mysamplefile. This gives you a file to play with when using gzip.

$ ls -l
Lists the contents of the current directory. Note the size of
mysamplefile.

$ gzip mysamplefile
Compresses mysamplefile.

$ ls -l
Observe the results of this command: mysamplefile is now called
mysamplefile.gz . It's also a good bit smaller.

$ gunzip mysamplefile.gz; ls -l
This uncompresses the file. Observe that mysamplefile has returned to its
original state. Notice that to uncompress, one uses gunzip, not gzip.

$ rm mysamplefile
Use this command to remove the file, since it was just to practice with.

Finding Files

There are two different facilities for finding files: find and locate.
find searches the actual files in their present state. locate searches an
index generated by the system every morning at 6:42 a.m. (this is a cron
job, explained elsewhere in this book). locate won't find any files that
were created after the index was generated. However, because locate
searches an index, it's much faster - like using the index of a book
rather than looking through the whole thing.
