Uses inotifywait from inotify-tools ( http://wiki.github.com/rvoicilas/inotify-tools/ ), that is compatible only with linux.
Usefull when you work with files that have to be compiled.. latex, haml, c..
Get colorful fortunes dictated by an ASCII cow. For full enjoyment you'll need to have color setup enabled for your terminal.
if you dont want to alias also then you can do
killall rapidly_spawning_process ; !! ; !! ; !!
Use this if you can't type repeated killall commands fast enough to kill rapidly spawning processes.
If a process keeps spawning copies of itself too rapidly, it can do so faster than a single killall can catch them and kill them. Retyping the command at the prompt can be too slow too, even with command history retrieval.
Chaining a few killalls on single command line can start up the next killall more quickly. The first killall will get most of the processes, except for some that were starting up in the meanwhile, the second will get most of the rest, and the third mops up.
More recent versions of the date command finally have the ability to decode the unix epoch time into a human readable date. This function makes it simple to utilize this feature quickly.
Cleans all files in /tmp that have been accessed at least 2 days ago.
If you have lots of subversion working copies in one directory and want to see in which repositories they are stored, this will do the trick. Can be convenient if you need to move to a new subversion server.
not the best, uses 4 pipes!
previous version leaves lots of blank lines
Case Insensitive! and Works even if the "<title>...</title>" spans over multiple line.
the last person who posted used the most roundabout way to concatinate files, there's a reason there's a "conCATinate" command... Using this method, you also get to choose the order of the files, below another person just did *.txt > combined.txt which is fine but the order depends on the implementation of "cat" which is probably alphabetical order of filenames.
extension to tali713's random fact generator. It takes the output & sends it to notify-osd. Display time is proportional to the lengh of the fact.
Though without infinite time and knowledge of how the site will be designed in the future this may stop working, it still will serve as a simple straight forward starting point.
This uses the observation that the only item marked as strong on the page is the single logical line that includes the italicized fact.
If future revisions of the page show failure, or intermittent failure, one may simply alter the above to read.
wget randomfunfacts.com -O - 2>/dev/null | tee lastfact | grep \<strong\> | sed "s;^.*<i>\(.*\)</i>.*$;\1;"
The file lastfact, can then be examined whenever the command fails.
Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc.
Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this.
Make sure your server's date is correct, otherwise insert your own serial number.
should usually follow this command.
Bash scrip to test if a server is up, you can use this before wget'ing a file to make sure a blank one isn't downloaded.
Just after you type enter, you have 3 seconds to switch window, then "texthere" will be "typed" in the X11 application that has focus. Very useful to beat your score at games such as "How fast can you type A-Z".
The `export` is unnecessary if it's only applicable to the one command.
Like the given command, but combines _DISPLAY=":0.0"_ with _export DISPLAY_ to get _export DISPLAY=":0.0"_ and only imports if DISPLAY is set successfully.
