Examples
OSS pathnames can be absolute or relative. Absolute pathnames begin with a slash
(
/), which indicates the root directory. The following is an example of an absolute OSS
pathname:
/usr/ccomp/prog1.c
Relative pathnames (which do not begin with a slash) are relative to the OSS current
working directory. Examples of relative OSS pathnames follow:
refman/ch1 Refers to a file (ch1) in a subdirectory (refman) of the
current working directory.
./refman/ch1 Refers to the same file as the previous example.
../yourfiles/oldmail Refers to a file (oldmail) in a subdirectory
(
yourfiles) of the parent directory of the current
working directory.
/E/forty/usr/ccom/prog1.c Refers to a OSS file name (prog1.c) in a
subdirectory (
ccom) in a subdirectory (usr) in a
subdirectory (
forty) after the E root directory.
/E/forty/G/books/donl/text180 Refers to a Guardian file name (text180) in
a subvolume (
donl) in a volume (books) on the HP
node (
forty).
