Not always does Xorg run on :0. For times like those, this script allows you to find out which it is.

It is not easy to make perl give a segfault, but this does it. This is a known issue but apparently not easy to fix. This is completely useless except for showing people that perl is not bullet-proof.

This is a useful command that gives the hostname and the IP Address of your machine, on many OS. Tested on Linux and Solaris.

host command here is followed by `hostname`. Note the ` in the command is a back quote (or grave accent or back tic that usually shares the space with the ~ key). No other options are specified. See sample output.

another replacement for cat.

Uses curl, xmlstarlet and festival to speak your horoscope. Modify the m (month) and d (day) parameters to the astrology web service to hear your personal horoscope.

Read and execute commands from FILENAME in the current shell. The entries in $PATH are used to find the directory containing FILENAME. If any ARGUMENTS are supplied, they become the positional parameters when FILENAME is executed.

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.

Tested on Windows XP

I've seen some versions of hostname that don't have the -i option, so this may not work everywhere. When available, it's a better alternative than using ifconfig and wasting eyeball muscle to search for the address, and it's definitely simpler than using awk/sed.

Easy way to grab the IP address of a machine for easy script use. If needed a "| grep -v 127.0.0.1" at the end will suppress localhost.

same, except it works on any OS with Perl installed. DOS, Windose, whatever

Ever wanted to find the most recently modified files, but couldn't remember exactly where they were in a project directory with many subdirectories? The "find" command, using a combination of "-mtime -N" and "-depth -D" can be used to find those files. If your directory structure isn't very deep, just omit the "-depth -D", but if your directory structure is very deep, then you can limit the depth of the traversal using "-depth -D", where "D" is the maximum number of directory levels to descend.
