Check These Out
That command installs "most" and make this command as the default man reader. The "most" works like "less" (the current man reader), but it render colors for manpages and may do more things. Read "man most".

The backtick operator, in general, will execute the text inside the backticks. On OS X, the pbpaste command will put the contents of the OS X clipboard to STDOUT. So if you put backticks around pbpaste, the text from the OS X clipboard is executed.
If you add the pipeline | pbcopy, the output from executing the command on the clipboard is placed back on the clipboard.
Note: make sure the clipboard is text only.
This will allow you to convert an audio file to wav format, and send it via ssh to a player on the other computer, which will open and play it there. Of course, substitute your information for the sound file and remote address
You do not have to use paplay on the remote end, as it is a PulseAudio thing. If the remote end uses ALSA, you should use aplay instead. If it uses OSS, you should berate them about having a lousy sound system. Also, you're not limited to transmitting encoded as wav either, it's just that AFAIK, most systems don't come with mp3 codecs, but will play wav files fine.
If you know SoX is installed on the remote end and has mp3 codecs, you can use the following instead:
$ cat Klaxon.mp3 |ssh thelab@company.com play -t mp3 -
this will transmit as mp3. Again, use your specific information. if you're not playing mp3s, use another type with the -t option
I tried out on my Mac, jot to generate sequence ( 0,25,50,..), you can use 'seq' if it is linux to generate numbers, need curl installed on the machine, then it rocks.

Find statistics for an Edirectory server form LDAPsearch.
We have a lot more examples at:
http://ldapwiki.willeke.com/wiki/Ldapsearch%20Examples
The full command got shut off it is:
ldapsearch -h ldapserver.willeke.com -p636 -e C:\mydata\treerootcert.der -b "" -s base -D cn=admin,ou=administration,dc=willeke,dc=com -w secretpwd "(objectclass=*)" chainings removeEntryOps referralsReturned listOps modifyRDNOps repUpdatesIn repUpdatesOut strongAuthBinds addEntryOps compareOps wholeSubtreeSearchOps modifyEntryOps searchOps errors simpleAuthBinds inOps oneLevelSearchOps inBytes abandonOps bindSecurityErrors securityErrors unAuthBinds outBytes extendedOps readOps dsaName directoryTreeName vendorVersion vendorName
For example, to remove line 5 from foo, type: vi +5d +wq foo
At some point you want to know what packets are flowing on your network. Use tcpdump for this. The man page is obtuse, to say the least, so here are some simple commands to get you started.
-n means show IP numbers and don't try to translate them to names.
-l means write a line as soon as it is ready.
-i eth0 means trace the packets flowing through the first ethernet interface.
src or dst w.x.y.z traces only packets going to or from IP address w.x.y.z.
port 80 traces only packets for HTTP.
proto udp traces only packets for UDP protocol.
Once you are happy with each option combine them with 'and' 'or' 'not' to get the effects you want.
Here's a bash version.
Find biggest files in a directory
This is helpful for shell scripts, I use it in my custom php install script to schedule to delete the build files in 3 hours, as the php install script is completely automated and is made to run slow.
Does require at, which some environments without crontab still do have.
You can add as many commands to the at you want. Here's how I delete them in case the script gets killed. (trapped)
atq |awk '{print $1}'|xargs -iJ atrm J &>/dev/null
