Commands using head

Enhancement for the 'busy' command originally posted by busybee : less chars, no escape issue, and most important it exclude small files ( opening a 5 lines file isn't that persuasive I think ;) )

This makes an alias for a command named 'busy'. The 'busy' command opens a random file in /usr/include to a random line with vim.

Tail is much faster than sed, awk because it doesn't check for regular expressions.

Silly approach, but easy to remember...

Useful for situations where you have word lists or dictionaries that range from hundreds of megabytes to several gigabytes in size. Replace file.lst with your wordlist, replace 50000 with however many lines you want the resulting list to be in total. The result will be redirected to output.txt in the current working directory. It may be helpful to run wc -l file.lst to find out how many lines the word list is first, then divide that in half to figure out what value to put for the head -n part of the command.

Not perfect but working (at least on the project i wrote it ;) )

Specify what you want search in var search, then it grep the folder and show one result at a time.

Press enter and then it will show the next result.

It can work bad on result in the firsts lines, and it can be improved to allow to come back.

But in my case (a large project, i was checking if a value wasn't used withouth is corresponding const and the value is "1000" so there was a lot of result ...) it was perfect ;)

This does the same thing that the command 'j_melis' submitted, but does it a lot quicker.

That command takes 43 seconds to complete on my system, while the command I submitted takes 6 seconds.

Replace the head -1 with head -n that is the n-th item you want to go to.

Replace the head with tail, go to the last dir you listed.

You also can change the parameters of ls.

Specify the size in bytes using the 'c' option for the -size flag. The + sign reads as "bigger than". Then execute du on the list; sort in reverse mode and show the first 10 occurrences.

You can actually do the same thing with a combination of head and tail. For example, in a file of four lines, if you just want the middle two lines:

Line 1 --\

being printed to screen (or wherever you redirect it).

Uses history to get the last n+1 commands (since this command will appear as the most recent), then strips out the line number and this command using sed, and appends the commands to a file.

Uses UNIX time for sorting.

Just increase the 1 at the end if you want to generate more than one.

(Alternative to "| head -n N" you could use the -b flag of od: -b $[6*N]

this command will beep like an alarm for one minute from 18:57. you can change "1857" to your desired time.

you should have alsa-oss package installed, and you should also be root or part of "audio" group.

Work only with bash and apt-file installed.

When it found an unknow command, it will search for a file named "scribus" (in my example), in a folder named bin and then install the corresponding package.

After installation, it will run the command.

Usefull juste after reinstalling linux and missing lot of package.

Pros: the format is very simple, there is no need to show every columns, and full command with args

the first column is memory consumption %

the second column is pid

the third is just the command (without full arguments, most application's arguments are too long)

You can decide which application to kill then.
