Needs xxdiff installed, which looks a bit clunky but is an extremely powerful graphical diff.

There is no need to use the shell or construct. Screen offers varius ways of detaching and reattaching. man screen and look for -[rRdD].

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.

You can convert a FAT or FAT32 volume to an NTFS volume without formatting the drive, though it is still a good idea to back up your data before you convert.

Tested on CentOS, Ubuntu, and MacOS.

This is useful for displaying a portion of a FILE that contains an error at line NUMBER

This will look through file and print the data in between the pattern matches. It's great for restoring tables from a mysqldump backup. You can then import it back into your database with:

You should really use keys. Really. I'm serious.

But if you have to add your key, change password etc. for a long list of servers, this might help.

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.

Same as 7272 but that one was too dangerous

so i added -P to prompt users to continue or cancel

Note the double space: "...^ii␣␣linux-image-2..."

Like 5813, but fixes two bugs: [1]This leaves the meta-packages 'linux-headers-generic' and 'linux-image-generic' alone so that automatic upgrades work correctly in the future. [2]Kernels newer than the currently running one are left alone (this can happen if you didn't reboot after installing a new kernel).

Perhaps a bit of a niche, but if you've even been frustrated by Oracles sqlplus command line tool for not supporting readline - have no fear. Socat is here to help you.

Shows a list of all installed cows saying a fortune. Also lists the cows names. Pic your favorite cow!

Needs cowsay, fortune and ruby installed. The path only applies to OS X with cowsay installed using homebrew. On Linux it might be /usr/share/cowsay/cows/ or similar. Uses ruby just because.

It's not better than the former, just another possible way.

The command finds all .mp3 files in all subfolders from where it's ran, catches its "relative path" and creates inside /new/path/ with the same "relative path".

PS: /new/path/ must exists

Use case: folder with flac files with tree structure ../artist/album/number-title.flac

1) convert flac->mp3 in the same folder: http://www.commandlinefu.com/commands/view/6341/convert-all-.flac-from-a-folder-subtree-in-192kb-mp3

2) search for mp3 files and recreate tree structure to another path: this command

3) move all mp3 files to that new folder: http://www.commandlinefu.com/commands/view/8854/move-mp3-files-to-another-path-with-existing-subtree-structure

As cp is often an alias to cp -i you can use \cp (or cp full path /bin/cp) to use the real cp command instead of its alias

Then, you can assign new accels to GTK menu actions pressing the keys while the option is active.

This command will remove only files, not directories: if you wish to remove both directories and files, just remove '-type f' from command above

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.

This commands will make it easier to select only common items between two files being compared. If your lines start with things other than lowercase a-z, adjust this Regex appropriately. Number of lines in the output has been set to no more than 10000, and should be adjusted as needed.
