Uses curl to download page of membership of US Congress. Use sed to strip HTML then perl to print a line starting with two tabs (a line with a representative)

Splits the input based on commas and prints it in a nice column format. This would not work for CSV rows that have "," between quotes or with newline characters. Use only simple simple csv files.

After this, just type:

beepwhenup

You need to install "beep" before this would make the beep sound.

Save it in your .profile if you want to use it later

How often do you make a directory (or series of directories) and then change into it to do whatever? 99% of the time that is what I do.

This BASH function 'md' will make the directory path then immediately change to the new directory. By using the 'mkdir -p' switch, the intermediate directories are created as well if they do not exist.

change the *.avi to whatever you want to match, you can remove it altogether if you want to check all files.

The sort utility is well used, but sometimes you want a little chaos. This will randomize the lines of a text file.

BTW, on OS X there is no

| sort -R

option! There is also no

| shuf

These are only in the newer GNU core...

This is also faster than the alternate of:

| awk 'BEGIN { srand() } { print rand() "\t" $0 }' | sort -n | cut -f2-
find . -name "*.txt" | xargs sed -i "s/old/new/"
svn diff $* | colordiff | lv -c

If the connection works you should see a "hello" on host A. If not: check your cabeling etc :-)

The ^$ within the quotes is a regular expression: ^=beginning of line, $=end of line, with no characters between.

cat -n file : number all line

You're behind on your TV catch-up, but how far behind? This command tries to open mplayer against all files in the current dir. If it's a video file it will contain ID_LENGTH, which is summed and output in hours, minutes and seconds.

Someone better at awk could probably reduce this down a lot.
