New to UNIX

Im trying to learn UNIX so Im starting off with a small exercise.

1. Create a directory for each week of the a month called week1, week2, week3 and week4

2. Change the working directory to week1 and create a file called budget that contains food, cable, mortgage, car each on a separate line

3. Sort this file and append the results to the same file

4. Append the results of the pwd command to the file

Im OK with doing steps 1 and 2 but Im confused on steps 3 and 4.

Any help would be great!

Basically for (3) and (4)

sort file > tmp.file
cat tmp.file >> file
pwd >> file

Voila.

">"  redirects standard out to the target file ; and will create or overwrite that target
">>"  is the append operator. It will _not_ overwrite the target
