HTP (HTTP Time Protocol) is an alternative way of getting "good enough" synchronized time. htpdate will give you near-second accuracy. It works where NTP/SNTP does not because of firewalls and proxies. Of course, if NTP/SNTP can be used, use that instead. http://www.clevervest.com/twiki/bin/view/HTP htp is not in Ubuntu!

OMG, you are a Gentoo junkie. -funroll-loops-me-harder ;-) http://ccache.samba.org/ ccache is a compiler cache, which speeds up your compiler on successive runs, because it caches intermediate compiled output. Show Sample Output

I sometimes want to know what packages are installed on my Ubuntu system. I still haven't figured out how to use aptitude effectively, so this is the next best thing. This allows finding by name. The grep '^ii' limits the display to only installed packages. If this is not specified, then it includes listing of non-installed packages as well. Show Sample Output

Given a GNU Make file version 3.81 with the following entries: .PHONY: runtest runtest: $(ARCHNAME) $(TESTAUTOEXES) @for i in $(TESTAUTOEXES) ; do \ echo ">>>> Running test harness $$i" ; \ env $(RUNTESTENV) $$i ; done .PHONY: runtestsingle runtestsingle: $(ARCHNAME)/test/auto_$(testsingle).exe $(ARCHNAME) @for i in $< ; do \ echo ">>>> Running test harness $$i" ; \ env $(RUNTESTENV) $$i ; done (ARCHNAME is something like ix86-linux-gnu) Instead of typing gmake runtest to run all the tests, you can run one specific test with the example command. The sample output is from compiling a C++ program using Boost::Test testing framework. Show Sample Output

I can remember "cp -av" on Unix like systems to copy files and directories. The same can be done on Windows without extra software, somewhat. The switches mean: /E Copies directories and subdirectories, including empty ones. Same as /S /E. May be used to modify /T. /H Copies hidden and system files also. /Y Suppresses prompting to confirm you want to overwrite an existing destination file. /Z Copies networked files in restartable mode. /I If destination does not exist and copying more than one file, assumes that destination must be a directory. /K Copies attributes. Normal Xcopy will reset read-only attributes. /F Displays full source and destination file names while copying. I don't type that all the time, I stick it into a file called "cpav.cmd" and run that. echo xcopy /e/h/y /z/i /k /f %1 %2 > cpav.cmd cpav zsh zsh2 http://support.microsoft.com/kb/323007 Show Sample Output

dd for windows is available from http://www.chrysocome.net/dd Tested with CD-ROMs like Linux install discs I don't know about DVD-ROMs.

In the Windows cmd.exe window, you can change the directory using cd, but if you need to go to a directory on another drive, you need to type in the drive letter and colon first (e.g. d:). With the /d on cd, you don't need this intermediate step. cd /? Tested on Windows XP Show Sample Output

Sometimes I want to use the mouse to move/copy/delete files. (I also sometimes feel like a nut, sometimes I don't.) This is for Windows 2000 and later, probably. Tested on Windows XP, cmd.exe. http://support.microsoft.com/kb/130510 Show Sample Output

This works in bash and zsh. You may also want to alias it, if you need to look at it often... alias lpath="echo \$PATH | tr : \\\\n" "\$PATH" to make sure to look at your current $PATH Show Sample Output

On Windows 2000 or later, this command will give a listing of all the registered Windows services. You can then know what the name of a command is in order to start and stop it. e.g. sc start Apache2.2 or net start Apache2.2 Please note that sc will allow the SERVICE_NAME only, while net will allow both SERVICE_NAME and DISPLAY_NAME. Note that the space between the = and the next word are important. Not very unixy, that. http://www.ss64.com/nt/sc.html http://www.ss64.com/nt/net_service.html http://technet.microsoft.com/en-us/library/bb490995.aspx Show Sample Output

This command will first add an alias known only to git, which will allow you to pull a remote and first-forward the current branch. However, if the remote/branch and your branch have diverged, it will stop before actually trying to merge the two, so you can back out the changes. http://www.kernel.org/pub/software/scm/git/docs/git-pull.html Tested on git 1.5.6.1, msysgit (Windows port) Actually this is not really the way I want it. I want it to attempt a fast-foward, but not attempt to merge or change my working copy. Unfortunately git pull doesn't have that functionality (yet?). Show Sample Output

On Windows 2000 or newer, you can use the command line to save the current network interface info. You can then edit the text file and re-apply it using the netsh -f command (or netsh exec). Keep a bunch of text files around to quickly switch connection info without using extra software. http://en.wikipedia.org/wiki/Netsh http://support.microsoft.com/kb/242468 http://thelazyadmin.com/blogs/thelazyadmin/archive/2005/04/04/Using-Netsh-to-Manage-Network-Interfaces-Part-2.aspx Show Sample Output
