleep Timer

Schedule your Mac to sleep at any future time. Also wake, poweron, shutdown, wakeorpoweron. Or repeating with $ sudo pmset repeat wakeorpoweron MTWRFSU 7:00:00 Query with $ pmset -g sched Lots more at http://www.macenterprise.org/articles/powermanagementandschedulingviathecommandline

Mutt - Change mail sender.

Grabs the complete module list from CPAN, pulls the first column, ditches html lines, counts, ditches small namespaces.

urldecode with AWK

Fast and simple awk urldecoder! Note: Parameter -n is specific to GNU awk

Prevent non-root users from logging in

Also with optional message: $ echo "no login for you" > /etc/nologin (This doesn't affect your current X session - you're already logged in!)

ls not pattern

I've been looking for a way to do this for a while, get a not pattern for shell globs. This works, I'm using to grab logs from a remote server via scp.
