Works in Ubuntu, I hope it will work on all Linux machines. For Unixes, tail should be capable of handling more than one file with '-f' option.

This command line simply take log files which are text files, and not ending with a number, and it will continuously monitor those files.

Putting one alias in .profile will be more useful.

The variable WIRELESSINTERFACE indicates your wireless interface

Note that this assumes the application is an SVN checkout and so we have to throw away all the .svn files before making the substitution.

exported files will get a .r23 extension (where 23 is the revision number)

change 24073 to your pid

Just find out the daemon with $ netstat -atulpe. Then type in his name and he gets the SIGTERM.

will display typedefs, structs, unions and functions declared in 'stdio.h'(checkout _IO_FILE structure). It will be helpful if we want to know what a particular header file will offer to us. Command 'cpp' is GNU's C Preprocessor.

Tuned for short command line - you can set the path to sessionstore.js more reliable instead of use asterixes etc.

Usable when you are not at home and really need to get your actual opened tabs on your home computer (via SSH). I am using it from my work if I forgot to bookmark some new interesting webpage, which I have visited at home. Also other way to list tabs when your firefox has crashed (restoring of tabs doesn't work always).

This script includes also tabs which has been closed short time before.

The curl command retrieve the HTML text containing the IP address. The grep command picks out the IP address from that HTML text.

Get your colorized grep output in less(1). This involves two things: forcing grep to output colors even though it's not going to a terminal and telling less to handle those properly.

-l outputs only the file names

-i ignores the case

-r descends into subdirectories

Replace * with any filename matching glob or an individual filename

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

Useful to know, especially if you are dealing with output configurations in block size.

Tested on 'Red Hat'.

A good way to understand what you've let yourself in for. Potential project metric could be the count:

automatically add and remove files in subversion so that you don't have to do it through the annoying svn commands anymore

This is a simple but useful command to search for multiple terms in a file at once. This prevents you from having to do mutliple grep's of the same file.

Quick and easy way of validating a date format of yyyy-mm-dd and returning a boolean, the regex can easily be upgraded to handle "in betweens" for mm dd or to validate other types of strings, ex. ip address.

Boolean output could easily be piped into a condition for a more complete one-liner.
