 * Exclude certain files from a tar archive:
-  % tar -zcvf /home/backup.tar.gz --exclude='foo' --exclude='bar' /home/bob
+  $ tar -zcvf /home/backup.tar.gz --exclude='foo' --exclude='bar' /home/bob
 * Exclude directories from a tar archive (note: It is usually a good idea to give the absolute path to the directories you wish to exclude):
-  % tar -jcvf my_archive.tar.bz2 /dir/to/arhive --exclude '/dir/to/exclude1/*' --exclude '/dir/to/exclude2/*'
+  $ tar -jcvf my_archive.tar.bz2 /dir/to/archive --exclude '/dir/to/exclude1/*' --exclude '/dir/to/exclude2/*'
 * Or, list files to exclude in a file (one filename per line):
-  % tar -zcvf /home/backup.tar.gz -X exclude.txt /home/bob
+  $ tar -zcvf /home/backup.tar.gz -X exclude.txt /home/bob
