tar: failing commands

1 2.8.5 Commands That Will Fail
1 -----------------------------
1 
1 Here are some sample commands you might try which will not work, and why
1 they won't work.
1 
1    If you try to use this command,
1 
1      $ tar -xvf music.tar folk jazz
1 
1 you will get the following response:
1 
1      tar: folk: Not found in archive
1      tar: jazz: Not found in archive
1 
1 This is because these files were not originally _in_ the parent
1 directory '..', where the archive is located; they were in the
1 'practice' directory, and their file names reflect this:
1 
1      $ tar -tvf music.tar
1      practice/blues
1      practice/folk
1      practice/jazz
1 
1 Likewise, if you try to use this command,
1 
1      $ tar -tvf music.tar folk jazz
1 
1 you would get a similar response.  Members with those names are not in
1 the archive.  You must use the correct member names, or wildcards, in
1 order to extract the files from the archive.
1 
1    If you have forgotten the correct names of the files in the archive,
1 use 'tar --list --verbose' to list them correctly.
1 
1    To extract the member named 'practice/folk', you must specify
1 
1      $ tar --extract --file=music.tar practice/folk
1 
1 Notice also, that as explained above, the 'practice' directory will be
1 created, if it didn't already exist.  There are options that allow you
11 to strip away a certain number of leading directory components (⇒
 transform).  For example,
1 
1      $ tar --extract --file=music.tar --strip-components=1 folk
1 
1 will extract the file 'folk' into the current working directory.
