commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. 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.

First-time OpenID users will be automatically assigned a username which can be changed after signing in.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):

Analyze an Apache access log for the time period with most activity and display the hit count, requesting IP and the timestamp. May help detect a brute force dos attack.
cut can handle files as well. No neet for a cat.
Same as the rest, but handle IPv6 short IPs. Also, sort in the order that you're probably looking for.
The first sort is necessary for ips in a list to be actually unique.
The wajig package is not installed by default.
Show's per IP of how many requests they did to the Apache webserver
Compares the md5 checksums of the contents of two directories, outputting the checksum and filename where any files differ. Shows only the file name, not the full path.
Compute the md5 checksums for the contents of two mirrored directories, then sort and diff the results. If everything matches, nothing is returned. Otherwise, any checksums which do not match, or which exist in one tree but not the other, are returned. As you might imagine, the output is useful only if no errors are found, because only the checksums, not filenames, are returned. I hope to address this, or that someone else will!
bit of a contrived example and playing to my OCD but nice for quick scripted output of listening ports which is sorted by port, ip address and protocol.
Goes through all files in the directory specified, uses `stat` to print out last modification time, then sorts numerically in reverse, then uses cut to remove the modified epoch timestamp and finally head to only output the last 10 modified files.
Note that on a Mac `stat` won't work like this, you'll need to use either:
find . -type f -print0 | xargs -0 stat -f '%m%t%Sm %12z %N' | sort -nr | cut -f2- | head
or alternatively do a `brew install coreutils` and then replace `stat` with `gstat` in the original command.
The other commands were good, but they included packages that were installed and then removed.
This command only shows packages that are currently installed, sorts smallest to largest, and formats the sizes to be human readable.
bash-3.2$ find /logs -ls -xdev | sort -nrk 7 | head -10

This command is useful for finding out which directories below the current location use the most space. It is summarised by directory and excludes mounted filesystems. Finally it is sorted by size.
dumpfile is a CSV file, which its 1st field is a phone number in format CC+10 digits
Empty lines are deleted, before the output in format "prefix,ocurrences"
If you have a directory with lot of backups (full backups I mean), when it gets to some size, you could want to empty some space. With this command you'll remove half of the files. The command assumes that your backup files starts with YYYYMMDD or that they go some alphabetical order.
perhaps you should use CMD[$2] instead of CMD[$4]
Counts of messages by recipient, with frozen messages excluded.
I don't like doing a massive sort on all the directory names just to get a small set of them. the above shows a sorted list of all directories over 1GB. use head as well if you want.
du's "-x" flag limits this to one file system. That's mostly useful when you run it on "/" but don't want "/proc" and "/dev" and so forth. Remember though that it will also exclude "/home" or "/var" if those are separate partitions.
the "-a" option is often useful too, for listing large files as well as large directories. Might be slower.
list the top 15 folders by decreasing size in MB
