.I grep
(from "g/re/p") finds occurrences of a string in one or more files.
Here it finds Maja's telephone number.
-.SS "Path names and the current directory"
+.SS "Pathnames and the current directory"
Files live in a large tree, the file hierarchy.
Each has a
-.I "path name"
+.I "pathname"
describing the path from the root of the tree (which is called /)
-to the file. For example, such a full path name might be /home/aeb/tel.
-Always using full path names would be inconvenient, and the name
+to the file. For example, such a full pathname might be /home/aeb/tel.
+Always using full pathnames would be inconvenient, and the name
of a file in the current directory may be abbreviated by only giving
the last component. That is why "/home/aeb/tel" can be abbreviated
to "tel" when the current directory is "/home/aeb".
